Date and Time
When MetStream is first powered up it opens with a default Time Zone, default
01/01/2000 date, zero hour time and default NTP.
Select the required Time Zone from the drop down menu and click on ‘Save Time Zone’.
Type in the required Time and Date into the relevant boxes and click on ‘Save Time &
Date’.
It is important to choose the required Time Source carefully to ensure that data logging
will take place.
Default ‘Change Time Source’ setting is NTP (see Notes below).
If PTP enabled (see Notes below) the screen will show:-
Notes:
Manual
Time, for non-networked units, relies on MetStream internal clock.
If MetStream power is lost for more than a day then clock settings will be lost and logging
will halt. Upon return of power Manual time settings will need to be reset.
Network Time Protocol
(NTP) recommended setting for network connected PC’s which
can obtain time synchronisation over the internet.
NTP setting will not pick up time if a direct Ethernet connection is being used with a PC.
If NTP selected but no connection to NTP source made then the unit cannot log data.
Precision Time Protocol
(PTP) looks for the network provider master clock for specific
closed networks.
PTP options data will show the IP address of the PTP source.
