A compact loop powered indicator giving an accurate, zero corrected indication of 4-20mA loop current. Calibration is by two multi-turn potentiometers which allow sensitive adjustment of the instrument. The DPM 342 features an integral snap-in bezel, making installation easy. The module’s LED back-lighting ensures a clear display, even under low light conditions. No soldering is required. Connection to the current loop is via two screw terminals. The correct decimal point is selected via a jumper link.
