Definition of Terms  
A cell is an electrochemical energy-storage device and represents the smallest technically usable unit. One or more cells in  
a housing form a block. In turn, a battery consists of a single block or a group of blocks which are connected in parallel  
and/or series. Sufficiently high voltages are generated by connecting units into a string. Together, one or more batteries  
and/or blocks, along with additional components (e.g. control systems, cooling, fuses etc.) form a system as the largest  
unit.  
A UPS system (uninterruptible power supply) usually consists of several rechargeable batteries, which in turn are made up  
of several blocks and electrical circuits (e.g. the charging equipment, control electronics for monitoring mains voltage and  
the inverter for converting outgoing direct voltage into alternating voltage).  
From an organizational standpoint, a device under test is always a battery where the battery tester is concerned. Informa-  
tion such as location (respective system) and the number of blocks is assigned to this battery.

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  
unit automatically 64.  
5.8.1 125 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 interference 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)  
5.8.2 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.

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 (31) performed with the battery tester (except MULTIMETER). This makes it possible to evalu-  
ate 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 created, 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  
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 or entered manually after creating the database to this end 49.  
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 (43) and location (44) are assigned to the battery.  
• Block technology (42) and manufacturer (43) are 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.

Note!  
Support blocks can be defined. Blocks of the same type and with the identical voltage (usually 2, 6 or 12 V) are con-  
nected in series in a UPS system in order to arrive at the voltage level required for the output load. If load output volt-  
age may not deviate from the specified load voltage, or may only deviate from it very slightly, so-called support blocks  
can be used. The voltage of these support blocks differs from standard voltages, and thus from the voltages of the  
blocks used in the system as well.  
No extra limit values can be specified for the support blocks. This function cannot be implemented in the METRA-

8.11 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 (12).  
The corresponding digital DUT (battery) is automatically selected from the battery database.  
In order to ensure that this works, you can enter the RFID manually to BT PRO Manager when creating the battery data-  
base, or link the RFID tags to the respectively associated database DUT after creating the battery database. The RFID tag  
must be scanned and assigned to this end.  
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  
You’ve created a battery database which includes all devices under test "Creating and Managing the Battery Data-

An acoustic signal indicates that the RFID reader is ready. – – – – – > () < – – – – – appears at the display.  
9. Hold the battery tester with its display roughly 1 to 2 cm above 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.

Preparing Measurements  
9.1  
General Information (Procedure)  
Certain preparations must be completed before performing measurements:  
1. Install BT PRO Manager software 31.  
2. Create a battery database with BT PRO Manager 31.  
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 dis-  
played with a black background.  
If you’ve already completed this step, double check and update your battery database.  
Note!  
Devices under test can also be defined at the instrument. However, manually entered DUTs and their associated mea-  
surement 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 47.  
4. Optional: If you’re using an RFID system, assign the RFID tags to the DUTs (batteries) via the battery database 49.  
5. Switch polarity on or off 59.  
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 60.  
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.  
The various measurements can now be performed 62.  
9.2  
Switching Polarity On or Off  
When this function is switched on, the polarity of the measured value is taken into account for the float, discharge and charge  
measurements.  
If the function is switched off, the polarity of the measured value isn’t taken into account for the float, discharge and charge  
measurements. In this case, all measured values are positive (absolute values).  
1. Switch the battery tester on 16.  
2. Press the OK key.  
The main menu appears.  
3. Select SETTINGS from the main menu using the ▼ ▲ keys.  
The SETTINGS menu is displayed.  
4. Press the OK key.

9.3.3 Kelvin Probes (Z227D) and Angled Kelvin Probes (Z227W) for 4-Pole 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.  
In order to avoid this, the included Kelvin probes (Z227D), or the optionally available angled Kelvin probes (Z227W 9) for  
more difficult to access measuring points, are used for measurement. In order to get the measuring instrument’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.

