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

The ZC5990D loudspeaker F0 tester is a special test equipment with very good test accuracy, accuracy and stability. When the test frequency range is set to 400Hz, the resolution can reach 1Hz. The smaller the test frequency range, the higher the resolution, which is very beneficial to the F0 test of the low frequency loudspeaker (box). A 4.3-inch color LCD screen is used, which can directly display the F0 curve of the speaker.

Performance characteristics

High accuracy, the frequency error of the test signal ≤0.01%
High precision, the test error when five times of retracement is ≤0.1%±1Hz (±1 word)
The test frequency range is wide, 20Hz~20kHz when testing the full frequency range
Fast test speed, can directly display F0 curve
Convenient operation and clear display
Exquisite structure, easy to carry
