5.3.1.2 Setting parameters for the NF pulse transducer of the gas meter
If a low-frequency pulse transducer is connected in accordance with 5.2.1.1, you can set the
input mode and cp value as follows:
1. Setting the input mode:
 Move the cursor to the "Serv" tab and via the following path to the value "Md.I1" input
mode:
Serv.  Inputs  Input 1  Md.I1
 Press the key combination ENTER  + 

The value set flashes.
 Repeatedly press one of the  or  arrow buttons until the text "Pulse input" flashes.
 Press the ENTER  +  button to confirm the set value. It is possible to abort the
entry by pressing the key combination ESC  +  .
2. Setting the cp value (pulse constant):

Move the cursor to cp value "cp.I1" in the same path
 Press the key combination ENTER  + 

One digit of the value flashes.
 Move the cursor with the arrow buttons  or  to the digits and change these with the
arrow buttons


counter can be set to the same value as the gas counter once when the administrator lock is
open. Setting the volume is always possible when the calibration lock is open.
 Open the administrator lock or the calibration lock
 Move the cursor to the " Serv " tab and via the following path to the value " VmA "
(adjustable volume at measurement conditions) input mode:
