5. How to change the Fuse

Caution

①

Turn off the power supply to the terminal of this instrument.

②

Detach the screw (M2.6 x 5) of 4 points at the right side of the front panel, and remove the cover.

③

Replace the fuse (1 A) attached at the parts mounting side of PCB showing as follows.

④

Put the cover, and install the screw to 4 points.

●

When the procedure of installing the fuse, and the capacity of installed fuse is improper, it will cause an unexpected failure.
