Output n 00 Data hold When this bit is turned ON, conversion of the temperature input
data is stopped and data is returned to its status just prior to turning the
bit ON. When this bit is turned OFF, the temperature input data is
converted to BCD data in cycles.

specification
code number
These bits specify the temperature specification code number of the
temperature sensing element used in the Unit. A total of 41 code
numbers (thermocouple K (CA) = 11, thermocouple J (IC) = 4, L(Fe-CuNi)
= 4, platinum RTD JPt = 11, platinum RTD Pt= 11 numbers) can be
specified in 2-digit BCD from 00 through 25. (Refer to pages 3 and 16 for
details.) The temperature specification code number becomes valid after
the temperature specification setting flag (word n bit 15) is turned ON.
14 --- Not used. Always turned OFF.
15 Temperature

When this bit is turned ON, the temperature specification code number
specified for word n bits 08 through 13 becomes valid. Be sure to confirm
beforehand that the temperature specification switch (pin 3) on the back
panel has been set to the ON position and that the setting standby flag
(word n+5 bit 06) has also been turned ON. Otherwise the code number
is invalid.
