PLZ-4WH
CC Mode Calibration (Calibration numbers 1, 2, and 3)
Connect a constant-voltage power supply to the load input terminals,
and apply 5 V. Set the power supply current to approximately +2 % to 5
% of the load device's rated current.
Press ENTER.
The load turns on automatically, and the offset calibration (CC (Low) Offset
Adjustment) screen appears.
CC(Low)

DAC REF : 0x0001
MON : 0x0001

Press or to set the cursor position of DAC REF, and then turn the
rotary knob so that the current flowing through the shunt resistor is
within ±0.1 % of the value corresponding to 10 % of the full scale value
(see the table of CC mode settings).
The measured value offset MON is set automatically.
Step B: Calibrate the offset value for the internal reference voltage for the
protection functions.
Press ENTER.
The offset calibration screen (CC (Low) Limit Offs Adjust) appears.
Press or to set the cursor position of DAC LIM, and then turn the
rotary knob so that the current flowing through the shunt resistor is
within ±0.1 % of the value corresponding to 10 % of the full scale value
(see the table of CC mode settings).
Press ENTER.
The load turns off automatically.
Step C: Calibrate the gain values of the internal reference voltage for
current settings and of the measured values.
Connect a shunt resistor that matches the value corresponding to 100 %
of the maximum low range value.
Press ENTER.
The load turns on automatically, and the gain calibration screen (CC (Low) Gain
Adjustment) appears.
Press or to set the cursor position of DAC REF, and then turn the
rotary knob so that the current flowing through the shunt resistor is
within ±0.1 % of the value corresponding to 100 % of the full scale value
(see the table of CC mode settings).
The measured value gain MON is set automatically.
Step D: Calibrate the gain value for the internal reference voltage for the
protection function settings.
Press ENTER.
The gain calibration screen (CC (Low) Limit Gain Adjust) appears.
Press or to set the cursor position of DAC LIM, and then turn the
rotary knob so that the current flowing through the shunt resistor is
