Yes. All the Digi-Pas^® Precision Digital Levels have already been calibrated in our factories before they are shipped out. You can actually use the Digital Levels right away, but we highly recommend that you perform a self-calibration before using to ensure its maximum accuracy.

It is recommended for users to calibrate their measuring tools and instruments periodically to ensure maximum accuracy conformance. Sometimes, improper handling, transporting, storing (e.g. out of specified storage temperature range) and accidental exposure to physical shock (e.g. dropping or hitting the device against some hard objects) may affect the accuracy of the device.

Digi-Pas^® digital levels has a smart built-in feature which enable users to perform self-calibration with ease to set their digital levels back to its factory accuracy. Users can refer to the respective Instruction Manuals for guidance on performing self-calibration, or simply watch our videos and follow the steps on How to Calibrate.

Whenever you have doubt over your digital level's accuracy, or when you have unintentionally dropped or overheated (e.g. overexposure to heat with extended time period) the device. You can perform a quick check on your digital level by placing it on a clean flat surface and read the displayed reading in two directions (0° and 180°), ensuring that the device is placed in the exact location.

The device does not require a calibration in two situations:

1. The two readings in reversed facings/directions are the same value. (e.g. 0.0° or 0.1° or and 0.05° depending on model)
2. The two readings are different, BUT within the tolerance of the device (E.g. either 0.05° or 0.1° depending on the model)

The device requires a calibration when:

1. The difference of the two readings are greater than the device's resolution or completely out of range.
2. You may re-calibrate the digital level by following the videos in this link or instructions in your user manual.

For horizontal calibration (steps 1 & 2), the surface onto which user place the digital level must not deviate from the horizontal level by more than 1° for optimum calibration result. Whereas for vertical calibration (steps 3 & 4), user must place Digi-Pas® digital level on true vertical surface to achieve an optimum calibration result.

Alternatively, user may contact respective Manufacture's Representative/Distributor to assist competent calibration at designated accredited 3rd party independent calibration service providers nearby user's geographical region.

Please see Digi-Pas® instruction manual for details.

Likewise to any measuring tools or instruments, accidentally dropping your digital level or storing outside its specified temperature range affects the accuracy of your device. There may potentially be structural deformation that results from the mechanical shock on impact when dropped or thermal expansions and contractions when stored at an inappropriate temperature.

However, unlike traditional 'bubble' spirit levels and most digital levels available in the market, all Digi-Pas^® digital levels are built with user's Self-Calibration feature. This feature allows users to perform their own calibration without having to send it to laboratories for minor calibrations, incurring a cost and time as a result. Conveniently, users may simply reset the Digi-Pas^® digital level back to its factory accuracy whenever there is a doubt over the measuring tool's accuracy.

This situation may happen if the digital level is placed on a rough, dirty or uneven surface. Digital levels are highly sensitive to uneven surfaces and the angle measured on these surfaces will be inaccurate. Ensure that the contact surfaces are smooth and clean in order to achieve consistent readings. For example, to check your digital level's accuracy (0.1° or 0.05° depending on model), a clean glass surface table finish is generally required.

Your digital level may have been subjected to extreme physical shocks or temperature swings during usage, transportation and storage that may have affected its accuracy. All Digi-Pas^® digital levels are built in with a Smart feature which empowers the user to perform Self-Calibration at ease. For more information on how to calibrate, see video links on How to Calibrate.

For Digi-Pas^® digital levels with a resolution of 0.1° (DWL80E and DWL200), the tolerance of these digital levels is ±0.1° at 0° and 90°. For example, when placed on the table, the digital reading is 0°. After turning the device 180°, the reading should be 0° or 0.1°. If the readings differ by more than 0.1°, the digital level should be re-calibrated. For Digi-Pas^® digital level models with a resolution of 0.05° (DWL80Pro, DWL180, DWL280 and DWL600F), the tolerance of these digital levels is ±0.05° at 0 and 90°. Similarly, if the readings differ by more than 0.05° when tested in two different directions (0° and 180°), the digital level should be re-calibrated.

