11.7 Proper moisture analysis
Before measurement carefully prepare the sample (as described in chapter Description
of Thermogravimetric Analysis) and set correct drying parameters (see chapter Working
Parameters Setting).

Place an empty single-use pan and
tare the balance with T key.
Open the drying chamber and using

pan to chamber wall or by too fast
sample drying, which can cause to
measurement failures.
During the measurement the following information is displayed:
m0-m/m0*100% - mathematic formula used for calculations
T s – defined drying temperature
ts - defined drying time
T – current drying temperature
m – current weight
t – current drying time
m0 – initial weight
