DC M2 OLED Digital Monitors
The M2 OLED Digital Monitor measures 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.
