Data Log Event
The data log event is the occurrence that triggers data to be sent to either internal
memory or the printer/computer via the serial port. There are eight options, making
this a useful and comprehensive function.
Disabled: Effectively switches data logging functions off.
Manual: Data logging is triggered from a press of the Store [STO] key only.
Timed Interval: Data logging is triggered on a period set by the Data Log interval.
Endpoint Detection: Data logging is triggered when the sample measurement
reaches stability – this can be used to enhance productivity when measuring batches
of samples by having the results automatically printed or stored without the operator
having to even press a button.
Timed after Endpoint: Data logging is triggered at the entered data log interval but
only after the endpoint detection – this enables data from reactions or slowly
changing sample streams to be logged with more control.
Alarm Set: Data logging is triggered when one of the alarm conditions is reached.
This is useful for tracking time/date of problems occurring.
Alarm Clear: Data logging is triggered when one of the alarm conditions is cleared.
This is useful for tracking time and date when problems are cleared.
Alarm Set & Clear: Data logging is triggered when one of the alarm conditions is set
and also when they are cleared. This gives useful data for analysing problems or
control functions.
