Calibration Information
The device must be calibrated every 7 calender days. When calibration
is required, the device will display a message to calibrate before
allowing the user to read a vehicle.
You should recalibrate the device if ambient conditions have changed.
This applies especially when changing location and if major changes in
temperature and relative humidity may be expected as a result (for
example inside/outside).
When moving from cold areas to warm areas, there is a danger of
condensation. For this reason, after there has been a change in
ambient conditions, you should wait for an appropriate amount of time
to allow the optical components to adjust before calibrating and using
the unit.
Calibration Notes
• Dirt or dust in the optics area will cause an inaccurate calibration
reading. Therefore, always use the protective cap if no readings are
taken.
• The white standard is dramatically affected by dirt, dust and finger
prints. For cleaning procedure see section "Cleaning and
Maintenance“.
• The black trap should be cleaned periodically. It can be taken
apart for easy cleaning. For cleaning procedure see section "Cleaning
and Maintenance“.
• Before you position the instrument on the black trap, make sure that
you have removed the hole plug. After having calibrated the instrument,
close the black trap with the hole plug again. Always store black trap
with hole plug in place when not in use.
• Use the alignment marks on the instrument, the white standard and
the black trap when you position the instrument into the indentation of
the white standard or the black trap.
• Do not move the instrument while taking a calibration measurement.
If motion is detected, an error message will be displayed and
calibration aborted.
