It directly replaces analog, signal-driven meters for current loops, ac/dc volts, amps, Watts, frequency and other signals capable of producing 5 mW or more. As an all-hardware device, it has no critical digital assets (CDA) as defined by NRC/NEI 10-04. It displays 4½ digits with 0.50% accuracy and resolution, and has a mean time between failure (CMTBF) more than 25 years. On-off alarm outputs, 4-20 mA retransmission and serial output are optional.
