11 The operating procedure
11.1 Requirements to the personnel .
The maintenance personnel should be completely acquainted with present OM.
11.2 Structure of the menu of control of the meter.
Control of the meter (a readout and specification of operating mode and meter parame-
ters) is carried out by means of proper menu item selection.
Items of Menu are displayed in the top row of meter indicator.
Use of the menu (switching of items) allows to get the information about measured pa-
rameters values, parameters of the meter and also to carry out meter verification.
Selection of menu items and changing (input, setting) of parameters is carried out by
pressing buttons on the calculator. Sequence of operations to select the certain menu item
and to input parameter value or to select a parameter from the list is given in the Appen-
dix D.
All measured quantities, meter parameters and commands for meter control are com-
bined in some sections – modes of control of the meter.
Some service modes (‘Setup’, ‘Verification’) are protected from non-authorized access
by the password.
The meter modes are given in the Appendix D
.
11.2.1 ‘Indication of main parameters’ Mode.
The device switches to ‘ Indication of main parameters’ mode after battery installa-
tion, after device set-up in ’Setup’ mode , after ending of work in service modes ( ’Check’ ,
’Verification’ ), and also at automatic returning to ‘ Indication of main parameters’ mode if
buttons are inactive.
Depending on meter configuration the proper measured parameters, which meet to a
given configuration, are displayed on the calculator indicator.
In this mode error messages are shown on display.
Meter has three
accounting mode:
−
“ Not in account ” – this is initial mode. In this mode it is possible setup some para-
meters in “Setup” menu. This mode indicated by periodically display text “ no rSt ”;
−
“ In account ” mode. This is main mode for accounting. There is no additional indica-
tion for this mode.
−
“ Stop ” mode. This mode can be activated, when no water in pipe for long period,
etc. In this mode no data are placed in archive and no errors indicated.
11.2.2 ’Errors’ Mode.
The menu of this mode is appeared only if some errors in device functioning take place.
This mode is used for presentation of complete (not only code, but text) information about
running errors. It is possible to see all registered to this moment errors.
Doesn’t have impact on measuring process.
11.2.3 ‘Indication of additional parameters’ Mode.
This mode is intended for displaying of minor (rarely viewed) measuring magnitudes. It
doesn’t have impact on measuring process.
While working in ‘ Indication of main parameters’ and ‘ Indication of additional pa-
rameters’ modes in worst-case situations the code and explanation of the failure is dis-
played (see Chapter 13).
