Tonghui Insulation Resistance Meter TH2684/A - 1

TH2684 Features ■ 320^240 dot-matrix LCD ■ Powerful charging function ■ High speed measurement:100meas/sec ■ High measurement accuracy:±2% (< 1TQ ) ■ Contact detection function for capacitive components ■ Measurement range:TH2684 : 10kQ to 50TQ TH2684A: 10kQ to 100TQ ■ Ultra-low leakage current test: minimum current is 10pA, accuracy: 2% ±2pA ■ Measurement voltage:TH2684: 10V - 500V, dual-output TH2684A:10V-1000V,single-output ■ Dual outputs (precharge voltage output and test voltage output) can be set. ■ The precharge voltage output can be set to follow the test voltage output and can be finely adjusted on test voltage. Also the precharge voltage can be set to work in independent mode. ■ When the test current is less than 10nA, the internal input impedance can be selected between 10kQ and 1MQ to ensure rapid and accurate test. ■ TH2684 charge current:2mA , 25mA, 200mA selectable TH2684A charge current:2mA , 25mA , 100mA selectable ■ 7 current ranges, manual or auto range mode ■ 4-bin comparison function ■ Programmable sequence test mode ■ R-T and I-T Curve test and display mode ■ Auto store setup parameters ■ Screen hardcopy to be saved as BMP file to a U disk ■ Automatically upgrade firmware by a U disk ■ Selectable Chinese and English operation interfaces ■ Achieve automatic test system by Handler interface ■ Achieve remote control by RS232C and USB Device interface ■ Support scanning interface for mass tests 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 10kQ input impedance can be used; if the current is below 10nA, you can choose 10kQ or 1MQ 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.
