AT69210 Multi-Channel Parallel Insulation Resistance Tester

The AT69210 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 AT69210 features fully parallel measurement. In parallel mode, all channels start measurement simultaneously. Each channel can independently set its test voltage and range to suit different DUT requirements. It is equipped with a built-in 10V~1000V programmable voltage source with 1V resolution. The instrument offers 2% insulation resistance accuracy with a measurement range up to 20GΩ. The test speed can reach 30 times/second.

The AT69210 features contact check and short circuit detection functions. It includes charging timer (0.1s-60s), measurement timer (0.1s-999.9s), and discharging timer (0.1s-60s) functions. It can store 10 groups of settings internally, and an external USB drive can also store 10 groups, making it easy to recall different specifications. Built-in comparator.

The AT69210 comes standard with LAN interface, RS-232 interface, and RS-485 interface, using 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.
