This document is the user manual for Fluke BT521 battery analyzer
The Fluke BT521 Battery Analyzer is a multifunctional meter designed for testing stationary battery systems. It measures internal resistance via Kelvin connections to determine system condition and deterioration. The device also measures DC voltage up to 1000 V, AC voltage up to 600 V, ripple voltage, and current using an auxiliary function or clamp.
| DC Voltage Measurement Range | up to 1000 V |
|---|---|
| AC Voltage Measurement Range | up to 600 V |
| Ripple Voltage Measurement | Yes |
| Safety Rating | CAT III 600 V |
| Internal Resistance Measurement Time | less than 3 seconds |
Each Fluke product is warranted to be free from defects in material and workmanship under normal use and service for three years.
An increase in internal resistance from a known baseline indicates that the battery is deteriorating.
The standard equipment includes BTL10 test leads, TL175 TwistGuard Test Leads, and an Interactive Test Probe set.
