(2) Setting methods
When “Up scale”, “Down scale” or “Given value” is selected in Conversion setting for
disconnection detection (Un\G164, Un\G165), the value to be stored into CH
Measured temperature value (Un\G11 to Un\G18) in disconnection detection can be
specified.
(a) Up scale and down scale
When “Up scale” (0H) or “Down scale” (1H) is selected, an up scale value or down
scale value of thermocouple-type to be used is stored into the CH Measured
temperature value (Un\G11 to Un\G18).
(b) Given value
When “Given value” (2H) is selected, set a value in the CH Conversion setting
value for disconnection detection (Un\G166 to Un\G173) in units of 0.1 .
The value set in the buffer memory above is stored into the CH Measured
temperature value (Un\G11 to Un\G18) when disconnection is detected.
