3.2 Definition of Terms

A block is the smallest unit. A group of two or more blocks is
called a battery. For example, this can involve several blocks con­nected in series (e.g. a traction battery) or a group of batteries
consisting of two or more blocks in a UPS system.

Measurements can be conducted for individual blocks or batter­ies. From an organizational standpoint, a device under test is
always set up in the battery tester as a battery which includes one
or more blocks which will be measured. And thus if you only want
to measure one block, set up a battery with just one block.

5.8 RFID Reader

The display is surrounded by an RFID reader. If individual batteries
are equipped with an RFID tag (transponder), the tag can be
scanned before measurement, thus making it possible to subse­quently assign the measurement data to the respective DUT auto­matically 

125 kHz Technology

The RFID reader can only read RFID tags which use a frequency of
125 kHz. This technology offers several advantages:

• As one of the first RFID technologies, it’s widely used and easy

to obtain.

• It uses robust tags which are relatively insensitive to interfer-

ence from metals and liquids, which is crucial in battery envi-

ronments.

• Universal use (license-free ISM band)

• Minimal energy consumption (low-frequency long-wave band –

LF passive tags)

• Reading range: approx. 10 cm

• Small data transfer volumes with fast reading process (e.g.

only object ID as battery identification)

Reading RFID Tags

In order to read an RFID tag, hold the battery tester display 1 to
2 cm above the RFID tag. RF appears at display.

 32.

5.9 Attachment Options

The battery tester provides acoustic feedback for all important
procedural steps, e.g. readiness to record measured values. Con­sequently, there’s no need to continuously observe the display.

In order to ensure freedom of movement, comfort and quick work
for the operator, the battery tester can be secured by means of
various retaining devices for the entire duration of measurement:

• Carrying strap:

The operator can use the carrying strap to suspend the battery

tester around his neck. The condensed operating instructions



 include a description of how to attach the carrying strap.

• Retaining clip:

The operator can attach the battery tester to his belt with the

help of the retaining clip.

• Retaining magnet:

The battery tester can be attached to magnetic surfaces such

as battery cabinet doors with the retaining magnet.

8.3 Defining the Data(base) Storage Location

All data (measurement data, battery databases etc.) available in
BT PRO Manager are stored in a database.

Access is protected with the help of user accounts  19.
This database can be stored locally at a PC or remotely on a

server. The main difference between local and server-based data­bases is the number of user accounts: you can set up as many as
10 user accounts for a local database. Only one administrator can
be set up for a server database.

If necessary, you can create several databases and switch
amongst them. As a service provider, for example, you can create
separate databases for each customer.

A local database is created when BT PRO Manager is installed.
This is selected by default and can be used immediately.

8.6 Creating and Managing the Battery Database

Many battery systems are complex and their objects require inven­tory management. Inspecting the system involves all sorts of main­tenance and service work, for which measurements are required.
These measurements must be correctly assigned to the respective
object. This is the case regardless of whether you’re managing
your own system or customer systems as a service provider.

The location of the battery system, the battery itself, the number of
blocks in the battery and the limit values must be defined for mea­surements ( 18) performed with the battery tester (except MUL-
TIMETER). This makes it possible to evaluate the measurement in
an object-specific manner (type-dependent limit values etc.), and
assign it correctly to the object.

Manually entering the measurement parameters and manual trans­fer of the obtained measured values to your documents is of
course inconvenient, error-prone and very time-consuming.

In order to avoid this, a battery database can be created in
BT PRO Manager software. This makes it possible to visualize all
of your DUTs within a single digital structure. The battery database
must be kept up to date continuously, for example when replacing
units. The battery database is transferred to the battery tester after
it’s creative, and each time it’s changed.

Select the entry associated with the device under test from the
database on-site before starting the measurement. This assigns
the measured value to the respective object. After all measure­ments have been completed, transfer the results to BT PRO Man­ager for review and evaluation ( “Viewing Measurement Series
and Creating Measurement Evaluations (reports)”  25).

If you or your customers use an RFID system for asset manage­ment whose tags (transponders) operate at a frequency of
125 kHz, this can be taken advantage of. Instead of manually
selecting the entry for the DUT from the database, just scan the
RFID tag and the entry is selected automatically. The RFID tags
must first be linked (one time only) to the respective DUTs in the
database after creating the database to this end 

In order to be able to digitally map a system as an accurate repli­cation of the original, various entries are created and linked to
each other at different levels:

• The battery is the central unit (device under test).

