About Safety Ratings for Electrical Testing

Insulation Testers

Measure electrical resistance as an indication of insulation quality in equipment such as motors, generators, and switchgear.

Digital displays show a numeric reading on an LCD. Display count is an industry designation and not an actual value. For example, a 1,000-count tester shows numbers up to 999. A higher display count means the tester can give a more precise measurement.

Hand-Crank Insulation Testers

Turn the crank to generate voltage and measure electrical resistance as an indication of insulation quality in equipment such as motors, generators, and switchgear.

These testers have an analog display that works well for measuring rapidly changing resistance values because you can see the magnitude and rate of change more easily than on a digital display.
