5. Press the or CURSOR key to select DAC REF, and turn the rotary
knob. Set the current
fl owing through the shunt resistor within
±
0.1 % of
the value corresponding to 10 % of the range full scale.
MON is automatically set as the offset of the measured value.
See Fig. 8-3 for the current settings of each model.
The calibration for this item is complete. Continue to step B.
Step B: Calibration of the offset of the internal reference voltage for
protection function setting
6. Press the ENTER key.
The offset calibration (CC (Low) Limit Offs Adjust) screen appears.
7. Press the or CURSOR key to select DAC LIM, and turn the rotary
knob. Set the current
fl owing through the shunt resistor within
±
0.1 % of
the value corresponding to 10 % of the range full scale.
See Table 8-3 for the current settings of each model.
8. Press the ENTER key.
The load is automatically turned off.
The calibration for this item is complete. Continue to step C.
Step C: Calibration of the gains of internal reference voltage for out-
put setting and measured value
9. Connect a shunt resistor that matches the value corresponding to 100
% of the low range full scale.
10. Press the ENTER key.
The load automatically turns on, and the gain calibration (CC (Low) Gain
Adjustment) screen appears.
11. Press the or CURSOR key to select DAC REF, and turn the rotary
knob. Set the current fl owing through the shunt resistor within 0.1 % of
the value corresponding to 100 % of the range full scale.
MON is automatically set as the gain of the measured value.
See Table 8-3 for the current settings of each model.
The calibration for this item is complete. Continue to step D.
