The SL200 temperature logger has an internal Real Time Clock. This clock is updated every second. During logging, the time stamps of the temperature samples and of the temperature alarm occurrences, are set by the Real Time Clock.
To set the logger’s Real Time Clock, from the Logger menu select Set Clock….
As a security measure you can not set the Real Time Clock while logging is in progress. You must end logging before the Real Time Clock can be set.
The window below helps you set the Real Time Clock of the SL200.
