Used as a DC ammeter, this Digital Panel Meter (DPM) model provides a full-scale readout of ±20,000 counts (selectable fixed zero or active least significant digit) and four full-scale direct-reading current ranges/resolutions (see Specifications).  The 5.000-A range measures the IR drop across a built-in 10-mΩ current shunt.  Accuracy is 99.99% of full scale ± 1 count.

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

All current 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 separately selected to be either filtered or unfiltered.  See Digital Panel Meters (DPM’s) for a full description of these and other standard DPM features.

2000 Series options applying to the DC current meter include

	Isolated Relay Outputs
	Isolated Analog Output
	RS232 or RS485 Interface
	BCD Digital Interface
	Low AC/DC Power
