Profitec BT 105 A User manual

Operating instructions for BT 105 A
Please read carefully and keep in a safe place before putting into operation!
Functional description
With this battery tester you can check the capacity/voltage of the most common types of batteries
(button cells, Mignon, Baby, Mono, 9-volt batteries and photo batteries) such as standard inc-carbon
batteries, alkaline, mercury, silver oxide and lithium batteries. Depending on the switch position, the
battery to be tested is loaded by a resistance corresponding to the operating data. The measurement
result can be read on a clear pointer instrument.
Suitable for the following batteries and rechargeable batteries
All 1.5 V round cells (AAA, AA, C, D, N)
4,5 / 6 / 9 / 12 and 22,5 Volt Batteries
1.5 Volt button cells up to 20 mm diameter
1,5 / 3 and 6 V Photo batteries
3 V Lithium cells
Intended use
The BT 105 A battery tester is used to check/test batteries up to a nominal voltage of 22.5 volts. Other
batteries, as mentioned in these operating instructions, cannot be tested with this device.
Operation under the following adverse conditions is not permitted:
Wetness or excessive humidity
Dust and flammable gases, vapours or solvents
Thunderstorms or thunderstorm conditions such as strong electrostatic fields, etc.
Any use other than that described above will damage the battery tester and is also associated with
ha ards such as short-circuits, fire, electric shock, etc. The device must not be modified or converted!
The safety instructions must be observed!
Important safety and ha ard information
This is not a toy for children. Therefore, keep the battery tester away from children and store it
in a childproof place.
When used in commercial facilities, the accident prevention regulations of the Federation of
Institutions for Statutory Accident Insurance and Prevention for electrical systems and
equipment must be observed.
Never switch on the appliance immediately when it is brought from a cold to a warm room.
Under unfavourable circumstances, the resulting condensation can destroy your appliance.
Allow the unit to come to room temperature when it is switched off.
Avoid strong magnetic fields, such as those found near machines or loudspeakers.
Repairs may only be carried out by authorised specialist personnel. Before opening the unit, it
must be disconnected from all voltage sources.
The meter is only suitable for checking batteries/rechargeable batteries; under no
circumstances should it be used to measure DC voltages above 24 V.
Never measure alternating voltages (>25V) with the unit, there is a danger to life!
It is essential that the range switch is set to the correct range before each measurement,
otherwise the unit may be damaged by overloading.
Before each test, be sure to observe the polarity of the battery to be tested.
The measuring tips must be removed from the object to be measured before each change of
the measuring range.
The unit is not suitable for testing lead-acid or lead-gel batteries.

The unit must not be used in electric circuits.
Before each measurement, check the meter and the test leads for damage.
Do not expose the unit to high temperatures, strong vibrations or high humidity.
If it can be assumed that safe operation is no longer possible, the unit must be taken out of operation
immediately and secured against unintentional operation. Safe operation can no longer be assumed if
the unit no longer functions, shows visible damage, has been damaged during transport or has been
stored under unfavourable conditions.
This unit has left the factory in perfect condition with regard to safety. In order to maintain this
condition and to ensure safe operation, the user must observe all safety and ha ard information
contained in these operating instructions.
This unit is CE-approved and therefore meets the necessary European and national requirements for
electromagnetic compatibility.
In the event of damage caused by non-observance of these operating instructions, the
warranty claim becomes void! We accept no liability for consequential damage or damage to
property or personal injury caused by improper handling or failure to observe the safety
instructions!
This meter is not suitable for testing car/motorcycle/boat batteries. Nor can it be used to
determine the state of charge of rechargeable NiCd/NiMh batteries.

Measurement
Select the desired battery type with the range switch. Then select the test connection suitable for your
battery type (see picture).
All types Test leads (red = plus, black = minus).
Hold the test probes to the contacts of the battery.
Round cells Red test probe and minus measuring point on the unit.
Hold the minus contact on the measuring point of the BT 105 A and the red test probe
on the plus contact of the battery.
9 Volt block 9 test points on the BT 105 A.
Place the battery contacts so that the contacts match the test contacts on the battery
tester.
Button cells Test compartment on the right side.
Place the button cells in the side compartment of the battery tester with the negative
pole facing upwards. Then press the grey button all the way down.
Observe the correct polarity "+" and "-" for all measurements ! If the polarity is incorrect, the
pointer of the instrument will deflect to the left, which can damage or destroy the sensitive
measuring mechanism.
Keep the measurement times as short as possible, as the batteries/rechargeable batteries are
stressed by the measurement. A longer measurement reduces the capacity of the batteries.

Evaluation of the display
Display Capacity
„GOOD“ green Adequate to good
„REPLACE“ red Very weak to none
The upper scale applies to all normal batteries and the middle scale to all button and lithium cells. The
lower scale is intended for rechargeable batteries. However, no reliable statement about the capacity
of rechargeable batteries can be made with this device.
Zero adjustment
If the movement is out of adjustment, e.g. after a long period of non-use or after a fall, the unit should
be readjusted. To do this, proceed as follows:
1. Insert a suitable flat-blade screwdriver into the adjustment screw.
2. Turn the screw slowly until the pointer is exactly above the point on the left side of the scale.
Note: Do not test batteries during this setting!
Maintenance and disposal
Except for occasional cleaning, the battery tester is maintenance-free. To clean the
device, use a clean, lint-free, antistatic and dry cleaning cloth. Do not use any abrasive,
chemical or solvent-based cleaning agents. Dispose of the device that has become
unusable in accordance with the applicable legal regulations.
