7. Maintenance 

 

Turn off the meter and remove the test 
leads  before  you  service  or  clean  the 
device. 

Beyond  replacing  batteries  and  fuses,  do  not 
attempt  to  repair  or  service  your  meter  unless 
you are qualified to do so and have the relevant 
calibration,  performance  test,  and  service  in-
structions. 

 

7.1  Battery and fuse replacement 

 

Replace the battery as soon as the flat 
battery icon ( 

+  -

Remove  from  the  multimeter  any  bat-
teries which are flat or starting to disin-
tegrate. 

 

Also  remove  batteries  from  the  mul-
timeter if it has not been used for a long 
period of time. 

 

Turn off the meter and remove the test 
leads before opening the case. 

 

Loosen screws with suitable screwdriver and 
remove case bottom. 

 

Replace the battery or the fuse. 

 

Replace  the  case  bottom  and  reinstall  the 
three  screws.  Never  operate  the  meter 
unless the case bottom is fully closed. 

 

Do  not  dispose  of  the 
battery 

in 

regular 

household refuse. Fol-
low  the  local  regula-

Periodically wipe the case with a damp cloth 
and mild detergent. 

 

Do not use abrasives or solvents. 

Dirt or moisture in the measurement sockets can 
affect readings. 

 

Shake out any dirt that may be in the meas-
urement sockets. 

 

Soak a new swab with isopropyl alcohol and 
work  around  the  inside  of  each  measure-
ment socket. 

 
 

8. Disposal 

 

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  nor-
mal  domestic  waste. 
Local  regulations  for 
the  disposal  of  electri-
cal  equipment  will  ap-
ply. 

 

 

Do  not  dispose  of  the  battery  in  regular
