During calibration, if the SCOTT INSTRUMENTS MINI-SA detects a sensor
with insufficient output to be calibrated, the following screen will appear:
<gas> SENSOR

If one of these screens appears, verify that the proper gas is flowing to the
instrument and all fittings are properly connected. Then press “RECAL” to
attempt the calibration again. If calibration is not successful, press “TURN
OFF” and service the instrument as needed.
On subsequent power on, the INITIALIZING line on the first screen
displayed (SCOTT INSTRUMENTS MINI-SA...) will be replaced with
CALIBRATION REQUIRED, until the instrument is successfully
recalibrated. This may require replacing the sensor.
