Open Circuit
➀
00 = zero 01 = upscale 10 = downscale 11 = illegal
Bits 8-10 Filter Frequency
000 = no filter
001 = 75 Hz
010 = 50 Hz
011 = 20 Hz
100 = 10 Hz
101 = 5 Hz
110 = 2 Hz
111 = 1 Hz
Bit 11 Channel Enable 0 = channel disabled 1 = channel enabled
Bits 12-15 Not Used 0000 = always make this setting
➀
The open circuit option is only valid for the 4-20 mA data format.
