The AT686 high-voltage insulation resistance tester is an intelligent testing instrument controlled by a high-performance ARM microprocessor. With a color LCD display, it features the industry-first 50V~2500V variable voltage output to meet the most demanding requirements. The insulation resistance measurement range reaches 100kΩ-10GΩ, with a display of 20,000 counts. The test speed can reach 100 tests/second, providing an ideal solution for automated production.
The timer supports both count-up and count-down functions.
The instrument features sorting function with audible alarm settings, and can be equipped with a Handler interface for automated sorting systems to achieve fully automated production line testing. It can also be equipped with an RS232C interface for remote control and data collection and analysis. The standard USB interface facilitates easy instrument firmware upgrades.
The computer remote control commands are compatible with SCPI (Standard Command for Programmable Instruments), enabling efficient remote control and data acquisition.