•Block type (

battery.

• Block technology (

assigned in turn to each block type.

These 4 entries must be furnished with all relevant information, for
example the limit values required for the measurement.

Due to this linking, we recommend that you start at the lowest
level and work your way up.

8.8 Assigning RFID Tags to Batteries (DUTs)

Battery parameters, such as the battery identification number, are
required for measurements.

If you manage your system components with RFID technology,
you can take advantage of this during on-site measurement to
assign the performed measurement to a device under test.

Simply scan the RFID tag attached to the actual DUT with the bat­tery tester’s RFID reader during measurement ( 5). The corre­sponding digital DUT (battery) is automatically selected from the
battery database.

However, the RFID tags must first be linked to the database’s
respective DUTs after creating the battery database. The RFID tag
must be scanned and assigned to this end – direct manual entry to
the database in BT PRO Manager isn’t possible.

You can tell whether or not a DUT is already linked to an RFID tag
by looking at the bottom right-hand corner of the DUT’s entry:

– – – = no RFID tag assignment
– RF = RFID tag assigned

the RFID tag.
The battery tester reads the RFID tag. A brief acoustic signal
acknowledges recognition. The battery entry is displayed and
RF appears at the bottom right.

 The RFID tag is assigned to the battery. If you read the RFID

tag during a measurement, the measurement data are
assigned to the battery.

8.9 Importing Measurement Data

There are two ways to import measurement data to BT PRO Man­ager:

1. Connect the battery tester to the PC and read out the data.

9 Preparing Measurements

9.1 General Information (procedure)

Certain preparations must be completed before performing mea­surements:

1. Install BT PRO Manager software 

2. Create a battery database with BT PRO Manager 

You can manage all of your devices under test (batteries) in the
battery database, making it possible to select them during
measurement. The limit values required for the measurement
are defined in the database as well. If the specified limit values
are exceeded during a measurement, a brief acoustic signal is
generated and the measured value is displayed with a black
background.

If you’ve already completed this step, double check and
update your battery database.

Devices under test can also be defined at the instrument.
However, manually entered DUTs and their associated
measurement data cannot be transferred to the battery
database / BT PRO Manager. In order to transfer data, the
DUT must first be entered (a second time) to the software.
And thus devices under tests should only be entered man­ually in exceptional situations, for example if you encounter
unforeseen changes on site.

3. Transfer the battery database to the battery tester 

4. Optional: If you’re using an RFID system, assign the RFID tags

to the DUTs (batteries) via the battery database 

5. Switch polarity on or off  28.

If necessary, the polarity of the measured value doesn’t have
to be taken into account for the FLOAT, DISCHARGE, CHARGE and
CONNECTOR measurements. All measured values are then posi­tive (absolute values).

6. Inform yourself concerning use of the accessories 

The battery tester’s accessories are used for some measure­ments. Before beginning a measurement, familiarize yourself
with how to connect the accessories and use for intended pur­pose.

Kelvin Probes (Z227D) for 4-Wire Measurement

Electrical resistance is a dipole which can generally be measured
using two poles. A measuring current of predetermined magnitude
is directed through the device under test to this end and the resul­tant voltage drop is measured. The respective resistance value is
derived from the quotient of these two values. The two points
between which voltage is measured are decisive as regards the
results of the measurement. All resistances between these two
points (e.g. cable resistance) add to the measured resistance
value.

The included Kelvin probe can be used for measurement in order
to avoid this. In order to get the measuring device’s voltage mea­surement potential points as close as possible to the device under
test, the probe has separate connections for current supply and
voltage measurement. This type of 4-pole connection is known as
connection according to Kelvin.

10 Performing Measurements

Various measurements can be performed with the battery tester:

Measurement Description

MULTIMETER DC and AC voltage measurements without

storing measured values

FLOAT Periodic measurement of block voltages.

This measurement is used for quarterly re­cording of float voltage, for example in UPS
systems.

DISCHARGE Multiple measurement of block voltages at

short intervals during discharging (capacitance
test)

CHARGE Multiple measurement of block voltages at

short intervals during charging (capacitance
test)

RESISTANCE Periodic measurement of the internal resis-

tance of the blocks

TEMPERATURE Measurement of block temperature with an IR

temperature sensor

CONNECTOR Measurement of voltage drop to determine

connector loss between blocks

INTERVAL U Measurement of the voltage of a battery at any

desired time intervals (voltage curve)

INTERVAL U + I Measurement of the voltage and current of a

battery at any desired time intervals (voltage
and current curves)
Example: Recording of discharge current
during discharging.

