Press ENTER.
The load turns on automatically, and the offset calibration (CV 4V Offset Adjustment)
screen appears.
4
Press or to set the cursor position of DAC REF, and then turn the
rotary knob so that the input voltage is within ±0.05 % of the value
corresponding to 10 % of the full scale value (see the table of CV mode
settings).
The measured value offset MON is set automatically.
■
Step F: Calibrate the offset value for the internal reference voltage for the
protection functions.
5
Press ENTER.
The offset calibration screen (CV 4 V Limit Offs Adjust) appears.
6
Press or to set the cursor position of DAC LIM, and then turn the
rotary knob so that the input voltage is within ±0.05 % of the value
corresponding to 10 % of the full scale value (see the table of CV mode
settings).
7
Press ENTER.
The load turns off automatically.
■
Step G: Calibrate the gain values of the internal reference voltage for
voltage settings and of the measured values.
8
Press ENTER.
The load turns on automatically, and the gain calibration (CV 4V Gain Adjustment)
screen appears.
9
Press or to set the cursor position of DAC REF, and then turn the
rotary knob so that the input voltage is within ±0.05 % of the value
corresponding to 100 % of the full scale value (see the table of CV mode
settings).
The measured value gain MON is set automatically.
■
Step H: Calibrate the gain value for the internal reference voltage for the
protection function settings.
10
Press ENTER.
The gain calibration screen (CV 4 V Limit Gain Adjust) appears.
11
Press or to set the cursor position of DAC REF, and then turn the
rotary knob so that the input voltage is within ±0.05 % of the value
corresponding to 100 % of the full scale value (see the table of CV mode
settings).
12
Press ENTER.
The load turns off automatically.
The calibration of the low range voltage values is complete.
