TES-1601 Auto-Ranging Insulation Tester

Description

The TES-1601 is a digital, auto-ranging insulation tester from TES Electrical Electronic Corp. It is designed for high-impedance insulation testing and provides a digital readout with an analog bar indicator. The device features an auto-range function for the megaohm setting and can test insulation at rated voltages into a 1mA load.

Key Features

Insulation testing: The device can test insulation resistance up to 4000 MΩ at three different terminal voltages: 250V, 500V, and 1000V.

Auto-ranging: The tester automatically selects the correct range for megaohm resistance measurements, simplifying the testing process.

Dual display: The 3-3/4 digital readout is combined with a 50-segment analog bar graph for easy interpretation of measurements.

Continuity testing: It features a continuity function with a 200mA short-circuit current and a beeper that activates when resistance is less than 40Ω.

Voltage measurement: It is capable of measuring AC voltage up to 600V.

Data hold: A data hold function automatically locks the test result on the screen after the test button is released.

Power-lock switch: For insulation tests lasting up to three minutes, a power-lock switch can be used, and the device will automatically power off afterward.

Auto-zero adjustment: This feature ensures accuracy by automatically resetting the measurement to zero.

Safety standards: The tester is designed to comply with IEC61557 international safety standards.
