be selected by tests). Mild mode is recommended to drying samples of leather
structure.
QUICK mode
Quick mode is recommended to drying samples
that moisture content varies from 5%, and 15%.
In the initial stage of Quick mode, heating takes
place at full power of the filaments, causing
heating the drying chamber to increased
temperature (maximum temperature value is
higher by 30 % from set drying temperature). Overheating compensates heat
loss during evaporation of large moisture content in the test’s initial stage.
STEP mode
Enables determining up to three steps with
random drying temperature. Step mode is
recommended for drying substances with
moisture content over 15%. Temperature and
heating time in each step have to be adjusted
by tests.
17.2.5. Drying time
Drying time is set by selecting one of available finish mode criteria. This
means that a moisture analyzer must meet pre-set criterion (one of the
requirements: mass over time, time) to automatically finish the drying mode.
Finish of drying process can be triggered by amount of time, independently on
loss in mass. This criterion is used for substances that may decompose during
drying process, and their mass does not reach constant value.
The second criterion is loss in mass (less than 1 mg) in defined amount of
time.
Automatic finish mode (Auto switch off mode)
MA 3Y operator can choose between various types of finish modes:
- Automatic 1 (change 1mg/10s)
- Automatic 2 (change 1mg/25s)
- Automatic 3 (change 1mg/60s)
- Automatic 4 (change 1mg/90s)
- Automatic 5 (change 1mg/120s)
- Time defined (maximum drying time 99 hours 59 minutes)
- Manual (on pressing a function key)
- User defined 1 (set mass change ratio ∆m 0,1-9,9mg and time interval ∆t
max 2,55 sec.
