Using serial commands
ACAL <cr>
The outputs on channels 1 and 2 are measured and the measured values (mA
or V) entered as calibration coefficients.
Example: both channels have 0...10 V outputs (set with AMODE command);
enter the voltages measured at the analogue outputs:
>ACAL <cr>
Ch1
U1 ( V ) ? 0.123 <cr>
Ch1
U2 ( V ) ? 9.980 <cr>
Ch2
U1 ( V ) ? 0.120 <cr>
Ch2
U2 ( V ) ? 9.980 <cr>

Using display/keypad commands
•
Connect an ammeter/voltmeter to the output of channel 1, select Cali
in the main menu and Analog outputs in the Cali menu. The follow-
ing is displayed (the quantity can be either mA or V):
•
Enter the measured lower end current/voltage on channel 1.
•
Enter the measured upper end current/voltage on channel 1.
•
Connect the meter to the output of channel 2 and enter the measured
lower end current/voltage on channel 2.
•
Enter the measured upper end current/voltage on channel 2.
