6.2.1.18 Power failure period
The total duration of the period (s) (in hours, minutes and seconds) from the measurement start during which the
meter was not energised.
6.2.1.19 Date
The display shows the actual calendar date.
6.2.1.20 Time
The display shows the actual time of the day.
6.2.2 Parameter setting mode
When selecting the parameter setting mode (see section 6.2.1), the operator will be requested to enter
a four-digit password.
6.2.2.1 Password
The first display line will read
PASSWORD
and the first digit position on the second line will display 0. Depress push-button T3 repeatedly to increase the number
by 1 at a time (after 9 will follow 0 again). Select the correct number at the first digit position and then depress push-
button T2 to move to the second digit position and repeat the number setting procedure with push-button T3. Progress
to the third and fourth digit positions and enter the correct password – a combination of four numbers (see the
schematic diagram in Fig. 19).
Confirm the entry of the correct password by depressing push-button T4. Provided the password entered is correct,
the system will proceed to the language selection block. In the case of an incorrect password the system will request a
new password entry. After three consecutive entries of incorrect passwords the system will switch over to the data
display mode and will not permit further entry into the parameter setting mode. A new attempt at the password entry is
only possible after system de-energising and repeated switching on of the power supply.
Should the operator forget the password, it is possible to use the manufacturer’s password supplied with the system
(0200). This shall be done as follows: switch off the power, depress and hold push-button T4 and switch the power on
again.
The user password can be changed at any time in the parameter setting mode using the procedure described in
section 6.2.2.5 below.
6.2.2.2 Meter setting procedures
The meter parameters that can be defined or re-defined in the parameter setting mode include: the language of the
messages appearing on the display, units of the displayed quantities, the user password required for entry into the
parameter setting mode, the initial measured quantity, specified values of some measured quantities (q
s
, impulse
number – litres per imp., threshold/sensitivity level, and the maximum/limit values of fluid flow rate, volume and
temperature), as well as the date, day of the week, time of the day, start of the measurement period and meter zero
position (only with the technological meters).
The procedures to be used in setting particular parameters are described below. Upon initialisation of
a particular parameter setting mode, the name of the function block concerned will appear on the first line of the display
in block letters, e.g.
