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

As an upgraded model of the original ZC1681 series, the ZC5820 multi-channel speaker life tester has changed the original MCU control to an industrial computer, providing a basis for realizing instant communication, remote control and other intelligent operations. This is a multi-channel, multi-function power test equipment. The user can store the test signal in the computer and play it through a professional sound card, and its stability is greatly improved; the parameters of the signal after power amplification are guaranteed to be consistent with the original signal. Each output has a separate measurement system, which can measure the actual voltage, current, DC resistance, temperature rise, product status and other data of each channel. The biggest highlight of this product is the data storage and processing, as well as the visual graphical interface, which can display the current status more conveniently and intuitively, save all the data, and facilitate the analysis of the product after the test.

Scope of application

Mobile phone speakers, receivers, MP3, tablet computers, laptop speakers, low-power TV speakers, etc.

Performance characteristics

Signal source: built-in sine wave generator and frequency sweep controller, can be stored in various formats of audio files
Two sets of voltages can be arbitrarily set up to 20 channels at the same time to monitor, automatically record and display voltage/current/DCR/temperature rise/test time and status
The test voltage is automatically corrected, the accuracy can reach ≤1%, and the display is 0.001V
8-inch LCD panel, richer display content, larger fonts, easy to observe
Interface: front panel signal data input interface (USB), rear panel USB, LAN network port
Temperature rise measurement range: 0~200℃, measurement accuracy ≤5%±1℃
Support multiple working modes: continuous, intermittent, and debugging. Among them, the minimum interval supports 0.5s, and the voltage can still be accurately measured
