CHECK AND CALIBRATION
IMPORTANT
Calibration of inclinometer:
- before first use
- before important measurements
- after a hit or drop
- after a large fluctuation in temperature
CHECK OF CALIBRATION
Set the instrument down on a flat and even surface and switch it on. Wait 3 sec.
and note down the measured value (A). Turn the unit by 180° and set it down
on the same position as before. Wait 3 sec. and note down the measured value
(B). If the deviation between the two values A and B is more than 0,2° the unit
has to be calibrated.
CALIBRATION
Set the instrument down on the same flat and even surface, switch it on and
keep the button CAL pressed until the display shows „-0-" . Wait approx. 3 sec.
and press the button CAL again until the display shows „-1-" . Turn the unit by
180° and set it down on the same position as before. Wait approx. 3 sec. and
press the button CAL again until the display shows „-2-" . Now the calibration is
completed.
MEASUREMENT OF INCLINATION
The two arrows in the display indicate in which direction the
instrument has to be moved in order to reach the 0° or 90°
position.
The exact 0° or 90° position is shown by double arrows.
The display has an automatic digit inversion for over-
head measurements.
