Comprehensive test and measurement service provider-Shenzhen Weike Electronic Technology Co.
■ Model TH2684 high precision insulation resistance tester is an intelligent measuring instrument that can quickly measure the insulation performance of electronic components, dielectric materials, equipment and wires and cables. It adopts large-size liquid crystal and humanized menu layout, so that users can operate the instrument more conveniently.
■ The use of switchable input resistance technology and built-in dual-voltage outputs, support for pre-charging, and contact checking function, so that the instrument can realize the capacitance of the IR rapid general technical parameters of the test.
■ The TH2684 can be user-programmed with up to 18 test steps. For example, user programmable charging, waiting, testing, discharging, etc., with each step lasting up to 100s.
■ The TH2684 comes standard with RS232, USB DEVICE and Handler interfaces. Among them, Handler interface provides convenience for realizing automatic test system. The scanning port provides a convenient way to test a large number of components. Users can also be equipped with a scanner to speed up component testing.
■ TH2684 has two voltage output functions, pre-charge voltage output and test voltage output are set separately. Pre-charge voltage output can be set to follow the change of test voltage and can be fine-tuned on this basis, in addition, it can also be set to independent voltage output mode.
