The AT686A high-voltage insulation resistance tester is an intelligent testing instrument controlled by a high-performance ARM microprocessor. It features a color LCD display and is the first to offer arbitrary voltage output from 50V to 5000V, meeting the most demanding requirements. The insulation resistance measurement range reaches: 100k - 100GΩ, with a display of 20,000 counts. The test speed can reach 100 readings/second, providing an optimal solution for automated production with ultra-high-speed testing.
The timer supports count-up and countdown functions.
The instrument features a sorting function with audible alarm settings, and can be equipped with a Handler interface for use in automatic sorting systems to complete fully automated production line testing. It can also be equipped with an RS232C interface for remote control and data acquisition and analysis. The standard USB interface allows for convenient instrument upgrades.
The computer remote control commands are compatible with SCPI (Standard Commands for Programmable Instruments), enabling efficient remote control and data acquisition functionality.
