APPENDIX A - 431-X FUNCTIONAL TEST KIT
If your application requires frequent verification of instrument functionality, this test will benefit
you. If the test results fall within the expected range, you may assume the instrument is
functioning properly.
THIS IS A FIELD CHECK OF THE FUNCTIONALITY OF THE INSTRUMENT.
THIS TEST DOES NOT CALIBRATE THE INSTRUMENT.
NOTE: Perform the functional test ONLY after a sensor regeneration.
The 431-X Functional Test Kit (FTK) contains all accessories necessary to perform the
functional test. See the complete list on page 30 and verify that all the parts to the kit are
present.
CAUTION
:
The vial and thermometer contain liquid mercury and are possible sources of mercury
contamination. Follow the instructions for handling or transferring the mercury into the
Functional Test Kit (FTK) Mercury Vessel carefully.
For safety information, see the supplier’s Safety Data Sheets (SDS) or call AZI Customer
Service at 1-800-528-7411 or 1-602-470-1414 for assistance in obtaining the SDS.
Preparation
•
Carefully unpack and inspect the parts of the kit.
•
ENSURE that the mercury shipping container and mercury filled thermometer are not
broken.
•
In a ventilated area, preferably under a fume hood, remove the mercury vial from its
shipping container.
•
Place the FTK mercury vessel and the mercury vial close to each other and open the
mercury vial.
CAUTION:
The edge between the plastic case and the glass inner vessel of the functional test kit vessel
are not sealed tight enough to prevent mercury from entering the area between the inner
and outer vessels. ENSURE the mercury, transferred in the next step, does not contact the
seal where the glass and plastic portions join.
