How to measure voltage
output on OP light?
Measuring output voltages and
current on the CA-013 cable
Disconnect the cable CA-013
and CA-066 situated in the OP
lamp arm.
In voltmeter Mode:
Measure the output voltage of
the CA-013 (between 24 and
25VDC).
In Ampere mode (mA)
Measure the intensity output on
CA-013 (same contact)
