CC Mode Calibration (Calibration numbers 1, 2, and 3)
Perform calibration on the Low, Mid, and then High range. For each item, start calibration at
step A. Be sure to calibrate both offset and gain.
■
CC mode settings
The current settings for each model are listed below.
Calibrating the low range
■
Step A: Calibrate the offset values of the internal reference voltage for
current settings and of the measured values.
1
Connect a shunt resistor or ammeter that matches the value
corresponding to 10 % of the full scale low range value.
2
Press MENU (SHIFT+SET/VSET).
The menu screen appears.
3
Use to select “3. Calibration,” and then press ENTER.
4
Use and to select “1. CC(Low).”

Memo
When calibrating multiple PLZ-4WHs of the same model operating in parallel operation, multiply the
current setting by the number of units.
Example: Three PLZ334WHs in parallel operation using CC (Mid) gain
(1.65 A±1.65 mA) x3=4.95 A±4.95 mA
When calibrating a setup that includes a PLZ2004WHB, multiply the rated power [kW]/1 [kW] to the current
setting for the PLZ1004WH.
Example: One PLZ1004WH (1 kW) and two PLZ2004WHBs (2kW) using CC (High) gain
Because the rated power is 5 kW, the current setting is (50 A±50 mA) x5=250 A±250 mA
Use shunt resistors and a regulated DC power supply whose rated currents are higher than the maximum
current that flows during calibration.
