Time and timekeeping 9410 series
network is required to implement a GPS scheme. For IRIG-B, one of your meter’s
digital inputs must be connected to the IRIG-B network, and the digital input must
be configured for IRIG-B time synchronization in addition to configuring your
meter’s clock.
NOTE: Use the digital inputs located on the meter base for IRIG-B time
synchronization and other high-accuracy applications.
• GPS over serial: A GPS receiver can synchronize the time of a meter up to ± 1 ms
of Coordinated Universal Time (UTC). For GPS over serial, your meter’s serial port
must be connected to a GPS receiver, and the serial port communications must be
configured with the correct protocol setting.
• Network Time Protocol (NTP): NTP can typically synchronize the time of a meter to
± 10 to 100 ms, depending on network configuration. To implement NTP time
synchronization, your meter must be connected to an Ethernet network that has an
active NTP server and be configured with the server’s information.
Configuring time information using your meter’s display
Use the meter’s display to configure a variety of time parameters.
1. Go to Setup Menu > Date/Time/Clock Setup > Date & Time Setup .
2. Configure your time and date formats, time zone offset, and daylight savings time
offset. Press the down button to access the Clock Setup screen.
3. Configure the clock and time synchronization source, and the time synchronization
time format.
Date/Time/Clock setup
You can configure your meter’s date, time and clock parameters using the display.
