DC Current Metering

The PRO Series meters function as analyzers for direct current (DC) systems as well. This application is based on the PRO models featuring 40mA inputs (the HACS model), using Hall Effect Sensors.
currents up to 4,000A DC.

DC Voltage Metering

The PRO meter can withstand up to 820V DC direct measurement. From 820V DC a Voltage Ratio Module (VRM) must be used, as described in the quick-start guide, available for download.
The VRM can withstand and measure voltages up to 1,500V DC.
