1 Phase / 3 Phase Data Logger/Recorder
The Amprobe DM-III MultiTest works with single and three phase systems (Y and delta). It detects and records voltage anomalies, sags and surges. The instrument was designed to perform the following tests:
- LowΩ: Continuity Test of Protection and Equalizing conductors with a test higher than 200mA and open circuit voltage ranging from 4V to 24V.
- Insulation Test: Measurement of insulation resistance with DC test voltage 50V, 100V, 250V, 500V or 1000V.
 : Indication of phase rotation sequence- Ground Test: Measurement of ground resistance and resistivity using earth rods.
