Starting the Sequence
Before the column ramp sequence will start, the column must be turned on and there
must be a “ready” flag viewable in the data log, indicating that the equilibration time has
elapsed. As soon as the “ready” signal is received, the ramp sequence may be restarted by
typing GO<enter>.
Once the heating cycle is complete, the fan will be turned on to cool the column to the
stage 1 starting temperature. Once the state 1 temperature has been reached and the
ready flag appears in the data log, the sequence may be restarted by typing GO<enter>.
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
