4.4.2 Span Cal
The
Span
button on the front panel is used to span calibrate the ana-
lyzer. 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 cali-
bration can also be performed in manual mode, where the operator deter-
mines when the span concentration reading is acceptable and manually exits
the function.
4.4.2.1 Auto Mode Spanning
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.

Calib. Holding time
Cal hold: 5 min
This menue allows the operator to set the time the analyzer should be
held in the span mode, after the readings of the analyzer settle. Five minutes
is the default, but it could be adjusted anywhere from 1 to 60 minutes by
using the UP or DOWN keys.

Use the
∆∇
arrow keys to enter the oxygen-concentration mode. Use
the < > arrow keys to blink the digit you are going to modify. Use the
∆∆∆∆∆∇
arrow keys again to change the value of the selected digit. When you have
finished typing in the concentration of the span gas you are using
(209000.00 if you are using air), press
Enter to begin the Span calibration.

The beginning span value is shown in the upper left corner of the
display. As the span reading settles, the screen displays and updates informa-
