After the zero calibration completes its cycle, the information is
stored in the microprocessor, and the instrument automatically returns to
the
Analyze
mode.
4.4.2 Span Cal
The
Span
button on the front panel is used to span calibrate the
analyzer. Span calibration can be performed using the
automatic
mode,
where an internal algorithm compares consecutive readings from the
sensor to determine when the output matches the span gas concentration.
Span calibration can also be performed in
manual
mode, where the
operator determines when the span concentration reading is acceptable
and manually exits the function.
