                                           Operating Instructions 

- 34 - 

8.5  Replacing the Fuse. 

 

 

Before  opening  the  DL9110  /  DL9118  ensure  that  it  is 
disconnected from all voltages! Electric shock danger! 

 

 

All  replacement  fuse  types  are  specified  for  ratings  and 
size  on  the  battery  compartment  cover  on  the  DL9110  / 
DL9118. 
 

 

Power the unit off by selecting the Off position on the rotary switch. 
 
Disconnect all the test leads from the unit. 
 
Position  the  DL9110  /  DL9118  face  down  and  release  the  captive  4 
screws in the battery compartment cover. 

 

Remove the battery compartment cover. 

 

Lift  one  end  of  the  fuse  out  of  the  fuse  holder  with  the  help  of  a  flat 
bladed screwdriver. 

 

Lift the defective fuse completely out of the fuse holder. 
 
Insert a new fuse as described and specified by the text on the battery 
compartment cover. 

 

Ensure that the new fuse is seated and centred in the fuse holder. 
 
Relocate the battery cover over the battery compartment and fasten in 
position with the battery cover captive screws. 

 

8.6  Service and Calibration. 

 
To  maintain  the  specified  accuracy  of  the  measurement  results,  the 
instrument  must  be  recalibrated  at  regular  intervals  by  either  the 
manufacturer  or  an  authorised  Service  Agent.  We  recommend  a 
recalibration period of one year.
