Output adjustments
The instrument calculates and stores output corrections for each output 
level. The U3606A 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 U3606A 
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.
