5) Specifying settings for STEP (Stepped drying) mode
In stepped drying mode it is possible to specify separate measuring conditions for up to a maximum of 5
steps. Specifying a separate drying temperature and separate measuring time for each step makes it
possible to specify finer-grained sets of measuring conditions.
In Step 1, timed halting mode must be specified as the mode used to define halting conditions. In Step 2 and
subsequent steps, it is possible to select between either automatic halting mode or timed halting mode.
* If automatic halting mode is selected as the mode to be used in Step 2 or later, that step becomes the final step.
Similarly, when timed halting mode is selected and a value of ‘0’ is specified as the measuring time, the previous
step becomes the final step.
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

highlight to shift to the specification of the measuring time for Step
1, and for the measuring time to begin to flash.
Press the key or key to select the desired measuring
time. The time may be set to a length of anywhere from 1 to 240
minutes in 1 minute increments. Note that here a time of 20
minutes has been specified.
When the desired measuring time flashes, press the key.
The measuring time will change from a flashing to a constantly lit
display the highlight will shift to the specification of the drying
temperature, and the drying temperature will begin to flash.
Press the key or key to select the desired drying
temperature. The temperature may be set to a temperature of
anywhere from 30 to 180
°
C in 1 degree increments. Note that
here a temperature of 105
°
C has been specified.
When the desired drying temperature flashes, press the
key. The step displayed will change from ‘STP 1’ to ‘STP 2’ and
the units area for timed halting mode (‘min’) or automatic halting
mode (‘%’) will begin to flash.
