8.5.1
Overall Calibration Procedure
The overall procedure of calibrations is described by using an example of voltage calibration according to
Figure 8-2 Calibration Procedure (1).
1. Enter the calibration mode by CAL1.
2. When executing all the calibrations, initialize calibration data only once by XINI
at the start of the calibrations.
3. When executing voltage calibration, make connection for voltage calibration in
reference to Figure 8-1 (a) Checking and calibrating voltage source measurement
of Figure 8-1 in Section 8.3, "Connections."
4. Press OPR to set the output status to Operate in the calibration mode.
5. Execute the voltage source and limiter calibration and the voltage measurement
calibration according to Figure 8-3 Calibration Procedure (2) and Figure 8-4 Cal-
ibration Procedure (3) respectively.
6. Press SBY to set the output status to Standby.
7. Store the calibration data to the non-volatile memory by XWR.
8. Finish the calibration mode by CAL0.

3. Enter the DMM data input mode by XDAT.
4. Set the DMM read value by XD data.
5. Move to the full-scale calibration mode by XNXT.
6. Set the DMM read value by XD data.
7. Finish the DMM data input mode by XNXT.
8. Move to the zero calibration check mode by XADJ.
9. Check the zero calibration value.
10. Move to the full-scale calibration check mode by XNXT.
11. Check the full-scale calibration value.
12. Move to the next step.
When changing the voltage calibration mode:
XNXT
When moving to the voltage measurement calibration: XVM
