5.3.1.2 Adjusting the parameters for the low frequency pulse trans-
ducer of the gas meter
If a low frequency pulse transducer is connected as per 0, adjust the input
mode and the cp value as follows:
1. Adjusting the input mode:
 Move the cursor to the "Serv." register and to the input mode "Md.I1" via
the following path:
Serv.  Inputs  Input 1  Md.I1
 Press the ENTER button  The set value will start to flash.
 Press one of the arrow keys  or  until the text "Pulse input" starts to
flash.
 Press the ENTER button to confirm the set value. The input value can
be deleted by pressing the ESC button.
2. Adjusting the cp value (pulse constant):
 Move the cursor to the cp value "cp.I1" via the same path.
 Press the ENTER button  The value will start to flash.
 Move the cursor using the arrow keys  or  to the digits and change
these using the arrow keys  or .
 Press the ENTER button to confirm the set value. The input value can
be deleted by pressing the ESC button.
5.3.1.3 Activating encoder mode
If an encoder is connected as per 5.2.1.2, the encoder mode is activated as
follows:
Start the "Auto Detect" function using the keyboard of the EK280 as fol-
lows:
 Move the cursor to the "Serv." register and to the value "Md.I1" (input
mode) via the following path:
Serv.  Inputs  Input 1  Md.I1
 Press the ENTER button  The set value will start to flash.
 Press one of the arrow keys  or  until the text "Auto-Encoder" starts
to flash.
 Press the ENTER button to confirm the set value. The input value can
be deleted by pressing the ESC button.
 Wait until "Auto-Encoder" is replaced by another value. This may take
up to one minute as the EK280 consecutively activates and tests all
known encoder protocols.
 Once the EK280 has successfully detected the encoder, it will display
the meter reading of the gas meter with the description "Vo":
Serv.  Volume  Inputs  Input 1  Vo
