bration has been completed and it is time to terminate the
calibration procedure
7. When either a minimum or a full calibration has been com-
pleted the regulator valve is closed on the gas bottle and the
calibration cap should be removed. Pay close attention to
the indicator light when removing the calibration cap since
the result of the calibration is immediately shown on the
indicator light when the magnetic switch is turned off. The
indicator light shows 15 fast flashes (5 per second) of either
green light or red light. If the flashes are green, the cali-
bration has been completed and stored successfully. It the
flashes are red, the calibration has failed during the process
and the calibration procedure must be restarted.
!
CAUTION
If your sensor is installed using a flow cell, you must inspect
the O-ring at the tip of the sensor when it is removed from
the flow cell. If O-ring is worn or damaged it must be replaced
by a new. Replacement O-rings and O-ring grease have been
delivered together with the flow cell.
IMPORTANT NOTE
The fifteen short green flashes at the final stage of calibration
is the only indication visible to the operator of a successful
calibration. However, if in doubt, we recommend that the
calibration validity is checked subsequent to calibration by
exposing the SulfiLogger™ sensor to the calibration gas and
checking the reading at the SCADA system or through the
SulfiLogger App (The SulfiLogger™ sensor only). Please make
sure to turn the calibration cap so that the arrow is NOT
