Plasma Gas Analyzer
34 02001001A_9
The display shows the actual ppm of nitrogen value and the actual flow in cc. If the unit is started
up for the first time or you replace the calibration gas with a new value, the ppm display has no
meaning. This can be zero or off scale.
In order to calibrate the unit properly, all lines and regulators on the calibration cylinders must
be completely purged. Allow the zero gas to flow into the analyzer. After 10 minutes of the zero
gas flowing into the analyzer, select
"F1" on the keypad. You will be asked for a confirmation to
re-zero, select "YES" , at this moment this message will be replaced by "PLEASE WAIT" ,
indicating the sampling of the analogue input. This message is displayed for 5 seconds.
NOTE: an indicator is displayed on the right of the confirmation message informing the user if
the re-span or the re-zero has not been performed yet.
After this delay, the "ZERO DONE" message is displayed. Now, allow the span gas to flow into
the analyzer for 10 minutes or until the displayed measure value is very stable. Select "F2" on
the keypad. Again, you will be asked for a re-span confirmation, select "YES" , at this moment,
again, this message will be replaced by "PLEASE WAIT" on the display for a certain amount of
time. When this step is done, the "SPAN DONE" message is displayed; the span gas value is
shown on the left corner of the display. Recheck zero and, if necessary, calibrate a second time.
When the calibration procedure is finished, go back to the CALIBRATION MAIN MENU by
pressing "F4" on the keypad. From the CALIBRATION MAIN MENU , select "F4" again to go
back to the MAIN MENU ( TOP LEVEL MENU ).
