The module scan for analog signals can consist of up to four acquisition cycles. Each cycle includes a specific set of channels. Total Scan Time depends on the number of acquisition cycles

in the scan, the configured filter option, and whether channels are analog or HART.

Calibrated Accuracy In the presence of severe RF interference

(IC 801-3, 10V/M),

accuracy may be degraded by ±1.5% of range.

From 13°C – 33°C:
