9-2-2 Selecting the MODE (Measuring mode)
The ‘MODE’ (measuring mode) setting is used to specify the conditions under which measuring is to be
completed. As shown in the table in subsection “9-1 Types of Settings”, the mode may be set to one of seven
methods.
1) Specifying settings for AUTO (Automatic halting) mode
In automatic mode, measurement is brought to completion when
the amount of change in moisture content over a period of 30
seconds falls to a level below a specified threshold level. The
automatic halting threshold level may be specified in 0.01-percent
increments from 0.01 to 0.1percent.
Specifying a smaller percentage causes measurements to approach a
point of equilibrium, but more time is then required for measurement.
Specifying a higher percentage lessens the amount of time required for
measurement, but measuring is completed while there may still be a wide
variation in measurements. The automatic halting conditions should be
specified in accordance with your objectives and the type of sample being
measured.

Key(s) used Operating instructions
With the display displaying the weight in grams, press the
key.
If a password has been specified, the message ‘PASS’ will be
displayed to indicate that a password should be entered. Follow
the instructions in “10-2-7 Specifying a password” on p. 46 to
enter the password.
The ‘CONDITIONS’ display area will begin to flash. Press the
key until ‘MODE’ begins to flash.
With the ‘MODE’ display area flashing, press the key. This
will cause the highlight to shift to measuring mode selection and
for the currently specified measuring mode to begin flashing.
Press the key until ‘AUT’ begins to flash.
* Since ‘AUT’ will already be flashing at the point, proceed directly
to the next step.
When ‘AUT’ begins to flash, press the key. This will cause
the automatic halting mode settings to become active and for the
automatic halt conditions (i.e., amount of change in moisture
content per 30 seconds) to begin flashing.
Press the key or key to select the automatic halt
conditions. Note that here we specify a setting of 0.1 percent.
When the desired automatic halt conditions setting begins to
flash, press the
key. The automatic halt conditions setting
will change from a flashing to a constantly lit display and ‘MODE’
will begin to flash instead.
If you wish to specify other measuring conditions settings, press
the
key to select the setting to be specified. To exit from
specifying measuring conditions settings, press the key
instead.
