AC Multimeter with alarm. The M2 OLED Digital Monitors measure essential electrical system parameters with adjustable alarms and an auto-dimming display in a compact enclosure. The gasket creates a waterproof seal on the unit face. The M2 Monitors include a MOSFET External Circuit Relay (ECR) which can be used to control external circuits based on any value measured by the M2. The M2 External Circuit Relay is separate from and independent of the Internal Alarm function. Monitors AC Amps, Volts, Hzs on large, bright display. Supports programmable current transformer ratios. Accurately measure and monitor AC amperage, voltage and Hz. (measures 2 voltages and 2 circuits)
