Ohms
To indicate ohms, set bits 0 and 1 of the data format/checksum/integration time
parameter to 11.
The ohms format allows you to read the value of the RTD resistance in ohms. It con
-
sists of a “+” or “-” sign followed by five decimal digits and a decimal point. The reso
-
lution (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 -100°C to +100°C has +100°C cor
-
responding to +138.50 Ω and -100o C corresponding to +060.60 Ω.
The measurable resistance values are as given below:
