3. GENERAL SAFETY RULES

Great attention has been paid to the safety aspect in 
designing this device. Any change or extension in the 
device can compromise the safety. This would even 
render the warranty void and ineffective.

• 

Ensure order at the work place.

-  A disorderly workplace can cause accidents.- En-

sure suf

fi

 cient illumination at the workplace.

• 

Pay attention to the environmental factors.

•  Do not use the multimeter in humid or wet sur-

roundings. Protect the multimeter from rain and 
humidity.

• 

Keep children away from it.

•  Keep other persons away from the work area and 

ensure that they do not touch the multimeter.

• 

Store the device in a safe place. Multimeters, which 
are not used for a while, must be stored in a dry 
room.

•  Do not overload the multimeter. Work within the 

indicated working range: this is better and safer. 
Damages caused by overloading do not fall within 
the purview of the guarantee.

• 

Do not use the instrument leads improperly. Do not 
carry the device suspended by the instrument leads 
and do not pull the plug from the multimeter by the 
instrument leads; always pull on the plug itself.

• 

Service the multimeter with care.

• 

Keep the multimeter clean. This facilitates workand 
augments the safety. See that the multimeter does 
not come in contact with humidity, oil or fat.

•  Pull the plugs out of the instrument leads from the 

multimeter, when the multimeter is not in use.

• 

Check if the device is damaged.

• 

Before using the device, recheckwhetherthe device 
and instrument leads are in proper condition and 
function correctly.

4. SPECIAL SAFETY RULES

1.  WARNING! Measuring high voltages and currents 

poses a life hazard. Never touch exposed metallic 
parts of the instrument leads.

2.  The multimeter is sensitive. Protect it from vibra-

tions and do not let it fall down.

3.  If the multimeter is not going to be used for a time, 

please switch it OFF to save on batteries.

4.  If the multimeter is not gong to be used for a long 

period, remove the battery in order to avoid spill-
ing.

5.  Do not subject the device to high humidity or high 

temperatures.

6.  Keep the multimeter away from strong magnetic 

fi

 elds.

7.  Remove the instrument leads immediately if you 

smell burnt cable insulation.

8.  Use the multimeter only if the housing is closed.
9.  Use the multimeter only for measurements of the 

class I or II.

Do not use the multimeter for measurements in the 
class III or IV.

5. ENVIRONMENTAL PROTECTION

Raw material recovery is better than garbage disposal. 
To avoid damages in transport, the device must be de-
livered in solid packing made mostly from recyclable 
material such as paper, pulp and wood. We therefore 
recommend that you recycle the packing as far as pos-
sible.

The multimeter is operated on batteries. Dis-
pose of spent batteries as stipulated.
