Comes equipped with the BTL20 test probe, this battery analyzer is designed to take measurements on stationary batteries of all types. Additionally, this tool covers a broad range of battery test functions ranging from DC voltage and resistance tests to full condition testing.

Fluke BT520ANG Offers

Reduced testing complexity, a simplified workflow and an intuitive user interface provide a new level of ease-of-use in battery testing.

Ideal test tool for maintenance, troubleshooting, and performance testing of individual stationary batteries and battery banks used in critical battery backup applications. The intuitive user interface, compact design, and rugged construction ensure optimum performance, test results, and reliability. The battery analyzer covers a broad range of battery test functions ranging from DC voltage and resistance tests to full condition testing using an automated string function testing and the test probe integrated infra-red temperature measurement system.

Voltage and resistance thresholds

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.

Fluke 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.
