Laureate™
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 Laureate 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 Laureate 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.
