(1)
Actual value at 0 °C (32 °F) is 9.042 Ω per SAMA standard RC21-4-1966.
(2)
Actual value at 0 °C (32 °F) is 100 Ω per DIN standard.
(3)
Values are in 0.1 degrees/step or 0.1 Ω/step for all resistance input types, except 150 Ω. For the 150 Ω, resistance input type, the values are in 0.01 Ω/step.
(4)
Values are in 1 degree /step or 1 Ω/step for all resistance input types, except 150 Ω. For the 150 Ω, resistance input type, the values are in 0.1 Ω/step.
(5)
This bit is cleared (0) when a resistance device, such as a potentiometer, is selected.
