(1) The "temperature-measuring resistance value" input from the platinum
temperature-measuring resistor is converted into a "temperature value" to detect a
temperature.
(2) The value of the measured temperature to the third decimal place is multiplied by
1000 and the result is stored into buffer memory in 32-bit signed binary. (All digits
to the right of the fourth decimal place are rounded down.)
(3) A negative temperature measurement value is displayed as two's complement.
(4) At power-on or reset, all channels are set to 0.

channel.
(2) 0 is set at power-on or reset.
(3) The scaling range that may be set is -2147483648 to 2147483647.
(4) Scaling will not be made if the upper limit value and lower limit value are equal.
(5) The Operation Condition Setting Request (Y9) must be turned on/off to make the
setting valid.
(1) Set the scaling with on each channel.
(2) 0 is set at power-on or reset.
(3) The scaling range that may be set is -32768 to 32767.
(4) Set the upper limit value and lower limit value to 0 when scaling will not be made.
