connectors with a safety ground connection or via isolation
transformers of class 2. The instrument may be used in any
position, however, sufficient ventilation must be assured as
convection cooling is used. For continuous operation prefer
a horizontal or slightly upward position using the feet.
Specifications with tolerances are valid after a 30 minute
warm-up period and at 23 degrees C. Specifications without
tolerances are typical values of an average instrument.
1.7 Warranty and Repair
Our instruments are subject to strict quality controls. Prior to
leaving the manufacturing site, each instrument undergoes
a 10-hour burn-in test. This is followed by extensive func-
tional quality testing to examine all operating modes and to
guarantee compliance with the specified technical data. The
testing is performed with testing equipment that is calibrat-
ed to national standards. The statutory warranty provisions
shall be governed by the laws of the country in which the
product was purchased. In case of any complaints, please
contact your supplier. Any adjustments, replacements of
parts, maintenance and repair may be carried out only by
authorized technical personnel. Only original parts may
be used for replacing parts relevant to safety (e.g. power
switches, power transformers, fuses). A safety test must
always be performed after parts relevant to safety have been
replaced (visual inspection, PE conductor test, insulation
resistance measurement, leakage current measurement,
functional test). This helps ensure the continued safety of
the product.
1.8 Maintenance
The instrument does not require any maintenance. Dirt may
be removed by a soft moist cloth, if necessary adding a mild
detergent. (Water and 1 %.) Grease may be removed with
benzine (petrol ether). Displays and windows may only be
cleaned with a moist cloth.
Do not obstruct the ventilation holes!
The product may only be opened by authorized and
qualified personnel. Prior to working on the product or
before the product is opened, it must be disconnected
from the AC supply network. Otherwise, personnel will
be exposed to the risk of an electric shock.
Before cleaning the measuring instrument, please make sure that
it has been switched off and disconnected from all power supplies
(e.g. AC supply network or battery).
No parts of the instruments may be cleaned with chemical clean-
ing agents (such as alcohol, acetone or cellulose thinner)!
1.9 Mains voltage and Changing the line fuse
A main voltage of 115 V and 230 V can be chosen. Please
check whether the mains voltage used corresponds with
the voltage indicated by the mains voltage selector on the
rear panel. If not, the voltage has to be changed. In this case
the line fuse has to be changed, too.
The fuses are accessible from the outside and contained in
the line voltage connector housing. Before changing a fuse
disconnect the instrument from the line, the line cord must
be removed. Check fuse holder and line cord for any dama-
ges. Use a suitable screw driver of appr. 2 mm to depress
the plastic fuse holder releases on both sides, the housing
is marked where the screw driver should be applied. After
its release the fuse holder will come out by itself pushed for-
ward by springs. The fuses can then be exchanged, please
take care not to bend the contact springs. Reinsertion of the
fuse holder is only possible in one position and by pressing
against the springs until the locks engage. It is forbidden to
repair defective fuses or to bridge them by any means. Any
damage caused this way will void the warranty.
Types of fuses:
Size 5 x 20 mm; 250V~,
IEC 60127-2/5
EN 60127-2/5
Line voltage
Correct fuse type
230 V
2 x 2,5 A slow blow
115 V
2 x 5 A slow blow
After changing the main voltage, the line fuse has to be changed.
Otherwise the instrument may be destroyed.
