These meters are full color for easy viewing. Standard Amp scales will have a red bar at 80% to 100% scale. Mounting hardware included.
Volt Meters:
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.
Amp Meters:
Standard meters operate at 50mVDC. Choose a standard scale.
Custom Calibration:
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.
