7.2.38 BFM #79: Temperature rise completion range setting
In BFM #79, set the temperature rise completion range. This setting is applied to both CH1
and CH2.
Set the temperature range in which the temperature rise completion range is judged based on
the temperature set value.
The actual temperature rise completion range is judged within the range above and below the
temperature set value, so the range width is twice.
7.2.39 BFM #80: Temperature rise completion soak time
In BFM #80, set the temperature rise completion soak time. This setting is applied to both CH1
and CH2.
The temperature rise completion soak time is the period of time after the measured value
reaches the temperature rise completion range until the temperature rise completion flag turns
on.
In order to cope with a case in which the measured value has reached the temperature rise
completion range but is not stable yet, by setting the soak time, the wait time can be set for
judgement on temperature rise completion.
