This function allows to select explicitly all parameters for different types of gas, which are stored in
the sensor. You can see only those gases which the sensor is scheduled for.
1. Activate of menu point LMAS.
2. The display shows the presently set type of gas.
This reading can also be selscted in the standard service menu.
3. Use keys
ZERO

and
SPAN

to set the gas.
In the standard service menu the display shortly reads fAiL and then the presently set
type of gas (step 2).
4. Select the desired type of gas and confirm by pressing key
QUIT
MENU
briefly.
5. The CC28 is re-starting (RSET) (only for selection of a different gas).
If the type of gas has been changed several times before the user returns to a gas which was already
parameterized before, the transmitter takes over those parameters which were stored by the user
before.
If the type of gas has been changed and after a restart, the stored standard parameters (see table on
page 30) are taken over for a type of gas which is selected for the first time.
When the type of gas was changed, the zeropoint has to be adjusted in any case by means of the
AutoCal function. The sensitivity of the sensor for the new gas is to be checked as well and to be
adjusted by means of the AutoCal function, if necessary.
The different gases will be indicated either as shown in the list below.

Menu point SCAL – Adjustment of full scale deflection (only possible in extended menu)
The detection range can be set to 50, 75 or 100 % LEL. The detection range for ammonia (4 Vol.%)
cannot be changed.
Follow the 5 steps described below:
1. Activate menu point SCAL.
2. The display shows the presently set full scale value.
In the standard service menu the display reads "100" for 100 % LEL.
3. Use keys
