Starting an
Experiment
Before you start the experiment, ensure that the
TGA 2950 is online with the controller and you
have entered all necessary experimental param-
eters.
Once the experiment is started, operations are
best performed at the controller keyboard. The
TGA 2950 is very sensitive to motion and might
pick up the vibration caused by pressing a key on
the instrument keypad.
Start the experiment by pressing the START key
on the instrument keypad, or selecting start on
the TGA Instrument Control program (see the
online help and documentation for further
information). When you press the START key,
the system automatically loads the sample pan
and closes the furnace if necessary, and then
runs the loaded method to completion.
Forced Start
If you wish to start collecting data during
instrument setup, you can use the forced start
feature. This is most useful for samples that
loose a significant amount of weight during the
set-up period (i.e., samples with volatile sol-
vents). When a forced start is initiated, the
current sample weight is stored as the initial
weight, data collection is started immediately,
and the instrument status changes from Set Up
to Started. The methods begin when the
normal set-up procedures are completed.
To begin a forced start, press START on the
instrument keypad while the status line displays
Set Up.
