Then select the menu item
SIMEAS R
in the
Set time at
section and enter the
Cycle Time
. The
cycle time defines the time intervals at which the SIMEAS R-PMU is set to PC time.
The SIMEAS R-PMU time can be set in connection with the cyclical data query. It is not
necessary to set up a separate connection for time setting.
Note
Time setting does not meet high precision requirements because time deviations occur due to
the unsynchronized RTC. The highest accuracy achieved is ±1 s. This is why an external
synchronization using a GPS timer or the minute pulse is recommended.
Note
To prevent the measuring system from being impaired by too frequent time setting procedures,
the minimum cycle time for automatic time setting is 4 hours.
