6.2.5 Calibration Procedure
For items (1) through (10), calibrate both the range offset and maximum in the CC, CR, CV, and CP modes. The values
in the upper field of the display are pre-calibration values and, therefore, differ from the measurements obtained on the
external equipment.
For items (11) through (16), calibrate both the ammeter and voltmeter. (Since the power meter indicates the product of
the indicated values on the ammeter and voltmeter, no calibration is necessary.)
The table below lists calibration references for PLZ-3WH series electronic load units.
Table 6.2-2
To select a calibration item, use the [ ] and [ ] keys. For the selected item, the load is automatically turned off to
ensure safety. To start the calibration, press the [LOAD] switch. The voltage and current actually applied to the load
terminal, and the power, are indicated in the upper field of the display. The selected calibration item and presently
calibrated value are indicated in the lower field. Take note of the present calibrated value and then execute the
calibration. Whenever setting the calibration reference for one item, select the next item with the [ ] and [ ] keys, or
press the [ESC] key to return to the Configuration Menu.
Each item is calibrated using the following procedure (the number on the left end shows the item number).
