4.3.6 Version Screen
Move the < > arrow key to More and press Enter . With Version
blinking, press Enter . The screen displays the manufacturer, model, and
software version information.
4.4 The Span Functions
The analyzer is calibrated using span gas.
NOTE: Zero is not necessary for Percent (%) level measurements.
Additional information on Zero functions is provided in the
Appendix A-5 of this manual.
Although the instrument can be spanned using air, a span gas with a
known oxygen concentration in the range of 70–90% of full scale of the
range of interest is recommended. Since the oxygen concentration in air is
20.9 %, the cell can take longer to recover if the instrument is used for very
low levels, such as 1% full scale oxygen analysis, immediately following
calibration in air.
Connect the calibration gases to the analyzer according to the instruc-
tions given in Section 3.4.1, Gas Connections, observing all the prescribed
precautions.
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 sections 4.3.3.2 or 4.3.3.3 to enter your password. Once you have gained
clearance to proceed, you can enter the
Zero
or
Span function.
4.4.1. Cell Failure
When the sensor in the 3010PAC begins to fail, the analyzer will
usually require more and more frequent calibration. If the 3010PAC analysis
readings drift downward uncharacteristically, try recalibration. If recalibra-
tion raises the readings temporarily, the cell may be failing.
You can check the output of the cell itself by going to the System
function, selecting More, and pressing Enter . The cell output reading will be
on the second line of the display.
