Voltage and resistance thresholds

Allows you to quickly and easily define upper and lower measurement thresholds or tolerance ranges. During the testing process, measured values are automatically compared to the predefined threshold levels producing a PASS, FAIL or WARN indication after each measurement. A maximum of 10 sets of thresholds can be stored.

Battery Management software

The Battery Management Software allows you to quickly and easily import data from the battery analyzer to a PC. The measurement data and battery profile information is stored and archived with the Management Software and can be used compare results, switch results between conductance and resistance (requires Software Management software version 1.0.69 or later) readings and perform trend analysis. All measurement data, battery profile and analysis information can be used to easily generate reports.

  • Quick view saved readings
  • Profile management
  • Histogram of a battery string with end user defined threshold
  • Historical trend data of batteries
  • Multiple rounds of discharge voltage
  • Quick Report Generation
  • Upgrade Fluke Battery Analyzer firmware
  • Switch measurement results between conductance and resistance readings

Battery Analyze mobile app

Offers wireless communication for data download and remote display while measuring via the dedicated Battery Analyzer mobile app. Using the Battery Analyze mobile app you can:
