Performance characteristics and application range of insulation resistance tester

TH2684A Insulation Resistance Tester Brief Introduction:

TH2684 high-precision insulation resistance tester is an intelligent measuring instrument that can quickly measure the insulation performance of electronic components, dielectric materials, equipment, wires and cables, etc. It uses a large-size LCD and a user-friendly menu layout, allowing users to operate the instrument more conveniently.

The switchable input internal resistance technology and built-in dual voltage output are adopted, and the pre-charging and contact check functions are supported, so that the instrument can realize the fast general technical parameter test of the capacitor IR.

TH2684 can be programmed by the user for test steps, up to 18 steps. For example, the user can program charging, waiting, testing, discharging, etc., and each step can last up to 100s.

TH2684 is equipped with RS232, USB DEVICE, scanning port, Handler and other interfaces. The Handler interface provides convenience for the realization of automatic test system. The scanning port provides convenience for the testing of a large number of components. Users can also use a scanner to speed up the testing of components.

■ TH2684 has two voltage output functions. The pre-charge voltage output and the test voltage output are set separately. The pre-charge voltage output can be set to follow the test voltage change and can be fine-tuned on this basis. In addition, it can also be set to an independent voltage output mode.
