20 Three-Point Calibration
For enhanced accuracy, it is possible to perform a second Span
calibration in addition to the Zero and Span calibrations outlined in
the previous section. Your instrument first must be set to allow this
third calibration. This requires using ProRAE Studio software and a
PC, as well as a higher concentration of calibration gas.
Note:
Once the third calibration is set, you do not need to use
ProRAE Studio to allow future 3-point calibrations. Also, you can
only disable 3-point calibration capability by using ProRAE Studio
again.
Perform the Zero and Span calibrations. After the first Span
calibration (Span 1) is completed, the display a second Span
calibration (Span 2) can be performed. The process is identical to the
first calibration. As in the Span 1 calibration, you may exit and return
to the Zero calibration screen if you choose not to perform this
calibration or to abort it.
