USER MANUAL 27
14. Proper moisture
Before measurement carefully prepare the sample (as described in chapter Description
of Thermogravimetric Analysis) and set correct drying parameters (see the diagram in
chapter 11.6, description of the way of settting is in 11.4).
Place an empty single-use pan and
tare the balance with
T
key.
The indication should be m=0,000g.
Open the drying chamber and using
the pan handle place the single-use
pan with the sample on the pan
support. Close the chamber.
Start the measurement choosing
START key.
In the lower line the time left to end
the measurement and successive
measurement number is displayed.
Drying in progress is signalised with
alternating SAMPLE /DRYING
communicate.
Wait until END communicate
appears. Now read the result.
Attention: No STB communicate and m0 sign in negative, marks acceptance of unstable
initial mass value m0, caused by pressing the pan to chamber wall or by too fast sample
drying, which can cause to measurement failures.
