Replacing Fuses
Ð Remove the cap for the respective fuse with the help of a suitable tool
(e.g. screwdriver) by pressing and turning counterclockwise.
Attention!
!
Incorrect fuses may cause severe damage to the test instrument.
Only original fuses from GMC-I Messtechnik GmbH
assure the required protection by means of suitable
breaking characteristics (article no. 3-578-222-02).
Bridging or repairing fuses is prohibited!
The instrument may be damaged if fuses with other current
ratings, blowing or breaking characteristics are used!
Ð Remove the defective fuse and replace it with a new replacement
fuse. Replacement fuses are located in the battery compartment.
Ð Insert the new fuse and the cap together, and lock into place by
turning clockwise.
Ð Replace the battery compartment cover and secure it with the
screws.
13.5 Housing
No special maintenance is required for the housing. Keep outside
surfaces clean. Use a slightly dampened cloth or a special purifier for syn-
thetic material for cleaning. Avoid the use of cleansers, abrasives and sol-
vents.
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 RoHS-compliant. 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 (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 of with the trash. Please contact our
service department regarding the return of old devices.
If you use batteries or rechargeable batteries in your instrument or accesso-
ries which no longer function properly, they must be duly disposed of in
compliance with the applicable national regulations.
Batteries or rechargeable batteries may contain harmful substances or
heavy metal such as lead (PB), cadmium (CD) or mercury (Hg).
They symbol shown to the right indicates that batteries or
rechargeable batteries may not be disposed of with the trash, but
must be delivered to collection points specially provided for this
purpose.
13.6 Recalibration
The respective measuring task and the stress to which your measuring
instrument is subjected affect the ageing of the components and may
result in deviations from the guaranteed accuracy.
If high measuring accuracy is required and the instrument is frequently
used in field applications, combined with transport stress and great tem-
perature fluctuations, we recommend a relatively short calibration interval
of 1 year. If your measuring instrument is mainly used in the laboratory and
indoors without being exposed to any major climatic or mechanical stress,
a calibration interval of 2-3 years is usually sufficient.
During recalibration* in an accredited calibration laboratory
(DIN EN ISO/IEC 17025) the deviations of your instrument in relation to
traceable standards are measured and documented. The deviations
determined in the process are used for correction of the readings during
subsequent application.
We are pleased to perform DAkkS or factory calibrations for you in our cal-
ibration laboratory. Please visit our website at
www.gossenmetrawatt.com ( Company DAkkS Calibration Center
or
FAQs Calibration questions and answers).
By having your measuring instrument calibrated regularly, you fulfill the
requirements of a quality management system per DIN EN ISO 9001.
*
Verification of specifications or adjustment services are not part of the calibration.
For products from our factory, however, any necessary adjustment is frequently
performed and the observance of the relevant specification is confirmed.
