Product Introduction:

ZC3-EThe integrated digital rebound tester integrates all working modules into a protective cover, integrating display, port communication, button command control, and voice, greatly improving the stability and safety of the system.

The main functions of the product are:

Sampling, viewing, setting, online and other functions.

The entire machine consists of1600milliampere3.7vPowered by lithium-ion batteries, using128 x 32Dot matrix LCD display, with sensors directly plugged into the motherboard and highly integrated onboard.

The buttons are used4Key design: left button, right buttonOKKeys andCKey, among whichCReuse the key and power button.

It also has the functions of automatic recording, automatic storage, automatic calculation and automatic data processing, which greatly improves the efficiency of sampling detection, data calculation and processing, and report preparation, reduces the labor intensity of testers, and reflects the scientificity, progressiveness, fairness and accuracy of rebound detection.
