The AT682 is a smart test instrument controlled by a high-performance microprocessor. In applications where an external voltage source is not required, the AT682 delivers excellent measurement performance at an affordable price.
It features a built-in 1V~1000V arbitrary voltage output to meet any demanding requirement.
Six-range testing enables an insulation resistance measurement range of: 10k-1TΩ (104~1012Ω), with a display of 9999 counts. The test speed can reach up to 55 times/second, providing an optimal solution for automated production.
The 2010 upgraded version features an improved sampling circuit with a response time that surpasses analog meters.
The instrument features a sorting function with audible alarm settings, and can be equipped with a Handler interface for high-speed sorting systems to perform fully automated production line testing. The built-in RS232C interface supports computer remote control commands compatible with SCPI (Standard Command for Programmable Instruments), enabling efficient remote control and data acquisition.
