Verify User Units setting and Titration Efficiency (TE) value:
•
User Units (unit of Measure): PPB
•
TE is 96% or greater (check Titrate Eff in Dashboard; if less than .96, adjust in
Setup>Vars – see Section 4.4. No adjustment needed if
≥
.96).
Then perform the calibration:
•
Perform a Zero calibration using zero air on both NO
2
& NOx channels.
•
Perform a Span calibration on both the NO
2
& NOx channels using a known
concentration of NO
2
span gas.
•
Perform the Titration Efficiency (TE) check using a known concentration of NO
span gas. No adjustment of TE value is required if the efficiency is good.
Note
The span gas concentration should be 80% of range of
concentration values likely to be encountered in your
application.
To calibrate or to perform a calibration check for basic configuration instruments, see
Section 4.2.1.
To calibrate or to perform a calibration check for instruments with valve options, see
Section 4.2.2.
To perform a calibration check for instruments with the internal span gas generator, see
Section 4.3.
CALIBRATION AND CHECK PROCEDURES FOR BASIC
CONFIGURATION
Although this section uses the Calibration menu for both calibration check and actual
calibration, a check does not require the Calibration menu. Instead, while in Home page,
simply flow the zero air or the NO
2
span gas through the Sample port, and check the
reading after the Stability falls below 1.0 PPB (either in the gas graph or in the
Dashboard).
Otherwise, follow the steps presented in Sections 4.2.1.1 and 4.2.1.2.
