If this icon is displayed, someone has logged on and is working with the device. If it is not your
login, you should also take no action to prevent the work. (See chapter 7.3.6 for more information).
In fiscal metrology measurement you habe to protect settings which influence the measuring
properties. This is done with the Security Switch (short: SSW). The SSW is a physical connection
(jumper) inside the device.
The absence of this fuse is indicated by the icon of the padlock
, which then appears on each
display. In the delivery state and in "non-official operation", this connection is open and the icon
is displayed.
To close the SSW, the housing has to be opened; this may only be done by
authorized persons of Elster GmbH. You can also arrange for a seal to be
attached to the jumper to detect unauthorized access. Please contact Elster
GmbH if you want to change the SSW status.
7.3.2 Operation mode: Analysis (automatic analysis normal operation)
After the supply voltage is switched on, and when the working temperature is reached, the
measurement beginns autonomously a continuous loop and gives values once per second. Gas
flow is indicated by the flowmeter.
On the device and on the remote operation panel, the “
Main
display
” is shown. „
Analysis
” is
displayed on the display (for Operation and Step), values are displayed in black. The status LED
light up continuously.
Apart from the operator's intervention, the analysis is interrupted regularly by the automatic
operational calibration, see chapter 8.3.

7.3.3 Operation mode: Operational calibration (manual)
The device must perform an operational calibration every week. This calibration
usually runs fully automatically
See chapter 8.3.4.
It is also possible to perform an Operational Calibration manually. This is only useful as long as
the sensors are in an operational range. If the device is in automatic normal operation, login as
described in section 7.3.6 and perform the following steps:
Working steps for manual operational calibration
