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.
