17. Replacing a Fuse
Warning
To avoid personnel injury or damage to the meter, use only the specified replacement fuse. F1 the specifi-
cation is 63mA 250V and F2 is 0.5A 250V, which are fast-melt.
0.5A 250V-fuse (F2) protection is in the current input jack, while 63mA 250V-fuse (F1) protection is in the
current output jack. To check whether fuses are blown:
• Turn the rotary function switch to mA.
• Plug the black test into COM, and the red test lead into the mA jack.
• Using an ohmmeter, check the resistance between the meter test leads .If the resistance is about 1Ω,
the fuse is good. An open reading means that fuse F2 is blown.
• Fuse F1 is blown if the outputs do not alter with the change of the fixed value, and replace it as follows:
1. Remove the test leads from the meter and turn the meter OFF.
2. With a standard blade hand screwdriver, turn each battery door screw counterclockwise so that the
slot is parallel with the screw picture molded into the case.
3. Replace the blown fuse(s).
4. Reinstall the meter.
