3.4.16 CH measured temperature value (32 bit) (Un\G54 to 61)
(1) The "temperature-measuring resistance value" input from the RTD 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 measured temperature value is displayed as two's complement.
(4) At power-on or reset, all channels are set to 0.
[Example 1] At the measured temperature value of 123.025
.....
123025 is stored.

3.4.17 CH scaling range upper/lower limit values (Un\G62 to 77)
(1) Set the scaling range (0.001 increments) of the measured temperature on each
channel.
(2) 0 is set at power-on or reset.
(3) Allowable scaling range is -2147483648 to 2147483647.
(4) Scaling will not be made if the upper limit value and lower limit value are equal.
(5) The Operating Condition Setting Request (Y9) must be turned on/off to make the
setting valid.
3.4.18 CH scaling width upper/lower limit values (Un\G78 to 85)
(1) Set the scaling with on each channel.
(2) 0 is set at power-on or reset.
(3) Allowable scaling range is -32768 to 32767.
(4) Set the upper and lower limit values to 0 when scaling will not be made.
(5) The Operating Condition Setting Request (Y9) must be turned on/off to make the
setting valid.
