The DPM 742-BL gives an accurate, zero adjusted indication of a 4-20mA current. Calibration is by two multi-turn potentiometers which allow sensitive adjustment of the instrument over a very wide range. Decimal points are jumper link selectable. A low drift bandgap reference circuit ensures accurate readings over a wide temperature range. LED back-lighting ensures excellent readability under low light conditions. Connection is via screw terminals. This module is supplied with a plastic mounting bezel.
