4.4.2 Adjustments
The scanning amplitude is adjustable with the scanning angle (0 to 4 °),
the scanning frequency between 4 and 10 Hz.
On the left side of the pyrometer is a cap. Two adjusting potentiometers
are under this cap, labeled with an A for amplitude and an F for
frequency. For adjustments a small screw driver is necessary. With the
laser targeting light the adjustments can be controlled.
Note: Please make sure that the pyrometer will not be contaminated while the cap is
open.
The potentiometers can be turned 25 revolutions from
min to max. To switch off the scanning mirror, the
amplitude potentiometer has to be turned until the laser
targeting light does not move. Then the measuring spot
is centered. The speed of the scanning can be adjusted
with the frequency potentiometer, the current speed can
be watched by the speed of the moving laser spot.
Note: The potentiometer has no mechanical stop position. Turning the potentiometer
to the left decreases the values, turning right the values are increasing.
After making the required adjustments, ensure that you re-install the cover.
