MI1 Tunable Voltmeter
Current Injection Testing (CIT) is used to measure earthing system performance. Our MI1 Tunable Voltmeter is a frequency selective voltmeter that measures off-power-system-frequency test voltages. During a CIT (even on an in-service earthing system) it can be used for Touch/Step voltage measurements, and EPR/Fall of Potential measurement.
Features:
- Lightweight, handheld form factor
- High noise rejection
- Accurately measures millivolt signals, with volts of noise
- GPS-referenced phase measurements are an optional extra
