If you are using password protection, you will need to enter your
password to gain access to either of these functions. Follow the
instructions in section 4.3.3 to enter your password. Once you have gained
clearance to proceed, you can enter the
Zero or Span function.
The procedures that follow can be used for either the zero or span
functions. Only the span function is described.
NOTE: Make sure you choose the right function for the calibration gas
used, i.e. span gas and span function NOT span gas and zero
function!
4.4.1 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 manual mode, where the operator
determines when the span concentration reading is acceptable and then
manually exits the function.
4.4.1.1 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.
Span: Settling: AUTO

Press Enter to move to the next screen.
Span Val: 100.00
Span Mod #
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, press
Enter to begin the Span calibration.
