Cal/Verify Data
This menu option allows you to view the results of the latest calibration
or verification. This includes the following:
•
O
2
span calibration gas value vs. O
2
span calibration gas reading
•
Zero calibration gas value vs. zero calibration gas reading
•
Span calibration gas drift
•
Zero calibration gas drift
T he terms Span Gas and Zero Gas used in this section refers to the
calibration gas values you enter using the Cal Gas Values menu option.
These values are fixed. Span Value or Zero Value is the value the system
reads from the cal gas. The term Span Drift or Zero Drift is the differ-
ence between the entered calibration gas value and the calibration gas
values read by the system.
Both the latest calibration and verification data will be stored in
memory.
1. Select Cal/Verify Data from the Calibrate key menu.
2. Select Calibration Data or Verify Dat a, depending on whether you
want to see the latest calibration or verification results.
The display then shows the span gas calibration data:
Span Value: xx % O2
Span Gas: xx % O2
Span Drift: xx %O2
Note that the term span value on the display is the value the system read
during the calibrate/verify operation, and the term span gas is the set-
point value entered using the Cal Gas Values option from the Calibrate
key menu.
3. Press the Enter key to then view the zero gas values.
