Number of Drying Programs
MA45: 3 programs
Programs are listed according to
program number.
Heating Programs
To perform a moisture analysis of a
substance, you can choose between two
heating programs:
– Standard drying
– MA30 mode
Standard drying:
With the standard program, you need to
enter the final temperature.
If you enter a target temperature of
over 200°C, the moisture analyzer heats
to the target and then adjusts to 200°C
in 5 phases, from the 10th to the 30th
minute.
MA30 Mode:
The moisture analyzer heats as in the
standard mode, but converts to values
corresponding to those in the MA30
(old adjustment disk; 20...200°C –>
20...160°C). This mode is active only
for moisture analysis (before, during
and after drying), but not during heat
adjustment or heating tests.

Standby Temperature
– Temperature set to defined value when
the sample chamber is closed
Initial Weight
You can select a weight to be used as a
guide for applying a sample to the ana-
lyzer. This value is stored as a target
weight and is not used as a start condi-
tion for the drying program. Tolerance
limits of
±
20% are displayed.
Start of Analysis
– With stability after the
u
key
is pressed:
When
START
is shown in the Function
line and you press
u
to confirm, the
initial weight is stored at stability
regardless of whether the cover is open
or closed.
– Without stability after the cover
is closed:
A symbol shown in the graphic symbol
display prompts you to close the cover
once the initial weight condition is met.
The initial weight is stored without
stability as soon as the sample chamber
is closed.
The analysis starts as soon as you
close the cover and a 2-second delay
has elapsed.
End of Analysis with Shutoff
Parameters
– fully automatic mode
– semi-automatic (absolute)
– timer-mode
Fully Automatic Mode:
The analysis ends as soon as the weight
loss per 24 s is below an automatically
detected threshold.
Semi-automatic, absolute:
The analysis ends as soon as the weight
loss per 24 s is lower than a user-
defined threshold (set in milligrams).
Timer Mode:
The analysis ends as soon as the
specified time has elapsed.
Display Mode
The following units can be selected for
displaying analysis results:
– Moisture
%L
– Dry weight
%R
– Ratio
%LR
– Residual weight
g
– Residual weight
g/kg
Print Intermediate Results
Intermediate results can be printed
either at user-definable time intervals
or by pressing the
r
key.
Factory Settings
The drying programs can be reset to the
factory settings.
