In the menu "Span Gas Definition" you can set up the default value for each range of the current channel, the actual span gas concentration and the desired span gas unit. The concentration of each range should be a value between 70 and 110% of the end of range value.

Set up parameters:

¨Select any line of variables with the ↓ -key or the − -key.

¨Select the variable with the 8 -key or the → -key.

¨Select any digit with the ← -key or the → -key and adjust a new value with the − -key or the ↓ -key

resp. select the whole parameter with the − -key or the ↓ -key.

¨Confirm the new value with the 8 -key or

cancel and go back to the last value with the F2 key.

The last two lines of variables:

These lines are only information lines. The variables cannot be changed.

Note:

The "ppm ® "mg/Nm3" conversion factor can be set up in the menu "General Concentration Measurement Setup" (see section 5.1.10 p. 5-54)!
