particular sensor is completed, press
the MODE button to confirm the
calibration and then use the
navigation arrows to advance to the

If using a calibration
balloon and the calibration of more
than one sensor is required, deflate
the calibration balloon fully before
filling it with new gas for subsequent
calibrations. Failure to fully deflate
the calibration balloon between
calibrations may lead to inaccurate
and potentially dangerous readings.
