The given span of the specified range is used to determine the RTD input ranges for twos complement hexadecimal values. For an example, if the nickel RTD is specified for the range -80oC to +100o C, the corresponding values in hexadecimal notation would be 8000h to 7FFFh.

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 module.

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, a 100 Ω platinum RTD specified for -100oC to +100o C has +100o C corresponding to +138.50 Ω and -100oC corresponding to +060.60 Ω.
