APPENDIX B - J605 FUNCTIONAL TEST MODULE
The Jerome
®
Hydrogen Sulfide Functional Test Module (AZI P/N: Z2600 0918 or Z2600 0930)
provides a fast and easy method of verifying that Jerome
®
J605 Hydrogen Sulfide Analyzers are
functioning correctly.
The Functional Test Module is beneficial:
In applications where frequent verification of functionality is required, such as ISO 9000
documentation,
To verify proper instrument operation when unexpected readings are obtained in normal
sampling,
As part of a weekly maintenance routine, and
To determine if analyzer calibration is needed.
Simple Operation
The Functional Test Module includes a permeation tube containing hydrogen sulfide. When
activated, the test module releases H
2
S from the permeation tube at a specific, known
concentration, which is then sampled by the J605. The H
2
S flows over the gold film sensor of the
Jerome
®
analyzer, which then measures the concentration of the gas. The flow rate and
temperature of the H
2
S release are factory set to provide a concentration of approximately
0.250 ppm (250 ppb) ± 20% (Z2600 0918) or 0.030 ppm (30 ppb) ± 20% (Z2600 0930). The user
then compares the reading on the Jerome
®
analyzer with the known concentration from the
module. If the H
2
S level shown on the analyzer’s display falls within the expected range, the
instrument is functioning properly. If the level is not in the expected range, the instrument should
be returned to the factory for NIST-traceable calibration. Complete usage details are provided in
the manual included with the FTM.
See page 40 for a list of the components that make up the FTM and its accessory kit.
The FTM, with the exception of the permeation tube, carries a limited one-year warranty to be
free from defects or workmanship. The permeation tube is warranted for 90 days. Refer to the
FTM Operation Manual (AZI P/N: 700-0095) for complete operation and warranty information.
