Clock/Battery
The internal clock of the GridVis
®
collector is supplied
with power by the lithium-ion battery.
When the GridVis
®
Collector is switched off, an additio-
nal soldered-in battery supplies power to the clock.
8. 1 Clock
The GridVis
®
Collector is delivered with the clock con-
figured and it can be synchronized during operation by
an NTP server (Network Time Protocol – standard for
the synchronization of clocks in computer systems).
An NTP server of the PTB (Physikalisch-Technische
Bundesanstalt - ptbtime1.ptb.de) synchronizes the
time whenever the GridVis
®
Collector connects to the
Internet.
NOTE
To synchronize the internal clock of the GridVis
®
Col-
lector, your company firewall must enable the address
"ptbtime1.ptb.de"
.
Contact your system administrator for this enable
and for the correct settings!
The accuracy of the internal clock is +/-15 s per month
at a temperature of 0 °C to 40 °C (32 °F to 104 °F).
Function planned for mid-2019:
The clock provides date and time information to confi-
gure the time of the measurement devices.
8. 2 Battery
The typical battery life is 5-8 years. As with the lithium-
ion battery, it can only be replaced at the factory.
