THIS IS A FIELD CHECK OF THE FUNCTIONALITY OF THE INSTRUMENT.
THIS TEST DOES NOT CALIBRATE THE INSTRUMENT.
The Functional Test Module is beneficial:
• In applications where frequent verification of functionality is required,
• 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 this H
concentration. The H
S flows over the gold film sensor of the Jerome
2
measures the amount of exposure to the gas. The flow rate and temperature of this release are
factory set to provide a concentration of approximately 250 ppb (0.250 ppm) ±20% when using
FTM Z2600 0918 or approximately 30 ppb ± 20% when using the Low-Level FTM (Z2600 0930).
The user then compares the reading on the Jerome
S level shown on the analyzer's display falls within the expected range for
the module. If the H

the FTM being used, the instrument is functioning properly. If the level is not in the expected
range, it should be returned to the factory for NIST-traceable calibration.
See page 30 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 AMETEK BROOKFIELD P/N 700-0095 for complete operation and warranty
information.
