Selling points

The EV Tester from Power Probe is designed for EV technicians. This compact ECE-R100-compliant multimeter combines the three essential EV testing tools: CATIII/1000V & CATIV/600V-rated voltmeter, 1,000V insulation tester, and true milliohm meter.

Features and benefits

Bonding test (Kelvin 4-wire type) up to 1A: Verifies true low resistance connections under load, especially important in high voltage circuit connections.
Insulation resistance test up to 1,000 VDC and 200GΩ with PI, DAR Calculation: Extremely accurate low-range resistance testing (see Bonding Test).
CATIII/1,000V and CATIV/600V Rated: Correct range and safety rating for EV servicing.

Application

Testing high voltage cable connections and similar by verifying true low resistance connections under load (true milliohm meter (4-wire) for precise measurement (down to .0001mΩ)) and two wire resistance test up to 40kΩ
Voltage leakage and damage testing on high voltage circuits (like motor windings) via insulation test (up to 1,000VDC 200GΩ)
Test capacitors up to 1,000μF
Wire length calculator to determine wire length by gauge, great for testing motor windings
Basic voltage measurement up to 1,000V

Origin

This tool came from the desire to supply technicians with a single tool for EV servicing rather than three tools that all EV technicians need when working with EV systems.

Manufacturing/engineering specifications

The EVTEST is made in Taiwan from various plastics and rubbers. It features a color TFT screen and a rugged housing. The tool weighs 1.4 lbs.

Storage and display

The tool is shipped in a cardboard box, packaged nicely in a branded Power Probe canvas bag with all included accessories. There is one EV Test per package. The tool displays well on a shelf or toolboxes next to other electrical equipment and testing tools.
