*Critical alarm conditions will render the O2 measurement as unusable, and any of these events will cause the 4-20 mA signal to go to a user-selectable limit of 3.5 mA or 21.6 mA (position 3 of SW2). Factory default value is 3.5 mA. Alarms which are not “self-clearing” will require recycling of power to the electronics.

**The CALIBRATION RECOMMENDED alarm flashes the Calibration Recommended alarm LED on the opera- tor’s keypad.
