Actual value at 0°C is 9.042
Ω
per SAMA standard RC21-4-1966.
(2)
Actual value at 0°C is 100
Ω
per DIN standard.
(3)
Values are in 0.1 degree/step or 0.1
Ω
/step for all resistance input types, except 150
Ω
. For the 150
Ω
resistance 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 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.
