Notes:
1. For Voltmeter and kilowatt meter without an external PT please use the
default PT Ratio of 110/110V.
2. Max. Value of power ratio for kW meter is 1000000.
Power Ratio = CT Ratio x PT Ratio.
Example: If user set CT as 9999 and then tries to set PT Ratio as 440kV
then PT Ratio will not set and meter will display FAIL.
96mm
3. For Ammeter if the value exceeds 9999A then the LED indication for kilo
will glow and meter will display
.
4. For Voltmeter if value becomes 1000V then LED indication for kilo will
glow and meter will display 1.000 on its display.
Operation and Instruction Manual
2.2 The panel meter is to be firmly fixed using the 4 transparent fixing clips
supplied with the meter.
Use 0.5 to 2.5mm2 cable for voltage terminals.
Use 3 to 6mm2 cable for current terminals.
