3.5.2. INITIAL CALIBRATION
To perform the calibration you must have sources for zero air and span gas
available for input into the SAMPLE port on the back of the analyzer. See
Section 0 for instructions for connecting these gas sources.
The initial calibration should be carried out using the same reporting range set up
as used during the analyzer’s factory calibration. This will allow you to compare
your calibration results to the factory calibration as listed on the Final Test and
Validation Data Sheet.
If both available DAS parameters for a specific gas type are being reported via
the instrument’s analog outputs e.g. CONC1 and CONC2 when the DUAL
range mode is activated, separate calibrations should be carried out for each
parameter.
 Use the RNG1 button when calibrating for CONC1 (equivalent to LOW
RANGE).
 Use the RNG2 button when calibrating for CONC2 (equivalent to HIGH
RANGE).
The calibration procedures assume:
 that the zero point and span gases have been adjusted for known interferents
(Section 3.3.2.4)
 that the Calibration gas will be supplied through the SAMPLE port
 that the pneumatic setup matches that described in Section 0.
Perform the following outline of procedures for each sensor:
1. Verify the Reporting Range settings as presented in Section 5.4.3. We
recommend that you perform this initial checkout using the following reporting
range settings:
 Mode Setting: SNGL
 Analog Output Reporting Range: 16% for CO2 and 20.95% for O2
2. If the Dilution Ratio Option is enabled on your T803, perform the Dilution
Ratio set up as presented in Section 5.4.4
3. Set the expected Span Gas Concentration for CO2 and for O2, as presented
in Section 9.2.3.1. This should be 80% of concentration range for which the
analyzer’s analog output range is set.
4. Perform the Zero/Span point calibration presented in Section 9.2.3.2
The analyzer is now ready for operation.
Note Once you have completed the above set-up procedures, please fill out the
Quality Questionnaire that was shipped with your unit and return it to
Teledyne API. This information is vital to our efforts in continuously
improving our service and our products. THANK YOU.
