* M-2A type series resistors that exceed 600V but are less than 750V are externally connected.
(Series connection, 1mA current consumption)
Note. Terminal cap is not included. (Optional)
Specify if required.
Remarks
Connection to Series Resistor :
Meters over 750V must be connected with the voltage division type series resistor specied in
the table above as shown in the gure on the right.
Note) M-6 series resistors must be connected to the earth using the G terminal.
The G terminal is only available on the M-6 series resistor.
There is no G terminal on other series resistors because the boxes are made of resin.
Meter Sensitivity
Standard DC voltmeter sensitivity is 1mA (1kΩ/V), but high-sensitivity meters can also be manufactured.
However, the 500V and 600V meters have a sensitivity of 500μA.
Note: Zero center meters and multiple-scale meters can also be manufactured.
