It allows for accurate voltage and current measurement, as well as load testing, making it an indispensable tool

for assessing the quality and safety of USB ports

The Uni-T UT658 tester offers voltage measurements in the range from 3 V to 9 V with an accuracy of ±1% and a resolution of 0.01 V.

It also allows for precise current measurement from 0 A to 3 A with an accuracy of ±(1%±2) and a resolution of 0.01 A.

The function of testing the charge transferred to a USB device (up to 9999 mAh) allows you to monitor and evaluate the battery condition and charging efficiency.

The tester has memory that can store up to 10 measurements, allowing for quick comparison of results and subsequent data analysis.

This is particularly useful when monitoring multiple devices or USB ports.
