Checking The Fuse/Replacing The Fuse - VOLTCRAFT VC930 Notice D'emploi

d) Checking the Fuse/Replacing the Fuse
The current measuring ranges are protected by high-perfor-
mance fuses. If measuring in this range is no longer possi-
ble, you have to change the fuse.
The meter enables testing fuses when the casing is closed.
Proceed as follows for testing:
- Select the measuring range "Ω " on the rotary control.
- Insert the measuring lines into the "VΩ " socket.
- Touch the measuring prod to the current measuring jack
to the tested.
- If a measured value is displayed, the fuse is OK. If the
display continues to show "OL", the respective fuse is
defective and needs to be replaced.
Proceed as follows for fuse replacement:
- Disconnect the connected measuring lines from the
measuring circuit and the meter. Switch off the DMM.
- Open the casing as described in chapter "Opening the
Meter".
- Replace the defective fuse with a new one of the same type and rated current or one of the same build. The fuses
have the following values:
Fuse
Rated data
Switching capability 10kA
Dimensions
Type
- Close the casing again carefully.
Using mended fuses or bridging the fuse holder is not permitted for safety reasons. It may cause
fires or arc explosions. Never operate the meter when it is open.
