13.3 Drier working modes, drying time, sample t i m e
During the balance – drier operation sampling of the mass on the pan takes place.
Sampling time is set by the user, according to drying process speed. As a result of
sampling the current humidity value is calculated and displayed. Measurement is
finished depending on selected Drying mode:
1. In Time mode total humidity measurement time (Drying time) is defined by the user,
2. In Short mode humidity measurement is finished, when drying is stopped and
differences of a few successive mass samples are smaller than threshold value (2 mg).
Amount of successive samples taken into consideration is defined as Samples quantity.
Measurement is finished when Drying time is exceeded at the latest.

Drying chart in Short mode for Samples quantity = 3.
When choosing time mode only drying time and for example 10 times shorter sample
time is needed to start. In Short mode additionally Samples quantity is needed and
Samples interval should be carefully calculated – end of drying is based on this
parameter(and on Samples quantity).
