−103−
measurement mode. They need not be set for the 2-
channel mode.
The period can be varied in a range between 0.5 s and
10 s. When setting the bits, use a value ten times the
desired period.
(Example) 2 s → 20 (14h)
The valid data range is between 5 and 100 (64h). Any
value out of this range is regarded as being 40 (28h),
that is, 4 s. If nothing is specified, a period of 4 s is
again assumed.

DO18 : Sensor type
This bit is set according to the type of the temperature
sensor being used.

DO19 : Reserved for future use
This bit must always be set to "0".
DO24 : Number of channels
This bit is used to specify the number of channels to be
measured.
0 :2 channels
1 :4 channels (if 1 is selected, DO25 must also be
used.)
DO25 : 4-channel mode specification
This bit is used to select the 4-channel mode to be used.
0 :Automatic measurement (the period is specified
using DO00 to DO15.)
1 :Manual measurement (a request is issued using
DO22 and DO26 at every data read.)
