Testing the Digital Level
Required tools: digital level
Perform this test before each use of the digital level and any time the digital level has been dropped or is
being used in an environment that varies ±9
°
F from the environment in which it was last calibrated. If the
digital level fails the accuracy test you must re-calibrate the level before use.
1 Turn on the level by pushing the ON/OFF button. Position the level with the display facing you and the
text on the face of the level right-side up. Ensure that the level is on a clean, flat, and horizontal surface.
This surface does not have to be exactly level. Wait 10 seconds for the level to completely settle and
take note of the angle on the display.
2 Rotate the level end-for-end so the display is facing away from you. The screw on the back of the level
should be on the left side. Be sure to set the level in the exact spot as in Step 1. Wait 10 seconds for
the level to completely settle and take note of the angle on the display.
3 Roll the level toward you so that the display is facing you, but the lettering on the face of the unit is
upside down. Be sure to set the level in the exact spot as in Step 1. Wait 10 seconds for the level to
completely settle and take note of the angle on the display.
