ample, do not leave it in vehicles for a long

allow the digital level to adjust to the ambient
temperature before putting it into operation. In
case of extreme temperatures or variations in

tal level. After severe exterior effects to the
digital level, it is recommended to carry out an
accuracy check (see "Checking the Measuring
Accuracy") each time before continuing to
work.
Press the "ON/OFF" switch 9 to switch the
digital level on or off.
If no button on the digital level is pressed for
approx. 30 mins or the grade of the digital level
is not changed by more than 1.5°, then the
grade measurement and the display are auto-
matically switched off to save the battery.
Check the accuracy of the digital level each
time before using, after extreme temperature
changes as well as after heavy jolts or impact.
Before measuring angles <45°, the accuracy
check should take place on a level and horizon-
tal surface; before measuring angles >45°, on a
level and vertical surface.
Switch the digital level on and place it on the
horizontal or vertical surface.
Wait for 10s and write down the measured
value.
Rotate the digital level (as shown in the figure)
by 180° around its vertical axis. Wait again for
10s and write down the second measured vale.
Calibrate the digital level only when the dif-
ference between both reading values is great-
er than 0.1°.
Calibrate the digital level in the position (ver-
tical or horizontal), in which the difference of
the measured values has been determined.
The horizontal surface used to calibrate the
tool cannot slope more than 5°. If the slope is
greater than 5°, the calibration is discontinued
and "---" will display.
