¨Input of the desired values:

·You will need minimum 6 values to calculate a polynomial curve. In the menu "Gas concentration" are maximum 20 values available.

·Press the ENTER key or the → -key in the line "Gas value" of "Point 1" to select the parameter.

·Set up the concentration you want with the − -key or the ↓ -key. If necessary, change the sign with the F4 key ("+/-"). Confirm your input with the ENTER key. It is also possible to select the digits with the ← -key or the → -key and to change the number with the − -key or the ↓ -key.

¨Measuring of the raw values:

·Flow the analyzer with a defined gas concentration.

·After the signal will be stable press the F3 key (DATA): The analyzer will store the desired value and the corresponding raw value as "Point 1" to calculate the linearization polynom.

¨Repeat the procedure described to get all values you need to calculate the polynom:

·Go to the line "Gas value" of "Point 2" with the ↓ -key and set up the desired value.

·Go to the line "Point to be measured" with the ↓ -key and select "Point 2".

·Measure the corresponding raw value, store the values with the F3 key and so on...

¨To set up the values of point 3, 4 and all the other points you have to change to further menu pages with the F4 key (NEXT). You can always go back to the last menu page with the F2 key (ESCAPE).

5)Calculation of the polynomial function:

·You can calculate the linearization polynom in the following way, after you will be ready with the registration of the points:

·Go back to the menu "Polynomial set up" with the F2 key (ESCAPE) or the ← -key. Then, press the F3 key (CALC): The analyzer will calculate the polynom with the available points and store the coefficients of this function for the range selected.
