Weight Calibration
Weight calibration should be performed on the
TGA at least once a month. The weight calibra-
tion procedure calibrates both the 100 mg and
1 gram weight ranges. The calibration param-
eters are stored internally in the instrument.
You must be sure to determine the exact weight
of the calibration weights before they are used to
calibrate the instrument.
The Instrument Control weight calibration
functions guide you through the calibration
procedure step-by-step, see the online help and
documentation for further information.
Sample Platform
Calibration
The sample platform adjustment procedure is
used if the sample hang-down wire fails to pick
up a sample pan during an automatic loading
procedure. The sample platform must be
adjusted so that the instrument can properly load
and unload the sample pans.
To avoid weight signal noise, the TGA must be
level so that the sample pan and hang-down wire
hang inside the furnace and thermocouple tube
without touching them. The Instrument Control
sample platform adjust functions take you step-
by-step through the procedure, see the online
help and documentation for further information.
