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