(3) The performance specifications that are given for the G6F
do not apply if any fluids other than the specified applicable
fluid are used.
(4) Foreign matter in the tubes that are connected to the Sensor
may damage the Sensor. Prevent any foreign matter from
entering the tubes after the Sensor is removed from its
packaging.
(5) Attach the tubes so that fluid flows only in the direction designated by the arrows on the Sensor. Correct measurements
cannot be obtained if the fluid flows in the wrong direction.

(1) Make sure that the tube connections to the barb joints are
airtight. Any leaks from these joints will result in incorrect
measurements.
