FUSES

This instrument contains four fuses. All are accessible from the rear-panel. Two protect
the   AC   prime   power   input,   and   two   protect   the   internal   DC   power   supplies.   The
locations of the fuses on the rear panel are shown in the figure below:

AC FUSE REPLACEMENT

To physically access the AC fuses, the power cord must be detached from the rear
panel of the instrument. The fuse drawer may then be extracted using a small flat-head
screwdriver, as shown below:
