50 Assembly, Connection and Putting into Operation
 Change the value using the arrow keys  or  to „1“
 Once you have changed the value, press the ENTER key in order to
confirm your entry. The entry can be cancelled by pressing the ESC
key.  „Vm“ is assumed for „VmA“.
If, when the administrator lock is open, the assumption of
„VmA" for „Vm" is rejected with the message –13--, then this
process has already been carried out once.
Other changes are possible if the calibration lock is open or, if
the administrator lock is open, after deleting the change infor-
mation for comparison of „Vm" with the gas meter (see chap-
ter 5.3.1.7).
5.3.1.7 Deleting change information for comparison of Vm with the
gas meter
In order to allow the volume at measurement conditions to be reset if the
administrator lock is open, the change information for comparison of "Vm"
with the gas meter must be deleted:
 Open the calibration lock
 Move the cursor to the „Serv.“ tab and go to the value „Clear“ (deleting
change information) via the following path:
Serv.  Volume  Actual volume  Synchronization Vm  Clear
 Press the ENTER key  „0“ flashes.
 Change the value using the arrow keys  or  to „1“
 Once you have changed the value, press the ENTER key in order to
confirm your entry. The entry can be cancelled by pressing the ESC
key.  „TimeX“ (time stamp of comparison), „Vm_o“ (Vm old value),
„Vm_n“ (Vm new value) are set to default value.
5.3.1.8 Setting the volume at base conditions
For the EK280 volume conversion device, there is the option available
when commissioning the device to set the volume at base conditions meter
once if the administrator lock is open. It is always possible to set the vol-
ume if the calibration lock is open:
 Open the administrator lock or the calibration lock
 Move the cursor to the „Serv.“ tab and go to the value „VbA“ (adjustable
volume at base conditions meter) via the following path:
Serv.  Volume  Standard volume  Synchronization Vb  VbA
 Press the ENTER key  One of the value digits flashes.
 Move the cursor using the arrow keys  or  to the digits and change
these using the arrow keys  or .