The accuracy of Digi-Pas^® digital level is independent and higher than the built-in spirit Vial/Bubble. For example, the accuracy DWL-280 model is at ±0.05° (refer to calibration certificate webpage), but the built-in Vial "bubble" ° accuracy is only ±0.5° although the "bubble" seems rather sensitive.

Having built-in spirit vials or 'bubble' in our digital levels helps conventional users to relate to those traditional spirit levels that they are familiar with. In fact, the accuracy of Digi-Pas^® digital level surpasses greatly to the built-in spirit vial and is independent of the spirit vial's accuracy. While the spirit vials only have an accuracy of ±0.5°, advanced MEMS technology Digi-Pas^® digital level's accuracy is at 0.05° or 0.1° depending on the model.

Depending on the model, the Digi-Pas^® digital levels have an accuracy of ±0.05° or 0.1° at 0° & 90°; and ±0.2 or ±0.3° at other °. Meanwhile, the spirit bubble vials have only an accuracy of ±0.5°.

For Digi-Pas^® digital level models having a resolution of 0.05° (e.g. models such as DWL-80Pro, DWL-180, DWL-280 and DWL-600F), the tolerance of these digital levels at 0 and 90° is ±0.05°. If the digital level is initially placed on the table and it reads 0.00° and thereafter when the digital level is turned 180° and placed at the same place, it should read 0.00 or 0.05°. If it displays neither those readings, recalibrate the level.

For Digi-Pas^® models having a resolution of 0.1° (e.g., DWL-80E and DWL-200), the tolerance of these digital levels at 0 and 90° is ±0.1°. If the digital level is initially placed on the table and it reads 0.0° and thereafter when the digital level is turned 180° and placed at the same place, it should read 0.0° or 0.1° or -0.1°. If it displays neither those readings, recalibrate the level.

If the display reading 'flickers' or show no readings at all during measurements, it could mean that the digital level has not been used correctly. Users is required to ensure that their Digi-Pas^® digital levels are placed on its designated base firmly (i.e. without rocking) on the surface to be measured.

Click on the following link to see a video on how the Digi-Pas^® digital levels are properly used, .

The Alternate Zero function allows user to pick an angle and designate it as an "alternative zero angle point". This feature helps user to skip having to do the math for finding angles relative to a referenced angle set as 0°.

For example, the user has a table surface set at 5.0° and user would want to measure the angle of an object relative to (placed on) the table top. A Digi-Pas^® digital level could be placed on the table surface and pushed the "alt zero" button. Thereafter, user could measure the object placed on the same table surface (same direction) and if reading shows 10.0°. This means that relative to the table surface, the object's angle measured is 10.0°. However, relative to the 'floor' where the table's based stands/floor, the measured angle is 15.0°.

All Digi-Pas^® digital levels are warrantied for a period of one (1) year from the date of purchase. The warranty covers defects in workmanship or materials at no charge. The manufacturer reserves the right to repair to its working condition or replace a new device at its discretion.

However, the one (1) year warranty clause is NOT applicable to the European Union (EU) member states. Purchases made in EU member states are covered by the existing consumer laws across the EU countries, which provide statutory warranty rights in addition to the one (1) year warranty coverage.

Not all Digi-Pas^® digital levels are waterproof. Waterproof models are DWL280Pro and DWL680Pro. In addition to being waterproof, these models are also shock-, dust- and freeze-proofs. For the remaining models (DWL80 Series, DWL100 Series, DWL200 Series, DWL600F and DWL1000XY), they are only dust-resistant. Any water damage voids the warranty coverage.

DWL280Pro Waterproof Digital Level has been tested and approved for IP67. User is required to ensure that the battery cap is completely tightened after inserting batteries into the battery compartment. The battery cap is completely tightened when the O-ring is compressed into the space between the cap and compartment to prevent water enter the compartment.

For DWL680Pro, users must make sure that the battery compartment's tab lock is locked properly. The lock is secured when you hear a soft click.

