Warranty And Repair; Mains Voltage - Hameg HMS 3000 Handbuch

1.5

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 instrument is
tested for function and quality, the specifi cations are checke-
din 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
directed to the dealer.
Only valid in EU countries:
In order to speed claims, 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 (+49
(0) 6182 800 501). If you do not have an original shipping carton,
you may obtain one by calling the HAMEG service dept (+49 (0)
6182 800 500) or by sending an email to service@hameg.com.
1.6 Maintenance
Clean the outer case using a dust brush at regular intervals.
Dirt can be removed from housing, handle, all metal and plastic
parts using a cloth moistened with water and 1 % detergent.
Greasy dirt may be removed with benzene (petroleum ether) or
alcohol. Thereafter wipe the surfaces with a dry cloth. Plastic
parts should be treated with a suitable antistatic solution. No
fluid may enter the instrument. Do not use other cleansing
agents as they may adversely affect the plastic or lacquered
surfaces.
1.7 CAT I
This oscilloscope is destined for measurements in circuits not
connected to the mains or only indirectly. Direct measurements,
i.e. with a galvanic connection to circuits corresponding to the
categories II, III, or IV are prohibited! The measuring circuits
are considered not connected to the mains if a suitable isolation
transformer fulfi lling safety class II is used. Measurements on
the mains are also possible if suitable probes like current probes
are used which fulfi ll the safety class II. The measurement
category of such probes must be checked and observed. The
measurement categories were derived corresponding to the
distance from the power station and the transients hence to
be expected. Transients are short, very fast voltage or current
excursions which may be periodic or not.
1.8

Mains voltage

The instrument has a wide range power supply from 105 to
253 V, 50 or 60 Hz ±10%. There is hence no line voltage selector.
The line fuse is accessible on the rear panel and part of the line
input connector. Prior to exchanging a fuse, the line cord must
be pulled out. Exchange is only allowed if the fuse holder is
undamaged. It can be taken out using a screwdriver put into the
slot. The fuse can be pushed out of its holder and exchanged.
The holder with the new fuse can then be pushed back in place
against the spring. It is prohibited to "repair" blown fuses or to
bridge the fuse. Any damages incurred by such measures will
void the warranty.
