Product Features

This AC battery internal resistance tester is a portable handheld testersthat measures main parameters specially designed for existing known batteries including lithium batteries , nickel-cadmium batteries, lead-acid batteries,alkaline batteries and other types of batteries.

• 1KHz AC low resistance measurement technology with noise filter technology . It can be used on thebatteries without disconnected from working condition
  

• Measuring principle 4-terminal Kelvin connection method to avoid interfere of wire resistance and contact resistance
  

• Auto range both in resistance and voltage measurement
  

• Simultaneously measure and display readings of battery resistance and voltage.
  

• Built-in ambient temperature measurement.
  

• Pass / Fail comparison function for resistance and voltage

1. -can be set to activate automatically and manually

2. -auto hold readings and comparison conclusion in one screen

3. -screen and buzzer indication of comparison conclusion

4. -store up to 30 groups of preset comparison parameters

5. -recall latest readings automatically when test resumes.
