Multi-Tech Systems 7600 Set Meter Time, Use this item to set the meter’s display to local time

DST Offset (hh:mm)

This setting determines the daylight savings time offset applicable to your location. The DST offset is the amount of time that the clock is moved when Daylight Savings time begins or ends. For example, an entry of +01:00 sets a daylight savings time offset of one hour. Setting DST offset to 0 (zero) disables daylight savings entirely. Specify a positive (+) or negative (–) offset with the Navigation buttons. The value must be non-zero before you can change its sign.

NOTE

The Clock Module’s DST Start and DST Stop setup registers control the start and end times for Daylight Savings for up to twenty consecutive years. These registers are already configured in the factory. To change them, you must use Designer.

Sync Type

This setting specifies whether time synchronization signals are received in UTC (Coordinated Universal Time) or Local Time. The default is set to UTC for ION Enterprise. Some DNP masters use Local Time.

Sync Source

This setting determines the port responsible for receiving the time synchronization signals. Only signals received on the selected port are used to synchronize the meter’s internal clock; time synchronization signals on all other ports are ignored. The choices are ETHERNET, COM1, COM2, and COM3. The default is COM1. Refer to the Time Synchronization and Timekeeping technical note for more details on synchronization sources.

Clock Source

This item determines the time synchronization source. The meter clock can be synchronized externally from the line frequency (Line Freq), or from an internal crystal (Internal), or through a communications port (COMM). The default is Line Freq. If you are using GPS time synchronization, change this setting to COMM.

Set Meter Time

The Set Meter Time sub-menu contains settings for the date and time displayed on the front panel. The Meter Time settings are dependent upon the configuration of the Clock Setup menu–-you must set the time zone offset (TZ Offset) prior to setting the Local Date and Time.

Local Date

Use this item to set the meter’s display to the current date. The format of the date is defined in the General Format Setup menu.

Local Time

Use this item to set the meter’s display to local time.
