Product Overview

The Fluke BT521 Battery Analyzer (the Product) is a multifunctional meter designed for

the test and measurement of a stationary battery system. The Product can measure the

battery internal resistance (hereinafter referred to as “resistance”) and voltages. These

measurements can be used to determine the overall condition of the system. It can also

measure electrical parameters for battery system maintenance, including dc voltage up

to 1000 V, ac voltage up to 600 V, and ripple voltage.

Features of the Product include:

• Threshold and Warning – Users can configure a maximum of 10 sets of thresholds

and receive a Pass/Fail/Warning indication after each measurement.

• Meter and Sequence Modes – The Meter mode is for a quick test or trouble-

shooting. In this mode you can save and read the readings in a time sequence. The

Sequence mode is for maintenance tasks with multiple power systems and battery

BT521

strings. Before a task starts, users can configure a profile for the task for data

management and report generation.

• Discharge Volts – The Discharge mode collects the voltage of each battery several

times at a certain 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 this battery.

• AutoHold – When AutoHold is turned on, the Product freezes the reading when it

remains stable for 1 second. The frozen reading is released when a new

measurement starts.

• AutoSave – When the AutoSave mode is on, measured values are saved to the

internal memory of the Product automatically after AutoHold.

• CAT III 600 V Safety Rated – The product can measure a maximum of 600 V ac in a

Category III environment.

• Ripple Voltage Test – Measures the 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.

• Fluke Battery Analyze Software – Easily import data from the Product to a PC. The

measurement data and battery profile information is stored and archived with the

Analyze 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.

Introduction

This chapter provides information about how to use the Product. The Product provides

two modes for different measurement purposes: Meter mode and Sequence mode.

Meter mode lets you perform easy and fast measurements and save the measurement

readings and timestamp to the Product memory. In this mode, the Product measures

battery resistance and voltage, dc voltage, ac voltage, and ripple voltage.

Sequence mode is designed for professional battery maintenance personnel who work

between multiple test sites. In this mode, you can create a profile for each battery string

to be tested. The profile specifies information such as user-defined test site, device type,

serial number, battery quantity, and battery model. During the test, all test data, including

battery resistance, voltage, and ripple voltage is stored in the profile. After a battery

string test is completed, you can create a new profile for the next battery string or test

site. You can also recall or delete the test data in a history profile.

With the integrated profile management and the analysis software on the PC, you can

analyze the trend of maintenance data and create reports in an efficient way. For

example, you can create a comprehensive test and maintenance report for a test site or

analyze the resistance changes of one battery string over time.

2. Use  to set No. to ---.

3. Push the Confirm softkey.

The T-X icon no longer shows on the display.

How the Thresholds Work

When a threshold set is applied, the Product compares each resistance reading with the

resistance reference in the current threshold set.

• If the reading is greater than reference x (1+Fail threshold), the Product shows FAIL

on the screen, indicating that the tested battery is potentially compromised and

should be further investigated.

• If the reading is greater than Reference x (1 + Warning threshold) but less than

Reference x (1 + Fail threshold), the Product shows WARN on the screen, indicating

that the tested battery requires further attention and increase in test frequency.

• If the reading is less than Reference (1+ Warning threshold), the Product shows

PASS on the screen, indicating that the tested battery is within the defined tolerance

limits.

For example, you have applied a threshold set where Resistance Reference is set to

3.00 mΩ, Warning set to 20 %, and Fail set to 50 %. The Product shows FAIL for

resistance readings greater than 3.00 x (1 + 50 %) = 4.50 mΩ. It shows PASS for

resistance readings less than 3.00 x (1 + 20 %) = 3.60 mΩ. It shows WARN for

resistance readings less than 4.50 mΩ but greater than 3.60 mΩ.

At the same time, the Product compares each stable voltage reading with the lower

voltage from the applied threshold set. If the reading is less than the lower voltage

threshold, the product shows FAIL on the display. If the reading is greater than the

threshold, the product shows PASS on the display.

Note

If the resistance test and the voltage test have different results, the

Product shows the worse result. For example, the resistance

indicates PASS but the voltage indicates FAIL, the Product still

shows FAIL on the display.

Clean the Product with a damp cloth and a mild soap. Do not use abrasives, solvents, or

alcohol. These may damage the Product markings and labels.

Charge the Battery

When the Product is powered by the battery, the battery charge symbol in the screen

header informs you about the charge condition. This symbol ranges from fully charged to

empty.

The % increments are:

• Empty: 5 % - 20 %

• 1 cell: 20 % - 50 %

• 2 cells: 50 % - 70 %

• 3 cells: 70 % - 100 %

To keep the battery in optimal condition, it must discharge fully and then charge it. A full

charge takes approximately 3 hours with the Product turned off. Repeat this at least

twice a year.

Figure 7-3 shows how to charge the battery.
