13.5. Selecting 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 (requirement) (mass over
time, time) to automatically finish the drying mode.
Finish of drying process can occur on elapsing defined 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)
The moisture analyzer MAX series enables selecting 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.
- User defined 2 (set moisture content change ratio % M ove r tim e
- Test (enables adjusting finish mode parameters to a tested sample)
Automatic finish mode – user defined criterion (mass/time)
The operator determines the limit value for loss of mass and time in which the
loss of mass must not exceed a pre-set value. As the moisture analyzer
reaches the set criterion it automatically finishes the measurement (drying
process).
Manual finish mode
An operator ends drying process manually by pressing START/STOP button on
moisture analyzer’s display.
Time defined finish mode
Drying process finish takes place on elapsing a set amount of time,
independently on measurement result.
