Alarm Mode

The Alarm mode specifies the analog output state when there is a failure or a measurement error:

High: the output current is set to the High Alarm Limit.

Low: the output current is set to the Low Alarm Limit.

Freeze Current: the output current is set to the last valid value at the time when the error occurs.

Default settings for alarm mode:

•Measurement errors: Output current=High.

•Measured value out of range: transmitter enters saturation mode (if Limit Alarm is disabled).
