TH2684 Insulation Resistance Meter

Features ■ 320×240 dot-matrix LCD ■ Powerful charging function ■ High speed measurement:100meas/sec ■ High measurement accuracy:±2% (<1TΩ ) ■ Contact detection function for capacitive components ■ Measurement range:TH2684 : 10kΩ to 50TΩ TH2684A: 10kΩ to 100TΩ ■ 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 10kΩ and 1MΩ 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
