8 Setup on the Web Server Pages
CLOCK SETUP
The Power Xpert Meter uses a real-time clock for time keeping. The meter can be configured to
adjust for Daylight Savings Time (DST) based on the time zone selection and to synchronize time
using NTP. By using NTP, time will be maintained by the real time clock, and the real time clock will
be calibrated and time corrected using NTP.
Note: The initial clock setting is in UTC/GMT (Greenwich Mean Time). The user-selected Time
Zone only takes effect after clicking “OK”.
The Clock setup allows you to set the time in hours and minutes, select a time sync option, and set
the date for the meter. If NTP is selected for time synch, an IP address of the NTP server should be
set. When selecting DCF-77 as the Time Sync Source, an Input channel must be selected under
Meter Setup & Commissioning -> I/O. When selecting NTP (Network Time Protocol) as the Time
Sync Source, at least one IP Address must be entered (as many as three NTP server IP addresses
may be entered).
Note: In order to retain the clock setting through a power cycle, the battery back up must be en-
gaged. Set Switch D3 to the On position to engage the battery (See cover on power supply; Fig.2).
