AT688 Insulation Resistance Tester

The AT688 Insulation Resistance Tester is a smart test instrument controlled by a high-performance ARM microprocessor.

It features a color LCD display and innovative 1V~1000V arbitrary voltage output to meet any demanding requirement. Six-range testing enables an insulation resistance measurement range of 100kΩ~10TΩ with a display of 20,000 counts.

The test speed can reach up to 55 times/second, providing an optimal solution for automated production.

The timer supports both count-up and count-down timing functions.

The instrument features a sorting function with audible alarm settings, and can be equipped with a Handler interface for fully automated production line testing. It can also be configured with an RS232C interface for remote control and data collection & analysis.

The built-in USB interface allows for convenient instrument firmware upgrades.
