Keysight U3606B Service Guide 89
Output adjustments
The instrument calculates and stores output corrections for each output level. The
U3606B implements a closed loop output calibration procedure to its inherent
dual function ability as a digital multimeter and a DC power supply. The output
constant is computed from the calibration level set for the calibration command
and from measurements made automatically during the adjustment procedure.
Adjustments for each function should be performed ONLY in the order shown.
Valid output adjustment levels
Output adjustment can be accomplished using the following output levels.
Front and rear terminal output adjustment The U3606B Multimeter | DC
Power Supply needs to be calibrated twice — once for the front panel output
terminals and again for the rear panel output terminals. When you have
completed the voltage and current output adjustments for the front panel
output terminals, repeat the entire adjustment procedure again for the rear
panel output terminals.
