5. Place the device to position 4 (screen downward). Press “MODE” button once
again and wait until countdown reaches “0”. LCD screen automatically switch to
measuring mode once calibration step 4 is completed.
6. Verify your calibration result by comparing the measurement value of current posi-
tion with the device after turning 180° (in reverse position). If displayed measurement
value differs >0.001°, the device has not been calibrated properly (e.g. surface
unevenness due to rough surfaces or dirt, etc.). Please put a device on smooth sur-
faces to re-calibrate again.

3. QUESTION AND ANSWER
Why device display value is not zero when placing on a at surface?
This situation happens when a precision level is placed on a rough, dirty or uneven sur-
face. Precision digital levels are very sensitive to surface unevenness where it is placed.
Ensure that contact surfaces are clean and smooth to get consistent readings.
Digi-Pas®precision digital level has a smart built-in feature that allows users to perform
self-calibration to completely remove any residue offset value and set the device to
its factory accuracy. See video links in www.digipas.com/1900xy-calibration on how
to perform “User-Self Calibration”. An alternative to perform self-calibration steps, 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 meas-
urement to be taken.
1. Why do I get two different readings when placing the device on front facing, and then
replacing it on the reversed facing?
Your precision digital level may have been subjected to extreme physical or tempera-
ture shocks during usage, transportation or storage that affected its accuracy. An
offset value of reading may have been present in the device. Digi-Pas®precision digi-
tal level has a smart built-in feature that allows users to perform self-calibration to com-
pletely remove any residue offset in the device and set the device to its factory accu-
racy. See video links in www.digipas.com/1900xy-calibration how to perform “User-Self
Calibration”. An alternative to perform self-calibration steps, 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 off-set on each measurement to be
taken.
2. Digipas Smart Levels App unable to pair with a device. What should I do?
Device battery level might be low, please replace 2 new batteries.
3. Digipas Smart Levels App is unable to nd device. What should I do?
Please ensure device Bluetooth is enabled to establish wireless connection. To enable/
disable Bluetooth connection, press and hold device’s MODE button.
