Cal Mode
Calibration mode allows for sensor
calibration and maintenance by
holding the relays in their normal
state, preventing unwanted alarms. If
the unit is left in Cal Mode, it will stay
active for 48 hours and then return
to normal operating mode. Make
sure the concentration values have
dropped below the warning and alarm
setpoints before exiting. ESC to exit
from Calibration mode and return to
normal operating mode. The analog
outputs are not affected by calibration
mode and are allowed to increase to
full scale.
