Loading the
Samples
After you have done the taring procedures for all
of the empty sample pans, load the samples as
follows:
1. Place each sample in the correct sample pan
making sure that you do not switch around
the pans on the sample platform (they have
already been tared in the numbered posi-
tion).
2. Place the sample pans on the sample plat-
form in their original order. Make sure that
the wire on the bottom of the sample pans
align with the groove in the panhole, so that
the sample pan can be picked up by the
sample hang-down wire.
Always use the brass tweezers to handle the
sample pans.
Manually loading the sample pan onto the hang-
down wire may damage the balance mechanism.
3. Press the LOAD key. The TGA will auto-
matically load the selected sample.
4. Position the thermocouple at the edge of the
sample pan, rather than in the middle for the
best results (see Figure C.4).
The position of the thermocouple should be the
same as it was during temperature calibration.
