The ACE provides accurate digital metering for AC Volts, Amps, Frequency and Kilowatts. Low / High Voltage and Low / High Frequency alarms are easily set. When activated, the built-in 85 dB alarm will sound, the display will flash the out of limit condition, and the optional generator cut-out can be used to turn off the faulty generator. Five levels of back lighting can be selected and all set-up, calibration and alarm values are saved to non-volatile memory.