Measurements are performed with the DMA 35 density meter (version 4) 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 concern-  
ing on-site selection of DUTs.  
10.1 General Information  
10.1.1 Starting a Measurement  
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 measure-  
ments so that you obtain reproducible results.  
10.1.2 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 (31), you created a battery 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.  
Note!  
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  
All 3 options are described in the following sections as part of the measurement procedure.

measured. The measurement is performed regularly at certain intervals, e.g. as a quarterly inspection of a UPS system.  
Note!  
Polarity can be switched off 59. If polarity is switched off, the absolute value of the measured value is recorded.  
Note!  
Perform the FLOAT measurement before conducting temperature or acid density measurements.

10.6 Resistance Measurement  
Voltages and internal resistances are measured for the blocks of a given battery with the RESISTANCE measuring function.  
As a special feature of the internal resistance measurement, “electrical resistance R ” and “charge transfer resistance R ”  
el  
ct  
are measured simultaneously. R (direct current resistance) is arrived at by combining these two resistances:  
DC  
• “Electrical resistance R ” represents strictly electrical losses. These losses occur at, for example, plate straps, plate grids and  
el  
electrolytes. The battery delivers rapidly changing currents via this resistance, for example for switched-mode DC/DC convert-  
ers.  
• “Charge transfer resistance R ” is used to characterize the ability of a block to accumulate and release a charge. This makes  
ct  
it possible to identify battery blocks which are operating at a loss with regard to float.  
A 4-wire measurement is performed in order to compensate for cable resistance. Use the included Kelvin probes (acces-  
sory Z227D) to this end, or for less readily accessible measuring points, the optionally available angled Kelvin probes  
Attention!  
Caution: Sparking  
!
During the resistance measurement, test current flows which may result in sparking.  
Resistance measurement  
– May only be performed at voltages of less than 24 V.  
– May only be performed where hydrogen concentrations in the air comply with DIN EN 50272-2  
– Must not be performed immediately after the battery system has been charged – wait for at least 30 minutes  
– May only be performed in well-ventilated battery rooms  
The Kelvin probes (Z227D) or the angled Kelvin probes (Z227W) are available.  
Polarity is switched on.

it.  
Deactivated measurements remain in memory at the battery tester, but aren’t transferred during data transmission and are  
thus excluded from evaluation.  
1. Switch the battery tester on 16.  
2. Press the OK key.  
The main menu appears.  
3. Select DATA MENU from the main menu using the ▼ ▲ keys.  
The DATA menu is displayed.  
4. Select SHOW DATA using the ▼ ▲ keys.

6. Press and hold the FUNCTION key until you hear a brief acoustic signal.  
The number of blocks changes to “XXXXX.  
The measurement is deactivated.  
11.4 Deleting Measured Values  
Measurement data stored at the battery tester must be transferred to an external PC for data evaluation and storage.  
After successful transmission, the measurement data in the battery tester can be deleted so that sufficient memory space is  
once again available for future measurements.  
Note!  
All measurement data are deleted. Individual measurements cannot be deleted separately.  
1. Switch the battery tester on 16.  
2. Press the OK key.  
The main menu appears.

7. Press the OK key.  
Note!  
Press the FUNCTION key if you want to abort deletion.  
All measured values stored at the battery tester are irretrievably deleted.  
11.5 Saving Measured Values to a PC (Data Backup)  
We recommend backing up measurement data to a PC or other external storage medium at regular intervals. Any possible  
loss of data can be prevented in this way.  
When measurement data is transferred to BT PRO Manager software, an additional CSV file which contains the measure-  
ment data is automatically saved to the PC "Importing Measurement Data" 50.  
If you’re not using BT PRO Manager, you can transfer the measurement data as a CSV file from the battery tester to a PC  
for backup via a wireless interface connection.  
In either case, the file is saved to the PC and can be transferred to another medium or edited with a text editor.  
Attention!  
!
The file may be damaged during editing.  
– Before editing, save an additional backup copy.  
– Edit the CSV file with a text editor only.  
®
®
Microsoft Excel and other programs may destroy the file.
