See section 4.6.
20.2 Rechargeable Battery Operation, and Charging
Check to make sure that no leakage has occurred at the
rechargeable batteries at short, regular intervals, or after the
instrument has been in storage for a lengthy period of time.
Note
Prior to lengthy periods of rest (e. g. holiday), we recom-
mend removing the rechargeable batteries. This helps to
prevent excessive depletion or leakage of batteries,
which, under unfavourable circumstances, may cause
damage to the instrument.
If battery voltage has fallen below the allowable
lower limit, the pictograph shown at the right
appears. “Low Batt!!!” is also displayed along with a battery icon.
The instrument does not function if the batteries have been
depleted excessively, and no display appears.
Attention!
!
Use only the charger Z502R to charge the Kompakt Akku-
Pack Master (Z502H) which has already been inserted into
the test instrument.
Make sure that the following conditions have been fulfilled be-
fore connecting the charger to the charging socket:
– Kompakt Akku-Pack Master (Z502H) has been
installed, no commercially available battery packs, no
individual rechargeable batteries, no standard batteries
– The test instrument has been disconnected from the
measuring circuit at all poles
– The instrument must remain off during charging.
If the batteries or the battery pack (Z502H) have not been used or
recharged for a lengthy period of time (> one month), thus result-
ing in excessive depletion:
Observe the charging sequence (indicated by LEDs at the char-
ger) and initiate a second charging sequence if necessary (dis-
connect the charger from the mains and from the test instrument
to this end, and then reconnect it). Please note that the system
clock stops in this case and must be set to the correct time after
the instrument has been restarted.
20.2.1 Charging Procedure with Charger for Z502R
➭ Insert the correct mains plug for your country into the charger.
Attention!
!
Make sure that Kompakt Akku Pack Master (Z502H) has
been inserted, no battery holder.
For charging in the tester, only use Kompakt Akku Pack Master (Z502H),
which is either included in the standard equipment or available as an
accessory, with heat-sealed battery cells.
➭ Connect the charger to the test instrument with the jack plug,
and then to the 230 V mains with the interchangeable plug.
(The charger is suitable for mains operation only!)
Attention!
!
Do not switch the test instrument on during charging.
This might affect the charging process.
➭ Please refer to the operating instructions included with the
charger regarding the meanings of LED displays during the
charging process.
➭ Do not disconnect the charger from the test instrument until
the green LED (charged/ready) lights up.
20.3 Fuses
If a fuse has blown due to overload, a corresponding message
error appears at the display panel. The instrument’s voltage mea-
suring ranges are nevertheless still functional.
Replacing the Fuse
Attention!
!
Disconnect the device from the measuring circuit at all
poles before opening the fuse compartment lid!
➭ Loosen the slotted screws at the fuse compartment lid next to
the mains power cable with a screwdriver. The fuses are now
accessible.
➭ Replacement fuses can be accessed after opening the battery
compartment lid.
Attention!
!
Severe damage to the instrument may occur if incorrect
fuses are used.
Only original fuses from GMC-I Messtechnik GmbH may
be used (order no. 3-578-285-01 / SIBA 7012540.3.15
SI-EINSATZ FF 3.15/500 6.3X32).
Only original fuses assure required protection by means
of suitable blowing characteristics. Short-circuiting of
fuse terminals or the repair of fuses is prohibited, and is
life endangering!
The instrument may be damaged if fuses with incorrect
ampere ratings, breaking capacities or blowing charac-
teristics are used!
➭ Remove the defective fuse and insert a new one.
➭ Insert the fuse compartment lid after the fuse has been re-
placed and secure it by turning clockwise.
20.4 Housing
No special maintenance is required for the housing. Keep outside
surfaces clean. Use a slightly dampened cloth for cleaning. In par-
ticular for the protective rubber surfaces, we recommend a moist,
lint-free microfiber cloth. Avoid the use of cleansers, abrasives or
solvents.
Return and Environmentally Sound Disposal
The instrument is a category 9 product (monitoring and control
instrument) in accordance with ElektroG (German electrical and
electronic device law). This device is subject to the RoHS direc-
tive. Furthermore, we make reference to the fact that the current
status in this regard can be accessed on the Internet at
www.gossenmetrawatt.com by entering the search term WEEE.
We identify our electrical and electronic devices in accor-
dance with WEEE 2012/19/EU and ElektroG with the
symbol shown to the right per DIN EN 50419. These
devices may not be disposed of with the trash. Please contact
our service department regarding the return of old devices (see
address in section 22).
If the (rechargeable) batteries used in your instrument are depleted,
they must be disposed of properly in accordance with valid
national regulations.
Batteries may contain pollutants and heavy metals such as lead
(Pb), cadmium (Cd) and mercury (Hg).
The symbol to the right indicates that batteries must not
be disposed of with the trash, and must be brought to a
designated collection point.
