Maintenance – Calibration
Attention!
!
Use specified fuses only!
If fuses with other blowing characteristics, other current
ratings or other breaking capacities are used, the operator
is placed in danger, and protective diodes, resistors and
other components may be damaged.
The use of repaired fuses or short-circuiting the fuse holder
is prohibited.
Note
Testing the Fuse with the Instrument Switched On
After inserting the fuse with the instrument switched on, the
instrument must be switched off briefly and then switched
back on, or briefly switched to a non-current measuring
range and then back to the “A” measuring range.
If contact is poor or the fuse is blown, FUSE appears at the
display.

4 Housing Maintenance
No special maintenance is required for the housing. Keep outside
surfaces clean. Use a slightly dampened cloth for cleaning. Avoid
the use of cleansers, abrasives or solvents.
9.5 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 WEEE
directive. Furthermore, we make reference to the fact that the
cur-rent 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 ac-
cordance with WEEE 2012/19/EU and ElektroG with
the symbol shown at 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 page 4).
If you use batteries or rechargeable batteries in your instrument or
accessories which no longer function properly, they must be duly
disposed of in compliance with the applicable national regula-
tions.
Batteries or rechargeable batteries may contain harmful sub-
stances or heavy metal such as lead (PB), cadmium (CD) or mer-
cury (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
Pb Cd Hg
provided for this purpose.
