Key features

Fluke BT510 key features:

  • Battery Voltage – During the internal resistance test, Fluke Battery Analyzers also measure the voltage of the battery under test
  • Discharge Volts – The Discharge mode collects the voltage of each battery multiple times at a user defined interval during a discharge or load test. Users can calculate the time a battery takes to drop to the cut-off voltage and use this time to determine the capacity loss of the battery
  • Ripple Voltage Test – Measures unwanted residual ac component of the rectified voltage in dc charging and inverter circuits. Allows users to test ac components in dc charging circuits and find one of the root causes of battery deterioration
  • Meter and Sequence Modes – The Meter mode is used for a quick test or troubleshooting. In this mode you can save and read the readings in a measurement or time sequence. The Sequence mode is for maintenance tasks with multiple power systems and battery strings. Before a task starts, users can configure a profile for the task for data management and report generation
  • Threshold and Warning – Users can configure a maximum of 10 sets of thresholds and receive a Pass/ Warning/ Fail indication after each measurement
  • Intercell Strap Resistance Test and Data Management – Measures the resistance of the intercell connection between batteries in a string. Once the measurements are completed Fluke Battery Management Software version 1.0.69 can now report the strap resistance for a battery string or historical data over time.
  • AutoHold – When AutoHold is turned on, a reading is captured when it remains stable for 1 second. The reading is then released when a new measurement starts
  • AutoSave – When AutoSave is turned on, measured values are saved to internal memory automatically after an AutoHold reading is captured
  • Fluke Battery Management Software – Easily import data from the Product to a PC. The measurement data and battery profile information is stored and archived with the Management Software and can be used for comparison and trend analysis. All measurement data, battery profile and analysis information can be used to easily generate reports
  • Comprehensive logging – All measured values are automatically captured during testing and can be reviewed on the instrument before downloading for on the-go analysis
  • Optimized user interface – Quick, guided setup ensures you're capturing the right data every time
  • Battery life – 7.4 V 3000 mAh lithium-ion battery for more than eight hours continuous operation.
  • USB port – For fast data download to supplied data analysis and report management application software.
  • Highest safety rating in the industry – CAT III 600 V, 1000 V dc max. rated for safe measurements all around the battery power supply equipment.

Voltage and Resistance Thresholds

Fluke Battery Analyzers allow 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 and threshold indications are determined based on the following criterion:

Voltage Resistance
> Voltage Lower < Voltage Lower < Reference > Reference and Reference x (1+Warning %) > Reference x (1+Fail)
Pass Fail Pass Warning Fail

Fluke Battery Management Software

Fluke Battery Management Software Easily 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 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

Rated 4 out of 5 by from BT521 don't have temp display on the unit itself The BT521 could measure the negative pole temperature but could not be displayed on the unit itself. The only way to review the temp data is to download the data to the PC. This temp data should be able to review on the unit itself during the site testing. All current test probes are straight only. If Fluke could provide the angled tip, it would be best for tight environment since the workable space on top of the battery bank are quite limited in most of the environment. All accessories are not upgradable, i.e. BT510 could not be upgraded to BT520, and BT520 could not be upgraded to BT521. However the time of purchasing this sort of instrument may not have adequate budget to purchase the top of the series model. If it is upgradable, it will be fine for the starter since most of the accessories could be an optional item. I'm not sure whether this BT5xx will be compatible with the Fluke Connect in the future. The BT521 is already equipped with Bluetooth connectivity to iOS devices. I hope it will be supported by Fluke Connect in coming soon such that my Fluke Connect ready equipment could be managed together under a single platform.
