Gas Calibration Menu
Each of the sensor technologies supported by the transmitter uses
unique calibration procedures. The description provided illustrates the
transmitter interface with the sensor. The description does not replace
the procedures found in each sensor's operating manual.
The Gas Calibration menu is used for Zero and Span calibration as
well as functional testing (bump testing). The Gas Calibration menu is
accessed from the Main Menu.

WARNING
!
Warning: Do not use the transmitter in oxygen-enriched atmospheres. Concentrations displayed will
be adversely affected by oxygen depletion.
Warning: Take appropriate precautions when using toxic, flammable, or pressurized cylinders.
CAUTION
!
Caution: The calibration procedure must be performed only by qualified personnel.
The default calibration values for the "Calibration Required" diagnostic
vary based on sensor type. This value can be reprogrammed in
accordance with site requirements to ensure the highest level of safety.
Before commissioning, verify the correct operation of each sensor
by calibration with a certified test gas of known concentration. See
Specifications
CAUTION
!
Caution: Recalibrate if the temperature of local environment has varied by more than ±15°C from the
temperature of calibration.
WARNING
!
Warning: Honeywell recommends periodic bump tests (every 30 days or in accordance with
customer site procedures) to the sensor to insure proper operation and compliance with the functional
