Zero Calibration Procedure
1.
Connect the gas to the “Cal Gas Inlet” on the side of the SGA enclosure. It is
recommended to let everything (gas and SGA) sit for approximately thirty minutes to
allow the temperature to achieve equilibrium.
2.
Select “Sensor Calibration” from the Main Menu.
3.
Tap “Zero/Span” and use the “Toggle Zero/Span” button to select Zero.
4.
Tap to highlight “Enter Gas Concentration” and tap the “Enter Gas %” button.
5.
Enter the appropriate concentration of the calibration gas (in this case 0% since it is a
zero calibration).
6.
Begin the flow of gas and allow the readings to come to equilibrium. This occurs when
the actual values are not moving in a specific direction, and they display only slight
movements up and down. This should take approximately 45 seconds.
7.
At this point, tap to highlight “Run Calibration” and tap the “Run Calibration” button.
8.
The Calibration Timer on the screen will count down, and when it reaches zero the
Current gas value will adjust to match the Gas concentration.
Span Calibration Procedure
1.
First tap “Zero/Span” and use the “Toggle Zero/Span” button to select Span.
2.
Tap to highlight “Enter Gas Concentration” and tap the “Enter Gas %” button.
3.
Enter the appropriate concentration of the calibration gas (see note on p.15).
4.
Begin the flow of gas and allow the readings to come to equilibrium. This occurs when
the actual values are not moving in a specific direction, and they display only slight
movements up and down. This should take approximately 45 seconds.
5.
At this point, tap to highlight “Run Calibration” and tap the “Run Calibration” button.
6.
The Calibration Timer on the screen will count down, and when it reaches zero the
Current gas value will adjust to match the Gas concentration.
