8.3 Fuse Replacement
If the fuse blows, the LED will not light and the instrument will not operate. Replace
only with the correct value fuse. Refer to
Table 1 - Fuse Table
for fuse values.
The fuse is located on the rear panel adjacent to the power cord receptacle.
Remove the fuse holder assembly as follows:
1. Unplug the power cord from the rear of the instrument.
2. Insert a small screwdriver in the fuse holder slot (located between fuse holder
and receptacle).
When reinstalling fuse holder, be sure that the fuse is installed so that the correct
line voltage is selected. To verify this, check the inscription on the surface of the fuse
box. At the top left and bottom right corner, the line voltage rating is labeled along
with a small arrow. Pick the line voltage to use and match the arrow on the bottom
right corner. On the rear panel, there is also a label that says “LINE VOLT.” with an
arrow. Match the line voltage inscription of the fuse box to this arrow to select that
line voltage.
