Activation of SO
2
Measurement
If you have an instrument without SO
2
measurement, but with the serial number 12-0000 or
higher, then your instrument is “SO
2
ready”. Meaning, in order to enable the SO
2
measurement
only the installed measurement cell cover needs to be replaced with an SO
2
sensor. Please
follow the instructions in chapter ‘Replacement of SO2 Measurement Cell’ on page 29 to in-
stall the SO
2
sensor. In addition to installing the SO
2
sensor, you will need to activate the SO
2
measurement as follows:
Press the lower right menu key repeatedly to select the
Other Settings menu.
Then press the Activation Codes key.
A window will appear where you can enter the activation
code provided by the manufacturer or your local supplier.
Press Ok after entering the code.
If the correct code was entered, a window appears con-
firming the activation of the SO
2
measurement.
The instrument recognizes the type of the sensor fitted
and displays its ppm range.
Press Ok and the window will disappear. The instrument
is now ready to perform SO
2
measurements.
If a wrong code was entered, a window appears indicating
that the code is not valid. Press
Ok and try again.
In the event that the code is not accepted, please contact
the manufacturer or your local supplier.
