7.4 Range Reference Table
The range reference table is given below.
(1) Compare the Factory default offset value with the reference value
1DDB
H.
(2) Compare the Factory default gain value with the reference value 58A7
H.
(3) Compare the User range settings offset value with the value obtained
from the following expression.
(4) Compare the User range settings gain value with the value obtained
from the following expression.
(5) Compare the User range settings resistance offset value with a value
obtained by (a) and (b) below.
(a) Obtain a reference resistance value that corresponds to the offset setting
temperature set by the user from the chart of RTD's reference resistance value
(RTDs compliant with JIS C 1604-1997 or IEC 751 1983, JIS C 1604-1981, or DIN
43760 1987).
(b) Multiply the reference resistance value obtained in the step (a) by 1000.
