Entering the Current
Multiplier
2-26
When the oxygen cell is used in a background gas other than nitrogen,
users must enter the gas's current multiplier, listed in Table 2-7. The
Series 1 will apply the appropriate correction to the oxygen signal.
The original calibration values for nitrogen are programmed into the
"Oxygen Probe Calibration" section. However, the meter uses the
current multiplier to determine the correct oxygen concentration.
To change the Current Multiplier:
Note: The default setting for the Current Multiplier is 1.00.
1. Select a Current Multiplier from Table 2-8 on the next page.
2. From Main Menu, enter the System Calibration Menu by pressing
the following menu keys: SETTINGS, SYSTEM, CALIB.
3. At the System Calibration Menu, press the PROBE menu key until
the Oxygen Probe Calibration screen appears.
4. Use the CHANNEL menu key to cycle to the desired channel. The
channel number is indicated in the top right-hand-corner of the
screen. The screen will only display installed channels.
5. Use the arrow keys to move the pointer to the O2 Current
Multiplier line and press YES.
6. Enter the new value and press YES.
To exit, press the DONE menu key until Main Menu appears on the
message line.
