Device name: battery internal resistance tester
Model: BK - 300A
Main performance and technical parameters:
Equipment performance
Test type ac internal resistance test
Test method: four-wire measurement
Ac current frequency 1KHZ±0.1KHZ
The voltage is measured in two levels
Dc 0 ~ 5.000v, resolution 1 mV, accuracy ±(0.2% RDG +5dgt).
Dc 5.00v ~ 20.00v, resolution 10mV, accuracy ±(0.2% RDG +5dgt)
There are two levels of internal resistance measurement
Low range: 3 m Ω ~ 300.0 m Ω test current 10 ma, + 0.3% RDG + 5 DGT.
Ω high range: 300 m ~ 3000 m Ω test current 1 ma plus or minus 0.3% RDG + 5 DGT.
Internal resistance calibration potentiometer calibration (standard resistance box shall be purchased separately)
The test alarm can be set with unqualified internal resistance alarm or qualified alarm
Fixture type air plug, can connect fixture box or test line
