Chapter 3. Operation
During programming of the
ADVAN option in the SETUP
submenu (see the
Programming Manual
), a
Static Density?
prompt requires a response. If a
YES
response is given, all of the options listed in Table 3-2 above are available. However,
if a
NO
response is given, the three options indicated do not appear and the
DIAG
option will appear in the
[F2]
position on the second option bar screen.
By following the instructions in this section, the Model GC868 can be set up to display
the desired channel option (for a 2-Channel meter) and the desired measurement
parameter. To utilize the more advanced display capabilities of the Model GC868,
refer to the
Programming Manual
and/or the
Service Manual
for the instrument.
