JK625/JK625L Battery Internal Resistance Tester
JK625/JK625L Battery Internal Resistance Tester is an on-line instrument for measuring battery internal resistance and voltage. It is controlled by a high performance 32-bit ARM microprocessor.Fully automatic real-time detection of miniature hand-held instruments, built-in large capacity lithium batteries to achieve ultra-long standby.JK625/JK625L combines the advantages of portable hand-held watch and desktop instrument. Its main performance is compatible with daily set 3554.The instrument can test resistance of 0.1mΩ~3.3000Ω/ 0.001mΩ~3.3000Ω , DC voltage of 0.001~60.000V/0.0001~60.000V, data display is stable, resistance is up to 3300 display bits, voltage is up to 6000 display bits.
The resistance measurement of the instrument is based on the principle of vector measurement and the voltage measurement is based on the principle of differential measurement, so the open circuit voltage can be measured accurately.In addition, the instrument has professional sorting function, built-in sorting records, GD/NG sorting results show sorting signal settings, which is applied to UPS online battery measurement automatic sorting system to complete automatic pipeline testing.JK625/JK625L is equipped with 500 sets of data storage, which can save measurement data by one key and save you the time of recording data.It can also be equipped with USB interface for remote control and data acquisition and analysis, which makes it very suitable for pipeline inspection of all kinds of batteries.
