Key Voltmeter Characteristics

• High Voltage Isolation for Operator Safety: Tested to 1 kV steady-state/15 kV transient voltage levels (designed for higher voltage level isolation). Meets the IEC Standard for Category IV environments.

• Analog Pre-Processing & Digital Signal Processing (DSP): Accurate determination of On/Off pair values. Voltmeter does not saturate even with superimposed AC signals (up to 120V) and/or inductive spikes (up to 2 kV) appearing at the input terminals.

• Fast Response Channels (Ranges) Available: 80ms response time in combination with high input impedance values (up to 400 MΩ). Accurate On/Off pair readings during fast cycle current interruption, even under high source resistance conditions.
