The Rear Panel
Figure 6 Rear Panel Overview
1. Curr Input Fuse
The multimeter uses two kinds of fuses for protecting high and low currents and
both fuses were already installed before leaving factory. The current into 10 A
cannot exceed 13.5 A, otherwise it will blow out the internal fuse; while the
current into LO Sense/200 mA terminal cannot exceed 300 mA, otherwise the
current fuse from the rear panel may be blown out. To replace the low current
fuse, please:
1) Cut off the power supply.
2) Pull out the fuse seat by turning a straight screwdriver counterclockwise as
shown in the figure.
3) Place a new specified fuse.
4) Reinstall the fuse seat into the slot.
NOTE: The high current fuse stands inside the multimeter and is not
allowed to be replaced by users themselves. If such work must be
done, send your multimeter back to the factory.