Failure to do so will cause water to seep into the battery and electronic compartment, damaging the entire device and potentially voiding the warranty. For detailed information, please refer to the instruction manual

No, not all models have a wide operating temperature range. Most models have an operating temperature ranging between 0°C ~ +50°C and may not be suitable for extreme temperature working environment. Continuously putting the digital levels on the hot surface may potentially deform the plastic casing and damage the electronic unit, thus voiding the warranty.

For DWL280Pro and DWL680Pro, both models have a wider operating temperature ranging between -20°C ~ +60°C (-4°F ~ +140°F). These models can operate at hot working environment as well as in freezing weathers.

Note: The DWL80 Series have no buzzer feature.

The buzzer sound can be turned on or off by simply pressing the 'Alternate Zero' button for more than 3 seconds while observing the buzzer sign on/off on the display screen. The buzzer is turned ON when the buzzer sign appears on the display screen. If there is no buzzer sign displayed, it means that the buzzer is OFF.

The DWL600 series has a different way to turning ON/OFF its buzzer. Please refer to the instruction manual for more details.

No, the buzzer has a standardized volume for all Digi-Pas^® digital levels.

All Digi-Pas^® digital levels are designed with intelligent software based on advance Embedded Technology. The sensor automatically detects a situation whereby the digital level is not used for approximately 3 consecutive minutes and automatically cut off its power to preserve battery life. However, if the digital level is still in use (i.e. sensing some movements), the display screen continue to display up to a maximum of 10 minutes before power is cut off.

Traditional spirit level, pendulum-based digital level and inclinometer were constrained with (i) single axis, (ii) narrow angle measurement range, (iii) large footprint/size and (iv) inability to withstand high shock/impact applications. Single-axis inclinometer is also susceptible to cross-axis error particularly when measuring at larger angles and higher precision. However, precision levelling, angle measurement, alignment and surface flatness profiling tasks essentially involve 2-dimensional plane rather than two independent orthogonal single-axis lines. Digi-Pas^® 2-Axis precision inclinometer utilizing advanced MEMS technology provides simultaneous 2-axis and wide angle measuring range capabilities that traditional bubble vials levels and single-axis pendulum-based inclinometers are unable to offer.

Utilizing Digi-Pas^® 2-axis inclinometer translates into speedy machine installation and productive maintenance works with professional quality that maximizes precision machine performance. Thus, leads to improved user's product quality (e.g. accuracy & yield) and higher customer satisfaction.

Digi-Pas^® 2-axis digital inclinometer provides a comprehensive solution for precision levelling and angular measurement, and serves as a superior alternative that seeks to replace the use of outdated spirit levels and limited angle-measuring range of conventional single-axis inclinometers.

Yes. Digi-Pas^® Precision Digital Levels have been calibrated and tested by accredited 3rd party independent bodies in the USA, UK, Germany and Japan in accordance with ISO/IEC 17025:2005 and/or ANSI/NCSL Z540-1 standard, traceable to NIST, JIS & DIN under ILAC & A2LA.

It is recommended for users to calibrate their measuring tools and instruments periodically to ensure maximum accuracy conformance. Sometimes, improper handling, transporting, storing (e.g. out of specified storage temperature range) and accidental exposure to physical shock (e.g. dropping or hitting the device against some hard objects) may affect the accuracy of the device.

Digi-Pas^® digital levels has a smart built-in feature which enable users to perform self-calibration with ease to set their digital levels back to its factory accuracy. Users can refer to their manuals (http://www.digipas.com/support/catalogue.php) for instructions on self-calibration, or simply watch our videos and follow the steps on how to calibrate (http://www.digipas.com/support/video.php)

This situation happens when the precision level is placed on a rough, dirty or uneven surface. Precision digital levels are very sensitive to surface unevenness where placed. Ensure that the machine contact surfaces are clean and smooth to get consistent readings. E.g. to check/verify your precision level of 0.01° accuracy, a typical machined surface is generally adequate. However, for precision level of 0.001° accuracy, a grade AA Granite Table (or an equivalent surface flatness of ≤3µm) is required.

