4. MAINTENANCE
4.1. Batteries
Dangerous voltage in batteries compartment!
Disconnect both test tips from tested object and turn off the
instrument before removing the batteries compartment cover or
before connecting jack to the socket for accumulator charger!
The instrument must not be put into operation without the
batteries compartment cover properly fastened by both screws!
The instrument uses our AAA either alkaline cells or NiCD/NiMH accumulators.
The batteries/accumulators are continuously monitored, see description in the
Chapter 3.2. I batteries/accumulators are low, it must be replaced/charged.
4.1.1. Inserting and replacing the batteries / accumulators
Batteries/accumulators are inserted into the device by unscrewing two screws
and removing the batteries compartment cover, see Fig. 2.2. Then remove old
batteries/accumulators and insert new ones. Observe correct polarity:
Fig. 4.1 Correct batteries/accumulators polarity
Always replace all our batteries/accumulators. Use only high-quality types.
Then put the batteries compartment cover back and secure it with two screws.

GIGATESTpro
- 16 -
4.1.2. Charging of accumulators
For charging of accumulators use only adapter supplied as
optional accessories!
Accumulators are charged as soon as the adapter is connected to mains and to
socket or accumulators charger (see Fig. 2.1). I accumulators are ully
discharged, the charging takes about 6 hours (applies to batteries with a
capacity o 800 mAh). Prolonged charging is not a problem, however, do not
charge accumulators or more than 12 hours.
Notes:
•Do not charge alkaline cells – it may lead to explosion, leakage, etc. This can
cause serious damage or destruction o instrument.
•During charging o new accumulators or ones that were unused or a longer
period ( ew months) unpredictable chemical processes may arise. As a result,
the instrument operation time can be signi icantly reduced. In this case, we
recommend several charge (with optional charger) / discharge (normal use o
the instruments) cycles.
Another way is to use a stand-alone intelligent charger which discharge /
charge each cell individually. The discharge / charge cycle is automatically
executed, see instruction manual or the charger used.
A ter the procedure, the capacity o the accumulators should return to normal.
The above described cycle in stand-alone intelligent charger is recommended
every ew months to make.
•I a ter several cycles o the above described discharge / charge capacity o
the accumulators does not return to normal, this may be due to the act that
the one or more accumulators are degraded - whereas, the built-in
accumulator charger charges all cells connected in series at the same time,
and even one bad (or just di erent) cell negatively a ects the entire
accumulator pack.
It may result in uneven charging o cells, excessive heating o the cell(s)
during charging etc.
In this case, we recommend that a aulty cell is identi ied with an intelligent
stand-alone charger, or at least comparing the voltage o each cell and then a
aulty cell replace with a new one.
•The above-described e ects can not be con used with a normal reduction in
accumulators’ capacity over time. All accumulators with a growing number o
charge / discharge cycles gradually loose capacity. This is normal, depending
on accumulator type, the number and parameters o the discharge / charge
cycles.

4.2. Clea i g
Disconnect both test tips from tested object and turn off the
instrument before cleaning!
Wait until the instrument becomes totally dry before using it!
Use so t cloth, slightly moistened with lukewarm soap water or plastic case
cleaning. Do not spill cleaning liquid over the instrument!
Do not use cleaning liquids based on petrol, hydrocarbons etc.!
4.3. Calibratio
Measuring instruments should be regularly calibrated. We recommend interval o
calibration 1 year. Furthermore we recommend carrying out calibration a ter
each repair. Contact your local distributor or urther in ormation.
