All single display units are 3½ digits and may be ordered with optional features such as analog outputs, including 1-5 VDC, 0-1 mADC or 4-20 mADC. Direct input voltages of up to 600 volts AC and currents as high as 10 amps AC are standard and accuracy to 0.25% of full-scale are common. Watt, var, power factor and phase angle units are available in single phase, three phase, three wire and three phase, four wire options.
