Teledyne API T801 NDIR CO2 Analyzer Operation Manual Getting Started
53
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 3.3.2.1)
that the calibration gas will
be supplied through the SAMPLE port
that the pneumatic setup matches that described in Section 3.3.2
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 CO
2
2. If the Dilution Ratio Option is enabled on your T801, perform the Dilution
Ratio set up as presented in Section 5.4.4
3. Set the expe
cted Span Gas Concentration for CO
2
as presented in Section
9.2.3.1. This should be 80% of concen
tration 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
