Applications

Intended Use / Use for Intended Purpose
Periodic testing and well-organized maintenance are necessary in order to assure the availability of stationary battery systems. The METRACELL BT PRO is a multifunctional instrument for testing batteries and battery blocks* (referred to below as “devices under test” or “DUTs”). It can be used to determine the current status of a DUT, and to pinpoint concealed defects. The battery tester is used primarily for testing DUTs in stationary battery systems.

The instrument stores the measured values internally. All recorded measured values can be viewed on site. Each value can be conveniently re-measured if necessary. Management of devices under test, as well as evaluation and backup of the measured values, is handled by the included “BT PRO Manager” software. The measured values can also be transferred to an external computer as a CSV file.

The battery tester is a portable instrument which can be held in the hand while performing measurements.

Safety of the operator, as well as that of the instrument, is only assured when it’s used for its intended purpose.

Attention!
Read and adhere to the operating instructions. Full operating instructions can be found at http://www.gossenmetrawatt.com.

Use for Other than Intended Purpose
Using the instrument for any purposes other than those described in these condensed operating instructions, or in the instrument’s operating instructions, is contrary to use for intended purpose

Liability and Guarantee
Gossen Metrawatt GmbH assumes no liability for property damage, personal injury or consequential damage resulting from improper or incorrect use of the product, in particular due to failure to observe the product documentation. Furthermore, all guarantee claims are rendered null and void in such cases.

Nor does Gossen Metrawatt GmbH assume any liability for data loss.

Opening the Instrument / Repairs
The instrument may only be opened by authorized, trained personnel in order to ensure flawless, safe operation and to assure that the guarantee isn’t rendered null and void. Even original replacement parts may only be installed by authorized, trained personnel.

Unauthorized modifications to the instrument are prohibited.

A block is the smallest unit. A group of two or more blocks is called a battery. 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.

If it can be ascertained that the battery tester has been opened by unauthorized personnel, no guarantee claims can be honored by the manufacturer with regard to personal safety, measuring accuracy, compliance with applicable safety measures or any consequential damages.

Measuring Inputs

All measuring inputs refer to ground and reference potential, P/COM input. The measuring inputs are not electrically isolated from each other. The measuring ranges depend on the respective measuring inputs

Resolution: 0.01 mV Input impedance: > 10 MWSensing lead to minus pole during resistance measurement.
P−/COM| Reference potential (ground potential) of all measuring inputs.Current conducting cable to minus pole during resistance measurement.
S+| Measuring input for direct and alternating voltage measurements. Measuring ranges:  ±24.5000 VDC   Resolution: 0.1 mV±600.000 VDC     Resolution: 1 mV0…300.00 VAC Resolution: 10 mV Input impedance: 1.6 MWSensing lead to plus pole during resistance measurement.
P+| Current conducting cable to plus pole during resistance measurement. !

Attention!Max. 24 V DCMaximum test voltage must not exceed 24 VDC at input P+.  The instrument is damaged if this value is exceeded.

Note!
600 V CAT III refers to measuring inputs S+, S− and P−/COM.

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

The RFID reader can only read RFID tags which use a frequency of 125 kHz. In order to read an RFID tag, hold the battery tester display 1 to 2 cm above the RFID tag. RF appears at display

Electrical Power Supply
The battery tester is operated with rechargeable NiMH batteries. Please observe the following for battery replacement:

Attention! !

Risk of injury due to contact with dangerous voltages. Only use the instrument when the battery compartment cover is inserted and firmly screwed into place.

R equired tool s: Philips screwdriver

• The battery tester must be switched off.
•  All measurement cables and accessories must be removed from the instrument.

1. Remove the holster from the instrument: Press against the bottom of the holster at the front and push it back and off of the instrument. As soon as the lower part of the instrument is exposed, pull the instrument completely out of the holster.

2. Place the instrument face down on a stable surface.

3. Loosen and remove the screw from the battery compartment cover.

4. Unlock and remove the battery compartment cover.

5. Insert the 4 rechargeable batteries into the battery compartment, making sure that the plus and minus poles match up with the provided polarity symbols.
   Attention! !
   Only the included batteries or those specified in the technical data (8) may be inserted and used.

6. Place the battery compartment cover onto the battery compartment and press it until it audibly clicks into place.

7. Secure the battery compartment cover with the screw.

8. Pull the holster back over the instrument: Observe the cut-outs in the holster for the front panel and the connections. Push the instrument into the holster at the top first as far as it will go. Then press on the front at the bottom until the instrument is fully reinserted into the holster

The batteries have now been inserted. The instrument can be used. Operating time is approximately 10 hours when the batteries are fully charged. A warning is generated when battery voltage drops to below 4.8 V. The battery tester can be operated for approximately one more hour after this warning is generated.

Attach the Carrying Strap (optional)
The battery tester gives an acoustic feedback after any important operation, such as, for example, readiness for the acquisition of measured values. Thus there is no need for you to observe the display permanently.

In order to ensure freedom of movement, convenience and faster working 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.
• Retaining clip: The operator can attach the battery tester to his belt with the help of the retaining clip.
• Retaining magne t: The battery tester can be attached to magnetic surfaces such as battery cabinet doors with the retaining magnet.

The carrying strap is shipped loose and must first be inserted:

1. Pull one end of the strap out of the locking clasp. The locking clasp remains on the strap.
2. Feed the end of the strap through the eyelets on the instrument: Push the strap into one of the eyelets at the bottom of the instrument until it comes out at the side of the instrument. The top side of the retaining clasp faces out.
3. Thread the end of the strap from above through the locking clasp on the strap.
4. Repeat steps 1 through 3 with the other end of the strap on the other side of the instrument.
5. Adjust the length of the carrying strap by pulling on its ends.

• The carrying strap has now been attached.
