SAFETY INFORMATION 

This multimeter has been designed according to IEC 

1010 

concerning electronic measuring instruments with an 
overvoltage category (CAT

) and pollution 2. 

Follow all safety and operating instructions to ensure that the 
meter is used safely and is kept in good operating condition. 
Full compliance with safety standards can be guaranteed only 
with test leads supplied. If necessary, they must be replaced 
with the type specified in this manual. 

 
SAFETY SYMBOLS 

 

 

Important safety information, refer to the operating 

manual.

 

 

Dangerous voltage may be present.

 

 

Earth ground.

 

 

Double insulation (Protection class II).

 

 

Fuse must be replaced with rating specified in the 

manual.

 

 
MAINTENANCE 

 

 

 

 

 
 

 

 

 

Before opening the case, always disconnect test leads 
from all energized circuits. 
For continue protection against fire; replace fuse only 
with the specified voltage and current ratings: 
        F 200mA/250V(Quick Acting) 
Never use the meter unless the back cover is in place 
and fastened completely. 
Do not use abrasives or solvents on the meter. To clean 
it using a damp cloth and mild detergent only.
