8-12 Maintenance and Calibration PLZ-4W
4. Press the or CURSOR key to select DAC REF, and turn the rotary
knob. Monitor the input voltage on an external voltmeter, and set the
input voltage within 0.05 % of the value corresponding to 10 % of the
range full scale.
MON is automatically set as the offset of the measured value.
See Table 8-5 and set the input voltage.
The calibration for this item is complete. Continue to step F.
Step F: Calibration of the offset of the internal reference voltage for
protection function setting
5.
Press the ENTER key.
The offset calibration (CV 15 V Limit Offs Adjust) screen appears.
6.
Press the or CURSOR key to select DAC LIM, and turn the rotary knob.
Monitor the input voltage on an external voltmeter, and set the input voltage
within
 0.05 % of the value corresponding to 10 % of the range full scale.
See Table 8-5 and set the input voltage.
7.
Press the ENTER key.
The load is automatically turned off.
The calibration for this item is complete. Continue to step G.
Step G: Calibration of the gains of internal reference voltage for out-
put setting and measured value
8.
Press the ENTER key.
The load automatically turns on, and the gain calibration (CV 15 V Gain
Adjustment) screen appears.
9.
Press the or CURSOR key to select DAC REF, and turn the rotary knob.
Monitor the input voltage on an external voltmeter, and set the input voltage
within 0.05 % of the value corresponding to 100 % of the range full scale.
MON is automatically set as the gain of the measured value.
See Table 8-5 and set the input voltage.
The calibration for this item is complete. Continue to step H.
Step H: Calibration of the gain of the internal reference voltage for
protection function setting
10.
Press the ENTER key.
The gain calibration (CV 15V Limit Gain Adjust) screen appears.
11.
Press the or CURSOR key to select DAC REF, and turn the rotary knob.
Monitor the input voltage on an external voltmeter, and set the input voltage
within 0.05 % of the value corresponding to 100 % of the range full scale.
See Table 8-5 and set the input voltage.
12.
Press the ENTER key.
The load is automatically turned off.
The calibration of the low range voltage is complete.
