WARNING! You must ensure that there is a no flow condition before proceeding. If you

are performing the test in a bottle, be sure to isolate the sensor in a closed container -

any air movement (even from a fan) may result in a false "fail" result.

Once process is stable, press YES (F3) key to begin the Zero CAL-CHECK

This test will take less than 5 minutes. The T=xx is a count down timer indicating how

much time is left to finish the test.

Upon test completion, the final value will be displayed along with the test result. The

test result may be:

• Pass < 0.80

• Warning > 0.80 < 1.0

• Fail > 1.0

If a "Warning" or "Fail" result is displayed, ONICON recommends that the probe be

removed from the pipe, the sensor cleaned, and the test be performed again. If the test

was performed in the pipe the first time, perform the test in a bottle for the re-test.

If a "Warning" or "Fail" result is displayed after performing the test a second time,

please call ONICON Service at 727-447-6140 for assistance.
