Clock
Device is equipped with real time clock. Synchronization of clock is possible via:
-
automatically (2G/3G/4G modem is required and must be configured to cyclically connect to
GSM network)
-
PUSH mode
–
time can be set using any interface (port) to access the device: keyboard,
COM1 and COM2 (RS485), optical interface (IEC 62056-21), NFC and modem.
Information about clock modification is saved into device’s events memory (time before and after
modification). Access to time modification with use of keyboard is protected by password.
An option is available for automatic change to summer/winter time. Change of time can be realized
automatically, according to built-in calendar or manually, by setting new time by user.
Change of time both automatic and manual has no influence on gas volume counting in main
counters
Vb
and
E
. An event
Time changed
will appear in device memory in case of changing time in
configuration of automatic change to summer/winter time.

Clock adjustment modes
There are three modes of clock adjustment:
-
RTCMode
=1 (
URGENT
mode)
–
all time settings are immediate. In this case, regardless of the
size of the step change time, the event archived in the TimeLOG is always generated.
-
RTCMode
=2 (
OPTIMAL
mode)
–
mode with registration protection and with accelerated step
response to clock setting requests. In this mode, the delay of response to time settings is
typically relatively short and results only from the protection of periodic and hourly
registration.
-
RTCMode
=3 (
FLUENT
mode)
–
all time adjustments are sent for smooth tuning of the clock.
In this case - when the time difference does not exceed maximum permissible deviation -
there is no sign of tuning the clock in TimeLOG. When the time difference exceeds
permissible deviation - in a properly selected moment there will be a step change of time,
and information about it will go to TimeLOG.
