Calibration (Figs.3,4)

Place the digital level on a at and smooth surface, push and hold the REF button for about 3 seconds, the calibration mode is activated.

“CAL1” will wink on LCD.

Keep it unmoved for seconds until hear the beeper sounds for 1 second, then “CAL2” will show on LCD.

Rotate the level 180º in the same location then press the REF button, “CAL2” will wink, keep it unmoved for seconds, then the beeper

will sound for 2 seconds to tell calibrating completed, the LCD will show the current angle in high-accuracy-display.

Important NOTE:

The digital level has been pre-calibrated to high-accuracy-display mode. It possibly runs to rough-accuracy-display mode if the

temperature changes too much. Suggest calibrating the digital level every time before you use it.

To ensure an accurate measurement, the calibration should be performed separately for horizontal measurement, plumb measure-

ment or upside measurement.

The calibration must be performed on a at and smooth surface with the gradient no more than 5º. If it exceeds 5º, the beeper will

be buzzing for 3 seconds, “Err” will show on the LCD to tell the calibration failed, then exits automatically.

In the calibration, the level also can not be beveled or moved, same Err will occur with the wrong operation.

After CAL1 is nished, the level should be rotated 180 degree to start CAL2, if keep the level not moved and start CAL2, the

digital display will wrongly set the current working surface as 0°, it will recover to normal function after a correct calibration.

The high accuracy display is only available when the display unit switches to degree or % and the gradient must be within 1º. If

the gradient exceeds 1º, LCD will recover to rough accuracy display.
