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 Safety Suite Device Configurator (SSDC)
software and a PC, as well as a higher concentration of calibration gas. Follow the instructions
in the next section.
Note: Once the third calibration is set, you do not need to use SSDC to allow future 3-point
calibrations. Also, you can only disable 3-point calibration capability by using SSDC 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.
Note: If a bump test is available, it appears after the last calibration in the menu. See "Two-
Point Calibration," page 42, for details. Also, refer to page 50 for details on how to perform a
bump test.
Note: Dashed line indicates automatic progression.
