AT68216 Multi-Channel Insulation Resistance Tester

The AT682xx series multi-channel insulation resistance tester is a compact benchtop instrument controlled by a high-performance ARM microprocessor for fully automatic real-time detection. It features a full-color LCD display and a full numeric keypad, paired with the Onmeas Instrument Operating System, making the display clearer and operation more convenient.

The instrument is equipped with a built-in 1V~1000V programmable voltage source with 1V resolution. It offers 2% insulation resistance accuracy with a measurement range up to 10GΩ. With 9999 counts and a measurement speed of up to 30 times/second, it ensures efficient testing.

The instrument can store 10 groups of settings internally, and an external USB drive can also store 10 groups, making it easy to recall different specifications.

The instrument features a built-in comparator, and comparator results can be output via the Handler interface. Standard interfaces include USB-232, RS-232, and RS-485, supporting SCPI (Standard Commands for Programmable Instruments) and Modbus RTU protocols for communication with computers, PLCs, or WINCE devices, enabling efficient remote control and data acquisition.
