Offset/Full-Scale Calibration of Output Current Monitor（ZX Series Type-LAN）
１．Perform load with only the shunt resistor.
Disconnect the load wires and the remote sensing wires
.
Connect the shunt to the output terminal. Connect the
digital multimeter to the voltage terminal located on the
shunt.
Connect the digital multimeter to the external control
connectors number 3 and 4. (Current Monitor Terminal)
Turn the POWER switch ON and OUTPUT OFF in
advance.
２ ． Press the FUNC. key and change the top Number
Display to Settings Item 13 with the VOLTAGE dial.
３．Turn the CURRENT dial and set the current value to 0
(Linearity Compensation: OFF).
４．Press the FUNC. key again to finalize settings.
５．Press the PRESET key ① and set to “1.00V” with
the VOLTAGE dial ② and “40.00A～160.0A” （※）
with the CURRENT dial ③.
※For 400LN/LAN set to “40.00A”
For 800LN/LAN set to “80.00Ａ”
For 1600LN/LAN set to “160.0A”
６．Press the PRESET key ①
７. Set the load switch S1 to OPEN.
