3.3 Device Real Time Clock Synchronisation
[Tools][Synchronise Device RTC]
Use this feature to synchronize the real time clock in the connected device to the PC clock. Select
[Tools][Synchronize Device RTC] to begin the process.
Ensure that the time and date on the PC are correct (and take into account any
daylight saving offsets) before synchronising the device.
PC Time/Date
The current time and date of the PC. The format is hh:mm:ss dd/mm/yy
Device Time/Date
The time and date of the device. This will display ‘Update Paused’ if ‘ Read
Device Clock ’ is not enabled. See below.
Read Device Clock
Tick this box if the device Date/Time is to be read from the device
continuously and displayed for the duration of the connection.
Offset
Used to set a time offset between that of the PC and the location of the
device. This may also be used if the PC time is set for daylight saving.
The device must be set for standard time so as to match with the standard
time setting of the monitoring station. The offset range is –12 to +12
hours.
[ Sync ]
Click this button to synchronise the Time/Date of the device to that of the
PC, inclusive of the time offset.
After carrying out the synchronization, the PC Date/Time and the Device
Date/Time should correspond (allowing for any offset) to an accuracy of
±
1 second for a direct connection. The difference could be up to +/-3
seconds if communication is over a slow link such as radio.
