Section 6 - Operating your Moisture Analyzer
Auto switch-off
The switch-off criterion is based on a
weight loss per unit of time
. As soon as the mean weight loss is less
than a preset value during a specified time, the instrument considers drying as complete and automatically
discontinues the measurement process. During drying, the display indicates the elapsed time of the drying
process; the switch-off criterion is inactive during the first 30 seconds.
The automatic switch-off criterion is divided into three selectable levels:
A30
: Less than 1mg loss in 30 seconds, used for samples which dry very quickly (surface moisture) or
for (relatively inaccurate) fast measurements to determine a trend.
A60
: Less than 1mg loss in 60 seconds, used for most types of samples.
A90
: Less than 1mg loss in 90 seconds, used for slow drying substances (trapped moisture, skin
formation).
Select the criterion for your measurements.
TEST PARAMETERS
SWITCH OFF
Using the arrow buttons, scroll to SWITCH OFF and press the
Enter
button.
Using the arrow buttons, scroll to either A30 <1MG IN 30 SEC, A60 <1MG
IN 60 SEC or A90 < 1MG IN 90 SEC and press the
Enter
button.
Auto free switch-off
Auto free switch-off criterion is based on a user defined mean weight loss per unit of time. If none of the three
switch-off criteria Weight loss per unit of time is suitable for your application, the Moisture Analyzer allows you
to define a free switch-off criterion. The free switch-off criterion is also based on the principle of the mean weight
loss per unit of time. As soon as this drops below the preset value, the measurement is automatically ended.
