5.1.2
Recharging the Batteries
Attention!
!
Use only the charger (Z507A) which is offered as an op-
tional accessory for this instrument to charge the
batter-
ies
inserted in the instrument.
Make sure that the following conditions have been fulfilled be-
fore connecting the charger to the charging socket:
– rechargeable batteries have been inserted with correct
polarity,
no
normal batteries
– The test instrument has been disconnected from the
measuring circuit at all poles
– The instrument must remain off during charging.
Recharging of the batteries begins as soon as the charger is con-
nected to the mains and to the charging socket (see figure 2.1).
Charging takes approximately 5 hours and 30 minutes (integrated
safety timer) if the batteries have been fully depleted.
Safety Precautions
•
Do not attempt to recharge alkaline batteries: they may leak,
explode etc. The test instrument may be severely damaged or
destroyed as a result.
•
After initially charging new batteries and after rechargeable
batteries have not been used for a lengthy period of time (sev-
eral months), operating hours after charging may be signifi-
cantly less than usual. If this is the case, repeat the charging
procedure several times.
Autonomous, intelligent charging stations execute charging/
discharging cycles of this sort automatically (see instructions
included with the charging station). This procedure increases
the capacity of the batteries, thus making longer periods of
operation possible between charging cycles.
•
If no improvement is achieved in this way, one or more of the
rechargeable batteries may no longer fulfill the original specifi-
cations. If this is the case, the defective rechargeable battery
should be identified, e.g. with the help of the voltage measure-
ment, and replaced.
•
Battery capacity is gradually reduced as a result of long and
frequent use. When you notice that this is the case, all of the
rechargeable batteries should be replaced.
5.2
Cleaning
Use a soft cloth and soapy water for cleaning. Do not place the
test instrument back into service until its surface is completely dry.
Attention!
!
Do not use cleaning agents which contain benzine or al-
cohol! Prevent liquids from penetrating into the test in-
strument’s interior.
5.3
Recalibration
The measuring tasks performed with your instrument, and the
stressing it’s subjected to, influence aging of its components and
may result in deviation from the specified levels of accuracy.
In the case of strict measuring accuracy requirements, as well as
in the event of use at construction sites with frequent stress due
to transport and considerable temperature fluctuation, we recom-
mend a relatively short calibration interval of once per year. If your
instrument is used primarily in the laboratory and indoors without
considerable climatic or mechanical stressing, a calibration inter-
val of once every 2 to 3 years is sufficient as a rule.
During recalibration at an accredited calibration laboratory
(DIN EN ISO/IEC 17025), deviations from traceable standards
demonstrated by your measuring instrument are documented.
Ascertained deviations are used to correct display values during
later use of the instrument.
We would be happy to perform DAkkS or factory calibration for
you at our calibration laboratory. Further information is available at

Recalibration of your instrument at regular intervals is essential for
the fulfillment of requirements according to quality management
systems per DIN EN ISO 9001.
* Examination of the specification, as well as adjustment, are not included
in calibration. However, in the case of our own products, any required
adjustment is performed and adherence to the specification is con-
firmed.
