Diagnose Common Electrical Issues with the Amprobe DM-III

Amprobe DM-III Multitest Power Quality RecorderThe Amprobe DM-III Multitest Power Quality Recorder evaluates power quality characteristics of single and poly-phase systems up to 600 Volts AC, and also has the capability to measure insulation and ground resistance. This versatile tool is essential in diagnosing common electrical issues.

Insulation Tester Functions:

− Tests insulation integrity of wires, cables, transformers & electrical motors

− Selectable test voltages up to 1000 V

− Programmable timer to perform the Dielectric Absorption Ratio Test

− Sensitive Ohmmeter for checking resistance of motor windings

− Selectable polarization of ohmmeter for checking grounding continuity

− Automatic voltmeter protects against misuse on hazardous energized systems

Ground Resistance & Resistivity Functions:

− Three measuring modes:

  • 2 point continuity/resistance test
  • 3 point Fall of Potential test
  • 4 point Earth Resistivity measurement

− Automatic voltage measurement prevents false measurements

− Automatically applies three testing frequencies for the most accurate readings

− Detects faulty test conditions such as poor soil conditions and input noise

Phase Sequence:

− Phase sequence indication

− Frequency measurement

− Phase-to-Phase voltage measurement
