The Laureate DC volt meter provides a full-scale volt meter display of ±20,000 counts and five full-scale ranges from ±200.00 mV with 10 mV resolution to ±600.0 V with 100 mV resolution. The ±200.00 mV and ±2.000 V ranges provide an 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 600 Vdc ranges is 600 Vac.
The Laureate True AC RMS volt meter offers a full-scale volt meter display of 0 to 20,000 counts and five full-scale ranges from 200.00 mV with 10 mV resolution to 600.0 V with 100 mV resolution. The 200.00 mV and 2.000 V ranges provide an input impedance of 22 Mohm so as to minimize the load on the voltage signal. The maximum voltage which can be applied on the 20, 200 and 600 Vac ranges is 600 Vac.
The Laureate True AC RMS volt meter is suited for AC volt meter applications where there is considerable distortion of current waveforms from nonlinear loading. The input is AC coupled to read only the AC component, such as ripple on a power supply. The volt meter uses precision circuitry to compute the root-mean-square of complex waveforms from 10 Hz to 10 kHz. Spikes up to 2.4 times the maximum of each voltage range are accurately measured. This provides a crest factor (Vp / Vrms) of 240 for a signal amplitude of 1% of full scale voltage, decreasing to 2.4 at 100% of full scale. High common mode rejection allows stable readings with current shunts located on the high side of the line.
