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 
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 [email protected]

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 
fl uid 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 measure-
ment 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.

Measurement CAT IV: Measurements close to the power station, 
e.g. on electricity meters

Measurement CAT III: Measurements in the interior of buildings 
(power distribution installations, mains outlets, motors which 
are permanently installed). 

Measurement CAT II: Measurements in circuits directly con-
nected to the mains (household appliances, power tools etc). 

Measurement CAT I: Electronic instruments and circuits which 
contain circuit breakers or fuses.

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.

Type of fuse:

Size 5 x 20 mm; 250V~, C; IEC 127, Bl. III; DIN 41 662 (or DIN 41 
571, Bl. 3). Cut off: slow blow (T) 2A.
