Honeywell SEARCHLINE EXCEL PLUS Guia De Inicio Rapido página 3

The gassing test cell allows the Searchline Excel™ Plus and
Searchline Excel™ Edge calibration to be checked using
a user-specified gas concentration, as an alternative to the stand-
ard functional test filters.
CAUTION
Prerequisite for calibration check using the gassing test cell is
installation of the Honeywell Fixed Platform App to a suitable
handheld device.
The test gas must be the same as the gas calibration of
the Searchline Excel Plus or Searchline Excel Edge units and ide-
ally the concentration should be between 2 and 5 LEL.m, never
below 1 LEL.m.
Note
For Universal Calibration units any of Methane, Ethane, Propane,
Butane, Ethylene can be used. Natural gas mixes can also be tested.
Note
Cross-calibration is not recommended. Typical values for cross-
sensitivity are not sufficiently precise to enable valid calibration
checks using the gassing test cell. Response tests can easily be
performed with the functional test filters.
Refer to the Technical Manual for more information.
WARNING
Take necessary precautions to ensure safety when dealing
with high concentration gasses.
