Maintenance

8.1

Housing

No special maintenance is required for the housing. Keep outside
surfaces clean. Use a slightly dampened cloth and/or a special purifier for
synthetic material for cleaning. Avoid the use of cleansers, abrasives and
solvents.
!
Attention!
For the following reasons, the housing may not be opened by the
operator:
– Unexpected problems may occur during reassembly.
– Sealing requirements are no longer fulfilled.
Device Return and Environmentally Compatible 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 not subject to the RoHS directive.
We identify our electrical and electronic devices (as of August
2005) in accordance with WEEE 2002/96/EG and ElektroG with
the symbol shown to the right per DIN EN 50419 .
These devices may not be disposed with the trash. Please con-
tact our service department regarding the return of old devices.
I
f you use batteries or rechargeable batteries in your instrument or accesso-
ries which no longer function properly, they must be duly disposed of in

Battery Operation

When only one solid segment remains in the battery symbol, the batteries
must be replaced, or recharged if rechargeable batteries are used.
!
Attention!
Before opening, the instrument must be completely disconnected
from all external electrical circuits!
Check the batteries at short, regular intervals or after lengthy periods of
storage to make sure no leakage has occurred. If leakage has occurred,
the electrolyte must be carefully and completely removed from the instru-
ment with a damp cloth before new batteries are installed.
Charging the Batteries
!
Attention!
Use only the Z501N battery charger with safe electrical isolation
and a nominal secondary voltage of 9 V DC to recharge the bat-
teries. Before connecting the battery charger to the charging
socket at the instrument, make sure of the following points:
– Rechargeable batteries have been installed (not normal batteries).
– The instrument has been disconnected from the measuring
circuit at all poles.
– The voltage selector at the charger has been set to 9 V.
Connect the Z501N battery charger to the charging socket with the
3.5 mm jack plug. Set the voltage selector switch at the Z501N to 9 V.
Switch the test instrument on. The test instrument recognizes the fact that
a battery charger has been connected and starts the charging cycle. The
5 segments of the battery symbol are continuously displayed in a sweep-
ing pattern from left to right for the entire duration of the charging cycle.
Depleted batteries require a charging cycle of approximately 14 hours. If
Pb Cd Hg
the batteries are exhausted to a great enough extent, the test instrument
can no longer be switched on. If this is the case, leave the test instrument
connected to the activated battery charger for about 30 minutes, and then
proceed as described above.
