6)Correction of the linearization polynom, if necessary:

·You can optimize the calculated linearization with maximum three additional points.

·Press the ENTER key or the → -key in the line "Midpoint correction set up..." of the menu "Linearization functions" to change to the corresponding submenu:

a) Range selecting:

·Range 1 will be selected automatically after entering the menu. If you want to select another range to correct, press the F4 key (RANGE 2/3/4). The range selected will be displayed in the headline of the menu.

b) Disable the correction:

·You have to disable the correction mode before calculating the correction data. Otherwise, you will have interferences during the calculation with existing values.

·Press the ENTER key or the → -key in the line "Correction" to select the parameter. Set up "DISABLED" with the − -key or the ↓ -key and confirm it with the ENTER key.

c) Measured point selecting:

·Go to the line "Point being measured" with the ↓ -key.

·Press the ENTER key or the → -key to select the parameter. Select "Point 1" with the the − -key or the ↓ -key and confirm it with the ENTER key.

d) Set up the gas concentration for point 1:

·Go to the line "Point 1 gas concentration" with the ↓ -key.

·Press the ENTER key or the → -key to select the parameter.

·Select any digit with the ← -key or → -key and set up the value you want with the the − -key or the ↓ -key. If necessary, change the sign with the F4 key ("+/-").

·Confirm your set up with the ENTER key.

e) Measuring of the gas concentrations:

·Flow the analyzer with the gas concentration set up of the line "Point 1 gas concentration" and measure the raw value.

·After the signal will be stable press the F3 key (SET): The current signal will be displayed in the line "Point 1 reading". But, the analyzer will equate the raw value with the desired value of this point automatically.
