Bits 9
and 10 Filter Frequency
Select 00 = 10 Hz 01 = 50 Hz 10 = 60 Hz 11 = 250 Hz
Bit 11 Channel Enable 0 = channel disabled 1 = channel enabled
Bit 12 Excitation Current
Select 0 = 0.2 mA 1 = 0.5 mA
Bit 13
and 14 Scaling Select 00 = module defined
scaling (default) 01 = config. words 4 & 5 for
scaling 10 = config. words 6 &
7 for scaling 11 = Not used

Bit 15 Not Used 0 = always make this setting
(1) 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.
