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
