REPLACING THE FUSE

If the multimeter does not work, you might need to replace the fuse with the supplied 315 mA, 250V ceramic fuse. The spare fuse is next to the battery compartment.

Caution: Do not use a fuse with rat- ings other than those specified here. Doing so might damage your multim- eter.

Follow these steps to replace the fuse.

1.Set the function selector to OFF, then disconnect the test leads if they are connected.

WARNING: TO AVOID ELEC- TRIC SHOCK, YOU MUST DIS- CONNECT THE TEST LEADS BEFORE YOU REMOVE THE BACK COVER.

2.Use a Phillips screwdriver to remove the screw on the upper back of the multimeter. Then remove the top cover.

3.Use a Phillips screwdriver to remove the screw on the lower back of the multimeter, then remove the multimeter’s back cover.

4.Remove the battery.

5.To remove the fuse, gently pull the red ribbon holding it. The fuse pops out.

6.If the fuse is blown, discard it and save the ribbon (to use with the next spare fuse you store in the compartment). Then remove the spare fuse and the ribbon hold- ing it from the upper back of the multimeter and insert it into the fuse holder.

7.Replace the battery in the com- partment.

Warning: Do not operate your multimeter until the back cover and top cover are in place and secured.
