Daylight Saving Time
When the daylight saving time is enabled, the meter automatically
advances the device clock by one hour when daylight saving time begins
and puts the clock back one hour when it ends. The default daylight
saving time change points are preset for the U.S.A.
The daylight saving time option is disabled in the PM130 by default. If the
daylight saving time option is disabled, you need to manually adjust the
device clock for daylight saving time.
Time Synchronization Pulses
External time synchronization pulses can be delivered through one of the
digital inputs.
If a digital input is selected as the time synchronization source, the edge
of an external pulse adjusts the device clock at the nearest whole minute.
The time accuracy could be affected by the debounce time of the digital
input, and by the operation delay of the external relay.
