Troubleshooting
No comm link error
A “No Comm Link” error indicates that the front panel processor has stopped communi-
cating with the main processor, which is located on the digital board. This error indicates
that one of the main processor ROMs may require re-seating in its socket. ROMs may be
reseated as follows:
1. Turn off the power, and disconnect the line cord and all other test leads and cables
from the instrument.
2. Remove the case cover as outlined in Section 5.
3. Remove the analog board assembly as outlined in Section 5.
4. Locate the two firmware ROMS, U15 and U16, located on the digital board. These
are the only ICs installed in sockets. (Refer to the component layout drawing at the
end of Section 6 for exact locations.)
5. Carefully push down on each ROM IC to make sure it is properly seated in its
socket.
CAUTION
Be careful not to push down excessively; digital board could crack.
6. Connect the line cord, and turn on the power. If the problem persists, additional
troubleshooting will be required.
