Starter test
Attention! During the starter tests, the load switch must not be turned on. Before the starter tests, it is required to conduct a test
of the accumulator under load and write down the voltage value. Attention! Is the test of an accumulator under load did not indi-
cate a full capacity of the accumulator, the starter test will not succeed.
The engine of the vehicle should reach its normal working temperature, and then it should be turned off. Connect the tester as in
the case of testing of an accumulator. Start the engine and observing the indicator write down the voltage value.
Compare the voltage values from the test under load and the starter test, using the following table.
If the observed value is lower than the one indicated in the table, the cranking current is too high. Is may be a result of bad con-
di- tions of the contacts, a damaged starter or engine, or an insufficient capacity of the accumulator.
MAINTENANCE OF THE DEVICE
The device does not require any special maintenance. A dirty housing should be cleaned with a soft cloth or with a compressed
air jet, whose pressure must not exceed 0.3 MPa.
Check the conditions of the terminals of the conductors before and after each use. Remove any signs of corrosion, which might
disturb the flow of the electric current. Avoid contamination of the terminals with the electrolyte from the accumulator, since it
would accelerate the process of corrosion.
The device should be stored in a dry place, away from unauthorised persons, particularly children. Make sure the cables and
conductors are not damaged during storage.

Press and release the load switch, which will cause a 100
A current to flow through the load for 10 sec.
If when the load is on the green „OK” diode is lit, the accu-
mulator is loaded to its full capacity. Write down the dis-
played voltage value.
If the yellow „WEAK” diode is lit, but the voltage value shown
by the indicator is constant, the accumulator is not loaded to
its full capacity. It is then required to check the capacity of the
accumulator using other methods, e.g. checking the density
of the electrolyte with an aerometer.
If the red „BAD” diode is lit and the voltage value is decreas-
ing, it may be necessary to replace the accumulator with a
new one.
Tests of the charging of the accumulator
ATTENTION! When the engine is operating, the load switch
must not be turned on. Connect tester as in the case of
testing of an accumulator.
Start the engine and wait until it has reached the normal wor-
king temperature. Maintain the rotation of the engine within
the range of 1200 – 1500 rpm.
The indicator should show a value within the range of 13.5 -
15 V. If other values are indicated, the accumulator is not loa-
ded to its full capacity. It is then required to check the capacity
of the accumulator using other methods, e.g. checking the
density of the electrolyte with an aerometer.
model 07 173, analogue
Observe the arrow while the load is on. If the arrow is in
the green area, the accumulator is loaded to its full capaci-
ty. in case of the most popular 12 V accumulators the
green area of the scale is arranged in steps, depending on
the cold cranking current of the accumulator (200 - 1000
A). The parameter of the cold cranking current (CCA) is
specified in the documentation of the accumulator.
If the arrow is outside the green area, but it does not drop
towards the lowest value of the scale, the accumulator is not
loaded to its full capacity. It is then required to check the capa-
city of the accumulator using other methods, e.g. checking
the density of the electrolyte with an aerometer.
Testing of the charging of the accumulator
ATTENTION! When the engine is operating, the load switch
must not be turned on. Connect the tester as in the case of
testing of an accumulator.
Start the engine and wait until it has reached the normal wor-
king temperature. Maintain the rotation of the engine within
the range of 1200 – 1500 rpm.
Check the indication; if the arrow is within the green area, the
charging system is working properly.
The arrow in the red area means an incorrect operation of the
charging system. It may lead to a situation when the accumu-
lator will not reach its nominal capacity.
