5.6 Interference Calibration (TC sensor)
Instructions
For interfering oxygen on measured hydrogen or nitrogen, expose both sensors to
ambient air, or a 100% oxygen source, and press
Start
to initiate the calibration.

5.7 Barometric Pressure Calibration
This calibration is available for TC sensors and is required
when one of the interferences has been enabled (
See
“Interferences Configuration” on page 51 ). The lower part
of the screen displays the actual measurement.
Select from the interfering gas to be calibrated from
those available, or press the
Change configuration
button to reconfigure and go back to the process
described in
“Interferences Configuration” on page 51
⌧
Hold during calibration: Selected by default, this holds
the measurement sequence to avoid storing invalid
values during calibration.
Upper box shows the barometric pressure measured by
the instrument.
Using a precision certified barometer, measure the
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.
Once the calibration is completed a calibration report is
created.
Note:
The barometric sensor has been factory calibrated.
