Description
Used to select the area to store condition settings. There are 10 storage areas labeled from 0 to 9. (See “8-3-
1 Selecting the CONDITIONS (Measuring conditions storage area)”.)
In automatic operation mode, measuring is brought to a end whenever the change in moisture content over
two consecutive 30-second periods falls below the specified conditions for automatic ending. (For further
information, see 8-3-2 “1) Specifying settings for AUTO (Automatic ending) mode”.)
In timed operation mode, measuring is ended when the elapsed time reaches the specified measuring time.
(For further information, see 8-3-2 “2) Specifying settings for TIME (Timed operation) mode”.)
In high-speed drying mode, the sample is dried at a temperature of 180°C until the amount of change in
moisture content over a 30-second interval falls below a specified value and then drying is continued at a
specified drying temperature. (For further information, see 8-3-2 “3) Specifying settings for RAPID (High-
speed drying) mode”.)
In low-speed drying mode, the temperature is raised more gradually than when performing measurements
under normal conditions, taking about 5 minutes from the time when measuring begins until the temperature
reaches the specified drying temperature. (For further information, see 8-3-2 “4) Specifying settings for SLOW
(Low-speed drying) mode”.)
In stepped drying mode it is possible to specify a separate drying temperature and separate measuring time
over up to 5 step intervals. (For further information, see 8-3-2 “5) Specifying settings for STEP (Stepped
drying) mode”.)
Preparatory measuring mode is used for determining the bias (i.e., the difference between the measurement
corresponding to that obtained in automatic operation mode and the predicted measurement value) needed in
order to perform measurements in predictive measuring mode. (For further information, see 8-3-2 “6)
Specifying settings for COMPARE (Preparatory measuring) mode”.)
In predictive measuring mode, the intermediate results of drying are used to predict future changes and to
calculate the result and thereby shorten the measurement time. (For further information, see 8-3-2 “7)
Specifying settings for PREDICT (Predictive measuring) mode”)
This parameter may be used to specify the drying temperature. The temperature may be set
anywhere within a range of from from 30°C to 200°C in 1-degree increments. (30°C to 180°C in 'TT'
mode) (For further information, refer to 8-1 Selecting Temperature Display Mode, 13. Temperature
Calibration and “8-3-3 TEMP (Drying temperature)”.)
This parameter is used to specify a numeric value to be used to correct measurements for bias. A bias
anywhere in the range of from –9.99% to 9.99% may be specified in 0.01% increments. (For further
information, see “8.3.4 Bias”.)

8-3 Descriptions of Individual Measuring Condition Settings
For a detailed description of individual measuring condition settings, see the instructions in subsection 8-2-1
and subsequent subsections.
1
To start specifying measuring condition settings:
Press the
CONDITION
key at a time when the display shows a weight reading.
2
If any password other than the default password of ‘0000’ has been specified, then a ‘PASS’ message will be displayed in
the weight display area. When this message is displayed, follow the instructions in “9.2.7 Specifying a password”, to enter
the password. If the password entered is incorrect, the display will return to the weight display.
3
Selecting individual measuring conditions:
First a ‘CONDITIONS’ message will flash on the display. Pressing the
SELECT
key at this time causes the flashing item to
change in sequence from MODE A TEMP A BIAS A CONDITIONS and back to MODE each time the key is pressed.
When the item you wish to specify is flashing, press the
ENTER
key. Specify the settings for that item.
4
To finish specifying measuring condition settings:
Pressing the
CONDITION
key when any settings item is flashing causes the settings specified to take effect and causes the
display to return to the normal weight display.
