Overview

Adopting a high-performance 32-bit ARM microprocessor controlled micro handheld instrument, built-in large capacity lithium battery for ultra-long standby. The 3.5-inch true color LCD screen makes it easy for you to read measurement data. By measuring the voltage and internal resistance of the battery, the deterioration of the battery can be quickly judged. The instrument can test resistance from 0.1mΩ to 200.0Ω, DC voltage from 0 to 50V, with a maximum display of 3200 counts for resistance and 3000 counts for voltage. The resistance measurement of the instrument adopts the vector test principle, and the voltage measurement adopts the differential test principle, so the open circuit voltage can be accurately measured. In addition, the instrument has a professional sorting function and sorting buzzer setting, which can be applied to automatic sorting systems to complete fully automatic assembly line testing. The instrument can set data storage (up to 500 groups). It combines the portability of a handheld meter with the superior performance of a desktop instrument, and can be equipped with a USB interface for remote control and data acquisition and analysis, making it very suitable for assembly line inspection of various batteries and deterioration assessment of UPS batteries.
