Teledyne 3010PA - Split architecture percent oxygen analyzer - Manual (Page 42)

Oxygen Analyzer Part I: Control Unit
Part I: 4-11
Version Self—Test
Cell Output: ### µA
The “good” reading depends on the class of cell your analyzer is using.
Although the B-1 cell is standard in the 3010PA, check Specific Model
Information in the Front Matter in this manual for the class of cell you
purchased.
Then check Cell Replacement in Part II Analysis Units, chapter 5
Maintenance, and do the prescribed calculations. If a weak cell is indicated,
replace the cell as described there in chapter 5.
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.

Span Val: 20.90
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 (20.90 if
you are using air), press
Enter to begin the Span calibration.
