Internal AC Resistance Tester for All Batteries (AC@1KHZ, 1 - 3999 m-ohm) - EQ-MSK-BK300

• Adopts sine wave AC power with a frequency of 1000Hz to carry out the test on the battery's internal resistance. AC current used for the test is about 10mA.
• Applicable for internal resistance test of conventional capacitance single battery and its battery group. 
• Built-in standard precision resistance (50 m-ohm), facilitating the user to calibrate the instrument test accuracy.
• Capable of judging synchronously battery internal resistance and voltage, using the microprocessor to set the upper/lower limit of the internal resistance and voltage alarm, outputting the audible and visual alarm.

Available battery voltage measuring range

• Two selectable ranges:
• DC 0 ~ 4.999V +/- (Accuracy: 2mV + 0.5% FS  with resolution +/- 1mV)
• DC 5 ~ 19.99V +/- (Accuracy: 20mV + 0.5% FS  with resolution +/- 10mV)

Battery internal resistance

• Two selectable ranges:
• 1m-ohm ~299.9m-ohm:    Accuracy:   +/- (0.5% FS + 0.5 m-ohm) with resolution  +/- 0.1m-ohm
• 300 m-ohm ~3999m-ohm:  Accuracy +/- (0.5% FS +5 m-ohm) with resolution +/- 1.0 m-ohm
