ZC2516S series intelligent low resistance tester is specially used to test various resistances. The 24 bit color 4.3 inch color LCD screen with touch function is simple in operation and fast in testing. It is suitable for various resistance design, inspection, quality control and production testing. This machine has three gear sorting function. In the sorting state, the resistance value or percentage value can be selected to display, and the resistance value can be judged as too large, too small or good according to the set value. At the same time, there is a sorting interface on the back panel of the instrument to enable the interface to start the signal and enable the instrument to measure. The test results are output from the interface on the back panel at the same time. Through this signal interface, the instrument can be connected to the component mechanical processing equipment for automatic testing. In addition, the machine has a USB interface and a Handler interface. The panel function can be completely controlled by the computer. The test results can also be sent back to the computer for saving through the USB interface or USB interface, or the data can be directly saved in a USB flash disk.

Brief introduction

ZC2818A high-frequency precision LCR digital bridge is an impedance measuring instrument with high measurement accuracy, wide test range, 6-bit test resolution, test frequency up to 300kHz, arbitrary programming at 0.01Hz steps, 10mV~2V signal level It can meet the requirements of production line quality assurance, incoming inspection and laboratory high-precision measurement. The HANDLER and RS232C interfaces provided by the instrument provide conditions for the instrument to be used in the automatic component sorting system, communicate with the computer and record the test process.

Flexible frequency response analysis

Since there are no ideal inductors, capacitors and resistors, in order to accurately evaluate the actual performance of an actual component in a certain frequency band, ZC2818A can accurately measure the frequency response of component parameters in any frequency band by virtue of its 10mHz resolution signal generation capability. The analysis, especially for the accurate measurement of the resonance impedance of low-frequency ceramic resonators with a wide impedance range.
