Step E: Calibrate the offset values of the internal reference voltage for
voltage settings and the measured values.
Use
and
to select "4. CV 65V."
Connect a CC power supply to the load input terminals, and supply 0.05
A. Set the power supply voltage to 66 V or greater.
Press ENTER.
The load turns on automatically, and the offset calibration (CV 65V Offset Adjustment)
screen appears.

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.
Press ENTER.
The offset calibration screen (CV 65 V Limit Offs Adjust) appears.
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).
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.
Press ENTER.
The load turns on automatically, and the gain calibration (CV 65V Gain Adjustment)
screen appears.
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.
Press ENTER.
The gain calibration screen (CV 65 V Limit Gain Adjust) appears.
