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.

  Do not cover either the holes of the case nor the 

cooling fins. 

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.

Warranty and Repair

HAmeG instruments are subjected to a rigorous quality control. 

Prior to shipment each instrument will be burnt in for 10 hours. 

Intermittent operation will produce nearly all early failures. 

After burn in, a final functional and quality test is performed 

to check all operating modes and fulfilment of specifications. 

The latter is performed with test equipment traceable to na-

tional measurement standards.

Statutory warranty regulations apply in the country where the 

HAmeG product was purchased. In case of complaints please 

contact the dealer who supplied your HAmeG product. 

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 fluid should be allowed to get into 

the instrument. If other cleaning fluids are used 

damage to the lacquered or plastic surfaces is pos-

sible. 

Mains voltage

A main voltage of 115V and 230V can be chosen. Please check 

whether the mains voltage used corresponds with the volta-

ge 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.

 

Please note:

 

After changing the main voltage, the line fuse has 

to be changed. Otherwise the instrument may be 

destroChanging the line fuse

Changing the line fuse

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 damages. 

Use a screw driver to loosen the fuse holder screw counter-

clockwise 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.

It is forbidden to repair defective fuses or to bridge them by any 

means. Any damage caused this way will void the warranty.
