There is a second fuse with a fuse holder located in the rear panel of the multimeter. This is an
overcurrent protection fuse for the low current measurement input. It is a 5 x 20 mm 250 V, 3.15 A
slow blow 50T glass fuse.
A third fuse is located inside the instrument which protects the 10 A input terminal if the input current
exceeds the maximum rating. It is a 6 x 32 mm 250 V, 12 A fast blow fuse.
2.3 Carrying Handle Adjustment
To adjust the position, grasp the handle on both sides of the instrument at the pivot point and rotate
the handle to the desired position. Be sure the handle locks in its new position.
Handle transport position
Be sure the handle is locked in position and avoid
twisting movements while transporting as the handle
can damage and drop the instrument.
To remove the fuse holder and access the fuse, use a flat head screw driver and
turn counter-clockwise. Similarly, push the fuse holder inward and turn clockwise
to replace the fuse.
