16900 Refrigerant Identifier 11
Operating Procedure
4. The instrument draws in ambient air through the air intake port
for approximately one minute. Ambient air is used to calibrate the
detection devices and purges the instrument plumbing of residue
refrigerant vapors.
NOTE: For a correct calibration, the surrounding ambient air must
be clear of refrigerant vapors, hydrocarbons, and oxygen-depleting
compounds such as carbon dioxide or carbon monoxide.
5. When prompted by the instrument, connect the free end of the
sample hose to the vehicle air conditioning system or refrigerant
storage cylinder port. Press the A pushbutton. Sample gas
immediately begins to flow into the instrument. The instrument
requires approximately one minute to complete the sample gas
analysis.
6. When the analysis is complete, immediately disconnect the sample
hose from the refrigerant source.
NOTE: The instrument does not contain automatic shut-off, and
refrigerant vapors continue to flow out of the source as long as
the hose is connected. To conserve refrigerant stores and prevent
excess refrigerant venting, do NOT leave the instrument unattended
during analysis cycles. Disconnect the sample hose from the source
immediately after being prompted by the instrument.
