Used as a direct-reading DC voltmeter, this Digital Panel Meter (DPM) model provides a full-scale readout of ±20,000 counts (selectable fixed zero or active least significant digit) and five full-scale voltage ranges/resolutions (see Specifications). Accuracy is 99.99% of full scale ± 1 count. To minimize the load on the voltage signal, a high input impedance is provided (up to 1 G? for the 200.00-mV and 2.000-V ranges). The maximum voltage which can be applied on the 20, 200, and 660 V-DC range is 660 V-AC.

The model-numbering system is given in the Specifications table, below.

The meter can be used with external current shunts (as shown in the figure), which typically produce 50 mV or 100 mV at their rated maximum current. Scaling from millivolts to amperes for a specific shunt is easily accomplished from the front panel of the meter. The scalable readout is five full digits up to ±99,999 counts. Since the voltage signal from a current shunt can be noisy, the meter provides a selectable, adaptive moving average digital filter (see Digital Panel Meters (DPM’s).

All voltage ranges are calibrated at the factory, with calibration factors for each range stored in internal EEPROM. This allows ranges to be changed in the field without having to recalibrate the meter.

As with all 2000 Series DPM’s, the peak value of the input signal is automatically captured and may be displayed via front-panel push button or a control signal received at the rear connector (since the last meter reset). Data readings and outputs can be separay selected to be either filtered or unfiltered. See Digital Panel Meters (DPM’s) for a full description of these and other standard DPM features.
