4.4.1.2 M ANUAL M ODE Z EROING
Press Zero to enter the Zero function. The screen that appears
allows you to select between automatic and manual zero calibration. Use
the ▲/▼ keys to toggle between AUTO and MAN zero settling. Stop
when MAN appears, blinking, on the display.

To Begin
Press Enter to begin the zero calibration.
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.
4.4.2.1 A UTO M ODE S PANNING
Press Span to enter the span function. The screen that appears
allows you to select whether the span calibration is to be performed
automatically or manually. Use the ▲/▼ arrow keys to toggle between
AUTO and MAN span settling. Stop when AUTO appears, blinking, on
the display.
