Description

Micro Series DC voltage and current panel meters with a DC signal conditioner board combine high accuracy with high read rate and a wide range of isolated output options for computer interface and control. Accuracy is 99.99% of full scale ±1 count.

Used as a direct-reading DC voltmeter, the Micro DC meter provides a full-scale readout of ±20,000 counts and five full-scale voltage ranges from 200.00 mV with 10 mV resolution to 660.0 V with 100 mV resolution. The 200.00 mV and 2.000 V ranges provide a high input impedance of 1 Gohm so as to minimize the load on the voltage signal. The maximum voltage which can be applied on the 20, 200 and 660 Vdc ranges is 660 Vac.

Used as a DC ammeter, the Micro DC meter provides a full-scale readout of ±20,000 counts and four full-scale direct-reading current ranges from 2.0000 mA with 0.1 mA resolution to 5.000 A with 1 mA resolution. The 5.000 A range measures the IR drop across a built-in 10 mW current shunt.
