Figure 3 shows the control buttons on the front of the gas analyzer:
1. The "O2/NOx" button is used on 5-Gas analyzers only. The O2/NOx button switches
the display from reading Oxygen to reading NOx. The default following warm-up or
restart is O2. Switching from O2 to NOx, press the O2/NOx button, hold down until the
decimal point disappears and then release the button. The analyzer will now display
NOx.
2. The "Z" button has several functions.
a. Zeroing the gas analyzer as needed during use.
b. Restarting the pump following automatic shutdown.
c. Used along with the "C" button to begin calibration and changing values.
3. The "P" button is used to print a snapshot of gas reading information. A parallel
printer will need to be connected to the 25 pin connector on the back of the analyzer.
4. The "C" button is used to calibrate the gas analyzer. The calibration procedure will
be explained in detail later in this manual.
