Setting the Logger Clock
The logger has an internal clock that is updated every second. During logging, the time stamps of the data samples
are set by this clock.
When the logger is in power down state, the real time clock is not running. When the real time clock is stopped, and
you setup your logger to log, the Interface Software automatically matches the logger clock to your computer's
clock. You can also manually set the logger's real time clock, using the Interface Software
To set the logger's Real Time Clock, select Set Clock... from the Logger menu . Make sure that "Use Windows
Clock" is unchecked, then enter the current date and time in the appropriate fields. If the "Use Windows Clock" is
checked, the logger's real time clock will be matched to your Windows clock.
Note: You cannot set the logger clock while logging is in progress.