DMA 35 (IrDA) Measurement of acid density and electrolyte

temperature within a block.
Measurements are performed with the
DMA 35 density meter from Anton Paar
GmbH.

DMA 35 (BT) Measurement of acid density and electrolyte

temperature within a block.
Measurements are performed with the
DMA 35 density meter from Anton Paar
GmbH.

The following subsections describe how measurements are per­formed. First read the general information which contains basic
information for all measurements (starting measurements, repeat­ing measurement etc.), and the information concerning on-site
selection of DUTs.

10.1 General Information

Starting Measurements

The following sections describe how specific measurements are
performed. Follow the specified steps and make sure that the
measuring points are properly contacted.

We recommend that you always contact the battery poles at the
same measuring points when performing repeat measurements so
that you obtain reproducible results.

On-Site Selection of the DUT to be Measured

In order to assign the measured values to a device under test (bat­tery), the DUT must be selected during measurement.

While preparing for measurement (
database with all DUTs and transferred it to the battery tester.

You can select the DUT from the battery database on site:

1. Via RFID (by scanning the RFID tag)

2. Via manual selection (using the keys on the battery tester)

If you encounter an unforeseen change on site, for example a new
battery about which you had not been informed, you can enter a
DUT manually.

Only create DUTs manually in exceptional cases.
Manually entered DUTs and their associated measurement
data cannot be transferred to the battery database /
BT PRO Manager. In order to transfer the data, the DUT
must first be entered (a second time) to the software 
““BT PRO Manager” PC Software”  18.

All 3 options are described in the following sections as part of the
measurement procedure.

Ending or Aborting Measurements

As a rule, measurements are performed over all specified blocks.
As soon as all measured values have been acquired, measure­ment is ended automatically.

A measurement can also be aborted. There are 2 way to do this:

1. Abort and save:
Press the OK key and acknowledge the security prompt with
OK.
The measurement is aborted and the measured values are
saved.

2. Abort without saving:
Press the FUNCTION key and acknowledge the security prompt
with OK.
The measured values are saved to the battery tester, but are
not transferred subsequently during data transfer.

 18), you created a battery

If you abort a measurement by mistake, respond to the security
prompt pressing the FUNCTION key. The display is returned to the
measurement view.

-------- appears at the display in order to indicate an incomplete or

faulty measurement. Furthermore, XXXXX appears in the measured
value display under the measurement’s designation instead of the
number of measured blocks.

An aborted measurement can be reactivated in order to finish it up
correctly (see following section).

10. Measure the measured value again.

 The measured value is saved.

Editing or Viewing Measurements

You can view and edit all measurements stored in the battery tes­ter directly at the instrument. This makes it possible to conduct ini­tial checking of the measurement results on site.

Normally, the measured values are displayed in black. However, if
a limit value is violated, the measured value is displayed with a
light-colored font and a black background for emphasis.

For a better overview, and for evaluation of the measurement
results, transfer the measurement data to BT PRO Manager soft­ware. Reports can also be generated with this program.

12.4 Fuse

A fuse is built into the device for protection.
The fuse is located in current-carrying conductor P+, which is con-

nected directly to the power transistor for resistance measure­ment. If the fuse blows, resistance measurement is no longer pos­sible.

The fuse is permanently installed. The fuse may not be re­placed by the user.

If the fuse blows, the battery tester must be sent to our repair ser­vice department or our respective foreign representative  53.

It can only be assured that type-tested fuses with the correct
blowing characteristics, current rating and breaking capacity are
installed if replacement is conducted by our repair service depart­ment or our respective foreign representative. At the same time,
technical safety inspection is also conducted on the instrument.

For service technicians:
Use only the specified type-tested fuse!
If fuses with other blowing characteristics, other current rat­ings or other breaking capacities are used, you and the
operator are placed in danger and protective diodes, resis­tors and other battery tester components may be dam­aged.
The use of repaired fuses or short-circuiting the fuse holder
is prohibited.

12.5 Accessories

No special maintenance is required for the accessories. Keep out­side surfaces clean.

Use a slightly dampened cloth to clean the multimeter measure­ment cable set (KS29), the alligator clips (KY95-3), the Kelvin
probes (Z227D), the rubber holster, the carrying strap and the car­rying case.

Avoid the use of cleansers, abrasives or solvents.

Never touch or clean the conductive ends of the test
probes!

Never clean the power pack.
