DPM 970
Digital AC Voltmeter Module
A 3 ? 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 auto-zero and suppression of d.c. offset voltage. The digital hold function 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.

SCALING
The value of the three scaling resistors RA1, RA2 and RB may be
altered in order to change the full scale reading (F.S.R.) of the meter
- see table. To ensure that the meter reads "000" with zero input
voltage/current, short circuit ACV and COM and adjust the ZERO
potentiometer. The meter will need re-calibration by adjusting the
CAL potentiometer.

NOTE
? Use inputs ACV and COM for measuring voltage.
? For measuring voltages above 500V RMS, external scaling
resistors must be used.

? Use inputs ACI and COM for measuring current.
? We recommend the use of a current transformer when
measuring in excess of 10 Amps. Consult current transformer
manufacturer ’s data for connections and recommendations.
Other scaling factors can be achieved via the correct selection of
RA1, RA2 and RB values.

* To ensure maximum accuracy, re-calibrate periodically.
** Maximum safe input voltage across the ACV and COM terminals is 500V RMS .
If voltages to be measured exceed 500V RMS , then fit scaling resistors
externally to the module.
