ADJUSTMENT
Response speed
Select the desired response speed using the response speed selector
switch.
Sensitivity
Select the appropriate sensitivity using the sensitivity selector switch.
Zero adjustment
1. When the target is displaced from the reference position, the analog
output voltage may deviate from the zero point. The 0-ADJ adjust-
ment trimmer can be used to adjust the reading to the zero point.
2. Confirm that the value of the output voltage is in proportion to the
displacement of the target. If not, adjust the output voltage with the
SPAN adjustment trimmer.
3. Confirm that the analog output voltage is 0 v at the reference position.
If not, repeat the above adjustment procedures.
