Autocorrection Feature
During ramping, the difference between the target and measured temperatures may
be observed to drift in an almost linear manner. The tracking error may start low and
gradually increase during the ramp. The autocorrection feature compensates for this by
internally adding a small offset and slope correction to the target temperature value.
To turn on the autocorrection feature, type A+<enter>. To turn off the autocorrection
feature, type A-<enter>.
Shut Down Procedure
VICI recommends that the FTC be shutdown when not in use. To shut down the FTC:
1. TypeZ-<enter> to turn off power to the column.
2. Unplugthepowercordfromthe110VACoutlettopowerdowntheFTC.
3. ExitHyperTerminal
