ZC2516BS low resistance tester

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

ZC9900 series AC and DC withstand voltage insulation tester is a high-performance tester using brand new technology. Its unique current protection function and high-precision output voltage enable the instrument to provide more accurate and faster tests while ensuring safety. The maximum 8 channels of withstand voltage output can better meet the all-round requirements of customers! ZC9900 series withstand voltage testers are mainly used for the safety performance testing of instruments, equipment and components!

Performance characteristics

ZC9901 is a single channel high voltage tester
ZC9904 is a 4-channel high-voltage scanning tester
ZC9908 is an 8-channel high-pressure scan tester
Test function AC/DC/IR
Display: large LCD display with a display resolution of 240x64
AC voltage output: 50V-5kV, AC current: 30mA
DC voltage output: 50V-6KV, DC current: 10mA
Wide measuring range of insulation resistance: 1MΩ-50GΩ
Ground connectivity test GC (optional function)
Programmable leakage current upper and lower limit setting
IR, DC test fast discharge function
99 steps to store data
Good electric shock protection function: when the leakage current to the ground is greater than 0.5mA, the ground failure protection function is quickly triggered to effectively protect the external leakage and avoid accidents.
Standard RS-232 standard communication interface, optional GPIB
