Operating conditions
The instruments are destined for use in dry clean rooms. Ope-
ration in an environment with high dust content, high humidity,
danger of explosion or chemical vapors is prohibited.
Operating temperature is 0 .. +40 degrees C. Storage or trans-
port limits are –10 .. +70 degrees C. In case of condensation two
hours are to be allowed for drying prior to operation.
For safety reasons operation is only allowed from 3 terminal
connectors with a safety ground connection or via isolation
transformers of class 2. The instrument may be used in any
position, however, suffi cient ventilation must be assured as
convection cooling is used. For continuous operation prefer a
horizontal or slightly upward position using the feet.
Do not cover either the holes of the case nor the
cooling fi ns.
Nominal specs are valid after a warm-up period of min. 20 min.
in the interval of +15 to +30 degrees C. Values without a toleran-
ce are typical of an average production instrument. STOP
Warranty and Repair
HAMEG instruments are subjected to a strict quality control.
Prior to leaving the factory, each instrument is burnt-in for
10 hours. By intermittent operation during this period almost
all defects are detected. Following the burn-in, each instru-
ment is tested for function and quality, the specifi cations are
checked in all operating modes; the test gear is calibrated to
national standards.
The warranty standards applicable are those of the country
in which the instrument was sold. Reclamations should be di-
rected to the dealer.
Only valid in EU countries
In order to speed reclamations customers in EU countries may
also contact HAMEG directly. Also, after the warranty expired,
the HAMEG service will be at your disposal for any repairs.
Return material authorization (RMA):
Prior to returning an instrument to HAMEG ask for a RMA
number either by internet (http://www.hameg.com) or fax. If
you do not have an original shipping carton, you may obtain
one by calling the HAMEG sales dept (+49-6182-800-300) or
by sending an email to vertrieb@hameg.com.
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 ben-
zine (petrol ether). Displays and windows may only be cleaned
with a moist cloth.
Do not use alcohol, solvents or paste. Under no cir-
cumstances any fl uid should be allowed to get into
STOP STOP the instrument. If other cleaning fl uids are used
damage to the lacquered or plastic surfaces is pos-
sible.
Line voltage selector
The instrument is desti-
ned for opera-tion on 115
or 230 V mains, 50/60 Hz.
The proper line voltage
is selected with the
line voltage selector. It is
necessary to change the
fuse ob-serving the pro-
per values printed on the
back panel.
Change of fuse
The mains fuse is accessible on the back panel. A change of
the fuse is only allowed after the instrument was disconnected
from the line and the power cord removed. Fuse holder and
power cord must not show any sign of damage. Use a screw
driver to loosen the fuse holder screw counterclockwise while
pressing the top of the fuse holder down. The top holding the
fuse will then come off. Exchange the defective fuse against a
correct new one. Any „repair" of a defective fuse or brid-ging
is dangerous and hence prohibited. Any damages to the in-
strument incurred by such manipulations are not covered by
the warranty.
Type of fuse:
5 x 20 mm; 250V~, C;
IEC 127/III; DIN 41662
(DIN 41571/3).
