To avoid personnel injury or damage to the meter, use only the specified fuse. The specification is 6 3mA
250V fast-melt. 3mA 250V-fuse protection is in the mA current output terminal. To check whether fuses are blown:
•
Turn the rotary switch to
mA
•
Plug the black test into COM, and the red test lead into the mA input.
Use an ohmmeter to check the resistance between test leads .If the resistance is about 20Ω, the fuse is good. An open
reading means that fuse is blown. Replace the fuse as follows.
•
Remove the test leads from the meter and turn the meter OFF.
•
Take off the protector of the meter, remove the four screws by using a standard-blade screwdriver, and then take off
the cover.
•
Replace the blown fuse(s).
•
Reinstall the cover.
