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) 0,8A.

The oscilloscope may only be operated from mains outlets with 
a safety ground connector. The plug has to be installed prior to 
connecting any signals. It is prohibited to separate the safety 
ground connection. 
Most electron tubes generate X-rays; the ion dose rate of this in-
strument remains well below the 36 pA/kg permitted by law.
In case safe operation may not be guaranteed do not use the 
instrument any more and lock it away in a secure place. 

Safe operation may be endangered if any of the following 
was noticed:

–   in case of visible damage.
–  in case loose parts were noticed
–  if it does not function any more.
–  after prolonged storage under unfavourable  conditions (e.g. 

like in the open or in moist atmosphere).

–  after any improper transport (e.g. insuffi cient packing not 

conforming to the minimum standards of post, rail or trans-
port fi rm)

Proper operation

Please note: This instrument is only destined for use by person-
nel well instructed and familiar with the dangers of electrical 
measurements. For safety reasons the oscilloscope may only 
be operated from mains outlets with safety ground connector. 
It is prohibited to separate the safety ground connection. The 
plug must be inserted prior to connecting any signals.

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 l the 
safety class II. The measurement category of such probes must 
be checked and observed.

Measurement categories

The measurement categories were derived corresponding to 
the distance from the power station and the transients to be 
expected hence. Transients are short, very fast voltage or cur-
rent 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 connec-

ted to the mains (household appliances, power tools etc).

Measurement CAT I:

 Electronic instruments and circuits which 

contain circuit breakers resp. fuses. 

Environmental conditions

The oscilloscope is destined for operation in industrial, business, 
manufacturing, and living sites.
Operating ambient temperature: +5 °C to +40 °C. During 
transport or storage the temperature may be –20 °C to +70°C. 
Please note that after exposure to such temperatures or in 
case of condensation proper time must be allowed until the 
instrument has reached the permissible temperature, resp. 
until the condensation has evaporated before it may be turned 
on! Ordinarily this will be the case after 2 hours. The oscillo-
scope is destined for use in clean and dry environments. Do 

not operate in dusty or chemically aggressive atmosphere or if 
there is danger of explosion. 
The operating position may be any, however, suffi cient ventila-
tion must be ensured (convection cooling). Prolonged operation 
requires the horizontal or inclined position. 

STOP

 Do not obstruct the ventilation holes!

Specifi cations are valid after a 30 minute warm-up period 
between 15 and 30 degr. C. Specifi cations without tolerances 
are average values.

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 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 
directed 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 service dept (++49 (0) 6182 800 500) or by 
sending an email to [email protected]

Maintenance

Clean the outer shell using a dust brush in 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, there after wipe the surfaces with a dry cloth. Plastic 
parts should be treated with an antistatic solution destined 
for such parts. No fl uid may enter the instrument. Do not use 
other cleansing agents as they may adversely affect the plastic 
or lacquered surfaces.

Line 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 undama-
ged, 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.
