3. Short all phases to neutral using a shorting jumper
4. You can connect the DMM to the output of phase A as shown in the figure above but it
is not required for this calibration step.
5. IMPORTANT: Program both AC and DC voltage (depending on voltage mode) to all zero
volts to avoid any current from flowing into the shorted outputs. Use PROGRAM screen
to make sure both AC and DC settings are zero.
6. Enable the Output with the output shored.
7. Press "Cal V. offset" soft key
8. Wait for the V offset coefficients for all phases to be calculated and displayed
9. Remove the shorting jumper when done
Note: The Mode, Voltage and Current edit boxes do not affect this function.
11.4.2 Current Calibration - Offset
The procedure to calibrate current offset is:
1. Select the Calibration entry from the "System" menu
2. Press the "Calibrate" soft key to enter calibration mode
3. Do not connect any load to the output
4. Enable the Output with no load connected
5. Press "Cal I. offset" soft key
6. Wait for the I offset coefficients for all phases to be calculated and displayed
Note: The Mode, Voltage and Current edit boxes do not affect this function.
