Appendix C: Changing the fuse 

 

Warning: To avoid electrical shock or damage to the multimeter, ensure 

that the insides of the casing stay dry at all times.   

Change the fuse: 

To change the fuse, perform the following 
steps: 

 

1.

 

Ensure that the rotary switch is at the 

 

position. Remove test leads and any 
connectors from the input terminals. 

2.

 

Remove the yellow protective cover. Most 
suitable to start is the place you can see in 
picture 1 (on the side of the Multimeter, at 
the same height as the rotary switch). 

3.

 

Proceed removing the protective cover – 
see picture 2. 

4.

 

Turn the device, to see the reverse side.   

5.

 

Loosen the screws (see picture 3) and 
remove the cover.   

6.

 

Now you can see both fuses (look 
at picture 4).   
Check them e.g. with another 
multimeter. 

7.

 

If damaged you must, change 
them. 
 
Fuse types: 
L = 32 mm / D = 6 mm 
15 A / 1000 V 

(order no. DG415-00)

 

1 A / 1000 V 

(order no. DG401-00)

 

Material: ceramic 

8.

 

Proceed in reverse order, to reassemble the device.
