Analog signal on alarm
The transmitter automatically and continuously performs self-diagnostic routines. If a
failure or a measurement error is detected, the analog signal will be driven offscale to alert
the user. High or low failure mode is user-configurable.

Analog saturation levels
The transmitter will continue to set a current that corresponds to the measurement until
reaching the associated saturation limit (and then freeze).
