C-2 TP04300 Series Interface & Applications Manual
FLWM 4300: Sets the main air flow rate in scfm. The TP04300A tries to
hold this value constant under all operating conditions.
4000: Sets the maximum main air flow rate in scfm. The steady-
state air flow rate will typically be about 2/3rds of this value.

4300: The ramp mode on/off command is accepted but ignored
because the TP04300A can only ramp when cycling.
4000: This command switches the system to the ramp/cycle screen.
The TP04000A can ramp to a temperature even when not cycling.
SFIL 4300: A delay of 2 seconds must be inserted after the setup file
load command to permit it to complete.
4000: No explicit delay after this command is necessary because
the next command will not be executed until this command
completes.
TESR? 4300: Bit 7 is not used. No indication is given if datalogging shuts
down unexpectedly. (Datalogging is done to the hard disk, so a
shutdown is unlikely to occur.)
4000: Bit 7 is set to 1 if datalogging shuts down unexpectedly (due
to the floppy disk filling up).
WHAT? 4300:
5 = Operator screen.
6 = Cycle screen.
4000:
WHAT? returns many other values (which indicate which menu is
being displayed) in addition to the two listed above.
The TP04300A takes about 100 ms to process a command string. Putting multiple
commands (separated by semicolons) in a single string speeds processing considerably.
The TP04000A processes a command string in as little as 10 ms. Putting multiple
commands in a single string does not significantly speed processing.
