The side edges of the top cover are located in slots in both

corners.
To access the I+ and I- Terminal Fuses, remove the top
cover as follows:
i. Release the four screws securing the two rear-corner

c. Calibration Seal
Caution!
With the cover removed, a 'Calibration seal' can be seen
covering a countersunk screwhead on the left side of the
chassis assembly, at the top. This is one of the securing
screws for the top guard shield. The seal is set in position
following a calibration of the instrument, so that removal
of the guard shield can be detected.
The calibration seal must NOT be broken unless the
guard shield is to be removed for Authorized work inside
the chassis assembly. Removal of the guard shield will
compromise the traceable calibration of the instrument,
and a full recalibration of the 9100 will be required.
d. Locate the Fuses
The fuses are located at the left front of the top guard
shield, beneath the ribbon cable which links to the
Interconnection PCB on the rear panel, and protruding
through grommets in the guard shield (Fig 8.2.3).
