These meters are full color for easy viewing. Standard Amp scales will have a red bar at 80% to 100% scale. Mounting hardware included.
Select volt meter ranges for the highest DC voltage. Example: Any power supply rated for 200V or less can use the 200V meter. The best practice is to choose a voltage closest to the rectifier rating. A 12V power supply should use a 15V standard meter.
Standard meters operate at 50mVDC. Choose a standard scale.
Standard input is 50mVDC. Other inputs may be possible. Make sure you supply the calibration info in the custom option when ordering. Supply amps or volts as necessary. If a custom mV is required for an amp meter then supply both mV and amp scale.
Faceplate dimensions are 5.0625 in x 3.9375 in.
