Autoranging Insulation Resistance Tester

The TES 3660 is a handheld instrument that automatically selects the correct measurement range for insulation resistance tests. It is built for electricians and maintenance technicians who need to verify the integrity of wiring, motors and transformers. The meter arrives new in a single retail box with a three-year parts and one-year labour warranty.

Suited for routine insulation checks.

This meter suits professionals performing periodic insulation resistance measurements on low- and medium-voltage installations. It is not intended for users who require high-voltage proof testing, advanced diagnostic functions such as polarisation index or dielectric absorption ratio, or data logging capabilities.

Autoranging measurement capability

The defining feature is the autoranging function, which removes the need to manually switch ranges during a test and reduces the chance of operator error. This single capability determines whether the instrument matches the workflow of the technician using it.
