Appendix B Data Formats and I/O Ranges B-7
B.1.4 Ohms
To indicate ohms, set bits 0 and 1 of the data format/checksum/integration
time parameter to 11; this data format is only valid for ADAM-4013 analog
input modules.
The ohms format allows you to read the value of the RTD resistance in
ohms. It consists of a “+” or “-” sign followed by five decimal digits and a
decimal point. The resolution (position of the decimal point) of Platinum-
Nickel RTDs is 10 m Ω. (two decimal places).
For example, for a 100 Ω. platinum RTD specified for -100
o
C to +100

+100
o
C corresponds to +138.50 Ω. and -100
o
C corresponds to +060.60 Ω.
