DESCRIPTION This instrument makes use of the characteristics that the battery is equivalent to active resistance, and gives the tested battery a constant ac current of 1000HZ and about 10mA, and then carry out a series of processing such as voltage sampling, rectification, and filtering, so as to accurately measure the internal resistance of the battery. The measurement error caused by contact resistance is effectively eliminated and the measurement accuracy is improved by using the fixed zero methods. SPECIFICATION Supply Voltage: DC9V Power voltage adapter(or 9V Battery) Display Voltage: DC 0~26.00V Display resolution 0.01V Display Resistance: 1.00 mΩ~3000.00 mΩ; Display resolution: 1mΩ AC Current Frequency: 1KHZ Maximum Power: ≤1W Outer Size: 84 ×152 ×32mm(Width×Length×Height) Off Time: It will shut down automatically in about 3 minutes after the test stopped. WHAT'S IN THE PACKAGE 1 x Battery Resistance Tester 1 x Four Wire Test Clip 1 x Four Wire Test Pen
