Actual value at 0 °C (32 °F) is 9.04 Ω per SAMA standard RC21-4-1966.

(2)

Actual value at 0 °C (32 °F) is 100 Ω per DIN standard.

(3)

Values are expressed in 0.1 degree/step or 0.1 Ω/step (applies to all pots, except 150 Ω type). For the 150 Ω pot input type, the values are expressed in 0.01 Ω/step.

(4)

Values are expressed in 1 degree/step or 1 Ω/step (applies to all pot, except 150 Ω type). For the 150 Ω pot input type, the values are expressed in 0.1 Ω/step.
