Description

03

(03)

Powerup bit – this bit is set (1) until configuration data is
received by the module.

04 to 06 (04 to 06) Critical Fault bits – If these bits are anything other than zero,

return the module to the factory for repair.

07 (07)

Unused – set to 0

08

(10)

Calibration Range bit – set to 1 if a reference signal is out of
range during calibration

09

(11)

Calibration Done bit – set to 1 after an initiated calibration
cycle is complete.

10

(12)

Calibration Bad bit – set to 1 if the channel has not had a valid
calibration.

11 to 15 (13 to 17) Unused – set to 0

Fixed Digital Filter – When this bit is set (1), a software digital
filter is enabled. This filter settles to 100% of a Full Scale step
input in 60 scans.

Calibration High/Low bit – This bit is set during gain
calibration; reset during offset calibration.

07

(07)

Calibration clock – this bit must be set to 1 to prepare for a
calibration cycle; then reset to 0 to initiate calibration.

08 to 15 (10 to 17) Calibration mask – The channel, or channels, to be calibrated

will have the correct mask bit set. Bit 8 corresponds to
channel 0, bit 9 to channel 1, and so on.
