·Change to the line you want with the -key or the -key.

·Select the tag of the reference channel with the 8 -key or the -key:

The display will go back to the menu "Differential Measurement" automatically. You can see the channel selected in the line "Source channel".

3)Status determination of the reference channel:

·Change to the line "Source concentration" with the -key or the -key and press the

8 -key or the -key to select the parameter. Adjust the parameter with the -key or the -key and confirm it with the 8 -key.

·Use actual value:

The reference value to calculate the difference concentration will always be the current value of the reference channel.

·Use stored value:

The reference value to calculate the difference concentration will be fixed during the whole differential measurement.

4)Give up reference gas to the reference channel:

·You have to give up a defined concentration of the measurement gas to the reference channel to determine the reference value.

·If the reference signal is stable, you have to change to the line "Store source con- centration !" with the -key or the -key. Press the 8 -key or the -key to start this function. If asked, confirm with the F2 key (Yes) or cancel and go back to the menu page with the F4 key (Back...) or the -key:

The current signal will be fixed for the differential measurement.

5)Give up measurement gas to the measurement channel:

·You have to give up the measurement gas to the measurement channel while the reference signal is stable to measure the differential concentration.

6)Enable the differential measurement:

·Press the 8 -key or the -key in the line "Function is" and adjust "Enabled" with the

- -key or the ¯ -key. Confirm it with the 8 -key:

The differential measurement will start and the differential concentration will be determined.