Your precision digital level may have been subjected to extreme physical or temperature shocks during usage, transportation or storage that affected its accuracy. An offset value of reading may have been present. Digi-Pas^® precision digital level has a smart built-in feature that empower users to perform self-calibration to completely remove any residue offset and set the device to its factory accuracy. See video links on how to perform “User-Self Calibration”

Alternatively, users may choose an easy 'quick solution' to simply perform the Absolute Level Setting on the surface of the object to be measured to remove any residual offset on each measurement to be taken.

Yes, users could perform self-calibration for Digi-Pas^® 2-axis precision levelling devices. However, precision digital levels are very sensitive to surface unevenness, hence appropriate set up procedures with a Granite table and Master Square are required.

It is well-known that Vibration caused by improper levelling (machine footings uneven weight load distribution - result in machine 'rocking'!) affects high precision equipment/machine accuracy performance. Typical applications found in Continuous vibration magnitude recording/monitoring among multiple machines relative vibration on precision CNC machines can improve production yield and reduce scraps. Very useful in Coordinate Measuring Machines (CMM), SEM, MRI to achieve high quality 'sharp' images thus ensuring optimum measurement accuracy.

Digi-Pas^® High Precision Dual Axis Digital Level with built-in Vibrometer (sampled at =10mS) allows user to record vibration patterns on precision equipment/instrument/machines and also their surrounding floor vibration and topographic changes over an extended period of time (i.e user defined) to identify vibration magnitude/pattern and analysis for achieving high quality machine levelling, alignment during setup and preventive maintenance.

Yes. The mounting base of Digi-Pas^® 2-axis precision levelling devices are provided with screw mounting holes. Users may refer to the Instruction Manual for further details. Please click here.

No. You need to use the Professional version PC Sync software to save data into PC as there is no internal built in memory space in the device.

Industrial Class 1 Bluetooth is used in Digi-Pas^® devices and it has an effective range of 30 meters. However, most Laptop PC or tablet is built with consumer's grade Bluetooth hardware having shorter communication range. The effective communication range can be further extended beyond 30 meters when user's Laptop PC or Mobile Tablet is adapted with similar Industrial class 1 Bluetooth hardware as well.

Likewise to any high precision measurement instrument/tool, mishandling such as dropping a digital level to floor or storing it outside the specified temperature range could affect its accuracy. This is primarily due to structural deformation resulted from mechanical shock on impact when dropped and physical micro-dimensional changes resulted from thermal expansion or contractions when storage temperature exceed maximum specified range.

However, unlike traditional 'bubble' spirit levels and many other digital levels in the market, all Digi-Pas^® digital level is built with User's Self-Calibration feature. This feature empowers users to perform their own calibration without the need to sending to 3rd party testing laboratory when minor mishandling the device. At user's convenient work site or field work, User's Self-Calibration can simply reset the Digi-Pas^® digital level back to factory preset accuracy whenever he/she is in doubt with the accuracy of the digital level. For more information on accuracy please click here.

4 pieces of AAA batteries would last for over 6 hours in continuous use (i.e. LCD continuously turned ON). The firmware has intelligent power management system to automatically dim the display (i.e. user defined) for preserving power and prolong battery life over 12 hours.

Unlimited extension of battery life of the instrument can simply be achieved through the use of USB external power source connected to the USB terminal of the instrument. Also, when in Sync with PC, the USB cable link automatically supplies power to the instrument without the need of using the battery.

The warranty period for these device is 2 (two) years from the date of purchase. Please refer to Digi-Pas® warranty agreement webpage here for further details.

For all precision digital levels, there is a “warming up” period during the initial power ON. The thermometer symbol on the display screen indicates that the device is warming up. The thermometer that is flashing ON and OFF is for tracking of the instrument’s internal temperature changes. Once the device is warmed up and device temperature is stabilized, the thermometer should turn green color.

Sometimes, the thermometer will flash ON and OFF again (red and green light) due to a slight change in temperature. You may continue to use the device once the device temperature stabilizes and the thermometer turns green color.

Note: Users are recommended to power ON the device first for up to 15minutes to allow device to stabilize before usage.
