(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 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 150Ω resistance input type, the

values are in 0.1Ω/step.

(5) This bit is ignored when a resistance device is selected.

(6) Applies to proportional counts data format selected using bits 4 and 5.

TIP

Ensure that unused bit 15 is always set to zero.
