High Voltage Insulation Resistance Test Meter 10V-1000V 100meas/Sec

TH2684/TH2684A High Speed Insulation Resitance Meter: 10V-1000V, 100meas/sec

1. Temperature Compensation: Some advanced DC Resistance Meters feature temperature compensation capabilities. They can automatically compensate for temperature variations that might affect the resistance measurement accuracy. The meters employ built-in temperature sensors or accept external temperature inputs to adjust the resistance readings accordingly.

Brief Introduction

TH2684/TH2684A High Precision IR Tester is an intelligent measurement instrument that is used for rapid measurements on IR properties of electronic parts and components, dielectric materials, equipments, cables,etc. Large LCD and user friendly menu provide you easier operation.

This instrument is especially designed for capacitor IR test TH2684/TH2684A can achieve rapid measurements through following methods:

1. Selectable internal input impedance: If the current is greater than 10nA, only 10k input impedance can be used; if the current is below 10nA, you can choose 10k or 1M impedance to test.

2. With the built-in dual voltage output, TH2684 can charge large capacitors. By dual voltage output, TH2684 is able to output a precharge voltage up to 500V, 200mA. In voltage follow mode, precharge voltage follow with the test voltage output and can be finely adjusted. Above features ensure the perfect charge of capacitive materials.

3. TH2684A can output a voltage of 1000V, 100mA to fully charge the capacitive material. In addition, user can program the sequence measurement steps (up to 18 steps) on TH2684/TH2684A. For instance,charge, wait, test, and discharge steps can be programmed.Each step can last up to 100s.

TH2684/TH2684A has a unique contact detection function. For capacitive material such as capacitors and cables, contact detection function can detect the contact of components under test. Moreover, this detection function will not increase any test time.

TH2684 equips with interfaces of RS232, USB DEVICE,SCANNING and Handler. Handler interface provide convenience for automatic test system; SCANNING interface is useful for mass measurement of components.User can use a scanner to speed measurement of components.
