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.
