menten dieses Buches, sobald eine Synchronisierung des gesamten Buches(!) durchgeführt

4.4.3.17 Time
The Energy Analyser 550 has a clock with a battery backup. The fault in the clock’s quartz is aligned with
room temperature during production so that the clock only deviates by +-1 minute/month. If transient records
and event records are to be compared with other measurement records, it is recommended that the time in-
dicated by the Energy Analyser 550 be compared and aligned with that in a time server via an Ethernet con-
nection. For synchronisation, the Network Time Protocol (NTP) is used.
• Mode
Off - synchronisation of the clock with an external time server is switched off.
Lists - The Energy Analyser 550 is waiting for time information from a time server.
Active - The Energy Analyser 550 automatically requests time information from an NTP server every 64
seconds.
• NTP server - this is where the time server’s address is input.
Time setting
• ThetimecanberesetduringcongurationbyadoptingtheUTCtimefromtheconnectedPC.
4.4.3.18 Time zone
All time information with regard to measurement values, events and transients relate to UTC time (Coordi-
nated Universal Time). ecoExplorer go converts UTC time to Central European Time (CET) when it displays
measurement results. Central European Time (CET) is the applicable time zone in central Europe and there-
fore also in Germany.
• Winter time - time offset from Central European Winter Time relative to UTC time.
• Summer time - time offset from Central European Summer Time relative to UTC time.
• Start of daylight saving time - start of daylight saving time.
• End of daylight saving time - end of daylight saving time.
4.4.3.19 Inputs
The Energy Analyser 550 has eight digital inputs. These inputs can be used as digital inputs and as input
pulse meters
• A pulse value can be assigned to every pulse input.
