Introduction TH2827 series is a new precision LCR meter with various functions and a higher test frequency. With small size and portable appearance, it is convenient for use on the shelves. This instrument has a basic accuracy of 0.05%, maximum test frequency of 1MHz and resolution of 10 mHz. It is easy to operate with a 4.3-inch LCD screen as well as selectable Chinese and English operation interfaces. Integrated transformer test function and balance test function greatly improve the test efficiency. The instrument is also provided with multiple interfaces which can meet various requirements of the automatic sorting test, data transmission and storage. Auto balancing bridge method with the widest impedance measurement range 4-terminal pair configuration to eliminate electromagnetic couple of test leads Basic accuracy: 0.05 %( TH2828/TH2828S), 0.1 %( TH2828A) Maximum test frequency up to 1 MHz AC test signal programmable to 20V (optional) Maximum measurement speed up to 30 meas/sec 6-digit display resolution 22 parameter combinations available Features ? 4.3-inch TFT LCD display ?
