19mm (0.75“) Digit Height
Screw Terminal Connections
500V a.c. (2kV ) Full Scale Reading
Measures Voltage and Current
A 3 ½ digit LCD panel meter, featuring 19mm (0.75“) digit height and LED backlighting, the DPM 970 is a true RMS voltage and current meter with 500V a.c. (2kV) and 2mA full scale readings as standard. By changing the value of scaling resistors or adding a shunt, this module will measure most a.c. voltages and currents. The DPM 970 features digital hold function which freezes the last displayed reading. Calibration is achieved via two multi-turn potentiometers for offset and scale. Connection to the meter is via screw terminals. The module is housed in a robust carrier which can be bolted in place or panel mounted using the bezel, window and clips provided.
To measure in excess of 500V a.c., remove RA1, RA2 and RB1 from the meter and fit an external divider that will output 700mV for a 2kV input, e.g. series resistor 1.12 M Ω shunt resistor 390 Ω, link RA1 and RA2 on the meter. See scaling table in datasheet for suitable values for RA1,RA2 and RB1.
