8.8 Calibration reports
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.
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
Data available
on page 77 for examples.
Each calibration record will contain parameters useful for traceability. For instance, it will contain:
• 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.)
