C.4.3

Analog alarm limits

High/low alarm value

The high/low alarm current for the analog output when the device enters the alarm mode.

Related information

Analog signal on alarm

High/low saturation value

The device will continue to set a current that corresponds with the measurement until
reaching the upper/lower limit (and then freeze).
