AT68208 Multi-Channel Insulation Resistance Tester

The AT6820x Multi-Channel Insulation Resistance Tester is a fully automatic, real-time testing benchtop instrument controlled by a high-performance ARM microprocessor. It features a full-color LCD display and a full numeric keypad, powered by the ONMEAS instrument operating system, making the display clearer and operation more convenient.

The instrument features a built-in 1V~1000V voltage source with 1V resolution, fully programmable output. It offers 2% basic accuracy for insulation resistance measurement, with a test range up to 10GΩ. It provides 9999 counts and a measurement speed of up to 30 readings/second.

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

The built-in comparator can output comparison results via the Handler interface. The instrument comes standard with USB-232, RS-232, and RS-485 interfaces, 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.
