4. 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 un-
evenness due to rough surfaces or dirt, etc.). Please put a device on smooth surfaces
to re-calibrate again.

3. QUESTION AND ANSWER
1. Why device LED screen is showing only blinking BT icon?
Blinking “BT” icon indicates the device has not been initialized yet. Users are required to
initialize the device by launching “Digi-Pas®Machinist Level” App on your smartphone
through Bluetooth connection. Guide on how to pair and initialize the device with your
smartphone is in the App. “Digi-Pas® Machinist Level” app must be rst downloaded to
your smartphone from Google Play Store or Apple App Store.
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.youtube.com/watch?v=3Me8C0YhnAs 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
measurement to be taken.
