b) 15 Amp Fast acting 6.3x32mm Ceramic Fuse (by a professional 

person only)

 Turn off the meter and disconnect 

both test leads.

 Remove the three screws at the back 

of the case (one at the top and two at 

the bottom).

 Remove the single screw securing 

the battery/fuse cover and lift to 

open.

 Remove the batteries.

 Carefully lift the top of the case away 

from the bottom.

 

CAUTION: 

Lift the top case 

carefully - do not break the 

wires attached to the battery 

compartment.

 Gently lift the battery compart-

ment and move it through the 

hole on the inner side of the meter. 

 The 15 amp fuse is the larger  

fuse on the bottom of the PC board,  

which should now be in full view. Carefully remove the old fuse and 

replace it with a new CSA/UL listed fast acting ceramic 15A/250V fuse 

only.
