Preparing the Agilent 11982A for Use
Figure 2-2. Opening the Fuse Holder Door
C A U T I O N
You must remove the voltage tumbler to change the voltage selector. Rotating
the voltage tumbler while it is in the line module damages the line module.
2 Remove the voltage tumbler (the voltage tumbler is not attached to the unit).
3 Replace the voltage tumbler so the desired line voltage value shows through
the small opening in the fuse holder door.
Checking the Fuse
The recommended fuse is a 0.5 A, 250 V, slow blow, Agilent Technologies part
number 2110-0202.
The line fuse is housed in a small container next to the voltage tumbler (see
Figure 2-3 on page 2-6 ). The spare fuse is stored below the line fuse.
To check the fuse, insert the tip of a screwdriver on the side of the container
and gently pull outward to remove the container.
If the fuse is defective or missing, install a new fuse in the proper position and
reinsert the fuse container.
