user. In particular, in this mode counters of entries into ‘Setup’ and ‘Verification’ modes are
displayed.

’Setup’ mode is used during meter commissioning for hydraulic zero setting in volume
measurement channels, input of necessary parameters (pressure, etc.), and also for choosing
an appropriate mode.
It should be considered that in account modes “In account” and “Stopped” menu of
‘Verification’ mode is blocked. In addition, those items of ‘Setup’ mode which should be
unchangeable during process of measurement are also blocked.

’Verification’ Mode is used to evaluate measuring errors and calculating errors of ba-
sic meter performance, and also to check correctness of their indication.
’Verification’ Mode is used for automation of water meter performance verification in
case of regular verification. Verification is conducted only by authorised personnel.

Entry into service modes ‘Setup’ and ‘Verification’ is permitted only after entering

Table 11.1
MODE STANDARD PASSWORD

On customer’s demand the manufacturer can set
INDIVIDUAL PASSWORDS for
service modes, that is equivalent to additional ELECTRONIC SEALING of the calculating
unit and provides inaccessibility of unauthorized users to saved up measuring information.
The password is represented by 8-digit integer number to get access to one of service
modes.
Symbols «- » on the indicator mark bits for entering password digits.
Non-masked (open) value of input digit is displayed only in that digit place, in which
input of its values (editing) is provided.
While entering a password, press the button "To the right" to move the cursor on one
digit place to the right. It allows to change any digit of the password.
Pressing buttons «Up» and «Down» leads to a change in the digit value.
Pressing the button «To the left» means ending of password entering.
If during 2 minutes there was no pressing any button the meter switches from ‘Enter
password’ mode to ‘Indication of main parameters’ mode.
On figure 11.1 the way to run ‘Setup’ mode is given.
