8.7 Barometric pressure calibration

Barometric pressure calibration
Note: The barometric sensor has been factory calibrated but should be periodically verified with a
precision certified barometer. This is only necessary if measuring in gas phase with fraction units (%,
ppm).
Upper box shows the barometric pressure measured by the instrument.
Using a precision certified barometer, measure barometric pressure in the location where the measuring
instrument is used. Compare the values, if values are the same press Cancel, otherwise enter the new
barometric value in the lower box and Validate the new setting.
On completion a calibration report is created.

8.8 Calibration reports

Calibration reports
Once a calibration is completed (for a gas or pressure sensor), the calibration report is updated with the
new details. The calibration report contains data for the last 10 calibrations.
For full details on the data displayed for all the different type of calibration reports, refer to
on page 77
Each calibration record will contain parameters useful for traceability. For instance, it will contain:
•
•
•
•
•
for examples.
the date and time
the calibration mode (zero, 100% humid air, or high level adjustment)
the calibration type (manual or automatic)
the operator name and ID
all the measurements which influence the calibration (temperature, barometric pressure, current,
etc.)
