be removed from the device. The battery is 
replaced in accordance with 4.1. 

  If the multimeter remains idle over a long 

period of time, the battery should be re-
moved from the unit. 

  Do not dispose of the

lations (In Germany: 
BattG; EU: 
2006/66/EG). 

 

 

5.3  Replacing the fuse 

  The multimeter is equipped with a safety 

fuse FF 3, 15 A / 600 V, breaking capacity 
1.5 kA. To replace the fuse the device must 
be opened as described in section 4.1. Re-
move the fuse and replace it with a fuse of 
identical type. Then replace the section of 
housing and snap it back into place se-
curely.

  The packaging should be disposed of at 

local recycling points. 

  Should you need to 

dispose of the equip-
ment itself, never 
throw it away in normal 
domestic waste. Local 
regulations for the dis-
posal of electrical 
equipment will apply. 

 

  Do not dispose of the battery in the regular 

household garbage. Follow the local regula-
tions (In Germany: BattG; EU: 2006/66/EG).
