  Tips & Things to Remember in DC Amp Meter Wiring:

  • Use a DC amp meter for amp readings
  • Don’t allow incoming power to exceed the rated amperage (or voltage) of your meter – it may break the unit
  • Match the amp rating of the meter to the amp rating of the shunt bar
  • Match the millivolts (mv) of the meter to the millivolt (mv) rating of the shunt bar
  • The two wires between the meter and shunt bar need to be the same length
  • A wind turbine should be connected to a separate meter than the solar panel(s)
  • To test the amps or volts of your wind turbine or solar panel system with a handheld clamp on meter, you must use a DC model

Troubleshooting your DC Meter Issues:

  • If the needle on the meter is a negative reading, switch the sense wires between the meter and shunt bar
  • If the needle on your analog meter is not at zero when there isn’t incoming power, you can calibrate it by turning the screw on the front of the meter
  • If your digital handheld DC meter isn’t giving you an accurate reading, check the batteries in the unit

About DC Volt Meters:

  • The positive and negative inputs are typically not marked on the DC Volt Meter.  If you connect them to your battery and get a negative reading, simply swap the wires.
  • 12 Volt battery systems should use a 15 Volt meter; 48 Volt systems should use a 70-75 Volt meter.
