Description
The Blue Sea Systems 1838 M2 AC Multimeter reads amps, volts and hertz on one OLED face, measuring two voltages and two circuits. Range runs 50 to 250 volts and up to 300 amps, and it supports programmable current transformer ratios so it can be matched to whatever CT is already installed.
Frequency matters more on a boat than it does ashore. Shore power at a marina is usually stable, but generator output drifts as load changes, and frequency wandering off 60 hertz is the first sign something is wrong with the set. High and low alarms are available on frequency as well as current and voltage.
The display auto-dims, so it does not blind you at night the way a fixed-brightness meter does, and the 92 dB alarm is adjustable. An isolated MOSFET relay is built in. The face measures 55 by 28 mm, input voltage is 7 to 70V DC, and power consumption runs between 0.3 and 1.0 watt. Browse more marine electrical meters.
