Final Adjustment
•
Set the switch on the adjustment unit to AUTO-RANGE.
•
Using the knurled screws, fine-adjust the detector lens to display the maximum level
in the RANGE display.
Note: The knurled screws should be turned slowly in order to avoid large signal
•
When the maximum value is obtained, (it must be between min. 4 and max. 13) set
the switch to FIX-RANGE. The range level is now programmed into the detector to
set the internal amplifiers.
•
Adjust the knurled screws to display the maximum level in the SIGNAL display.
Caution: If the signal value can be adjusted to >60, the range level was not ad-
justed to its maximum. Switch back to AUTO-RANGE and readjust to the maximum
range level. Then repeat the signal level adjustment.
The RANGE and SIGNAL levels on the adjustment unit should both be set to the
maximum.
•
Engage the locking screws.
•
Switch the adjustment unit to FIX-RANGE.
•
Cover the reflector.
Completely cover the reflector with a dark cover. The signal should decrease to <2.
If this is not the case, the detector has not been aligned to the reflector but to a
reflecting obstacle in the environment of the measurement section. Repeat the
adjustment procedure.
•
Disconnect the adjustment unit from the detector.
•
