Meters are quickly mounted through a circular hole and secured with a nut (included).

Decimal point placement may be selected through jumper links, and scaling and calibration may be adjusted by potentiometers. Rectangular models include a rubber seal that fits between the meter and mounting panel to provide splashproof protection, and utilize soldered wire connections. The EMT 1900 uses an internal sensor, if external temperatures are needed use optional NTC-PROBE-1900.
