The picture shows the DC voltage meter wiring method circuit. The voltage meter is used to measure the voltage of electrical line voltage. When measuring it could connect the voltage meter directly to the circuit, which is shown in the picture. When wiring it should be noted that the positive and negative polar of the voltage meter and the wire's positive and negative polar should be corresponding. It the voltage meter measurement mechanism's internal resistor R is not large enough, and also the measurement voltage is a little higher, in this case it should add a serial resistor R to reduce the meter mechanism's voltage. The resistor in this circuit is also called voltage doubler.
