Starting and stopping measurement
The measuring sequence can either be controlled manually with the Start/Stop action buttons or
automatically with a timer.
Starting and stopping measurement at specified time
Measurement sequences can be automated with the timer function of labworldsoft by specifying the
starting and stopping times. In addition, semi-automatic measurement sequences can be defined in
which only one time is effective. For example, a manually triggered measurement can be stopped at a
specified stopping time. It is also possible to manually end an automatically started measurement.
Specifying starting and stopping time
Proceed as follows:
1. Open the dialog box by clicking on the menu command 6WDUW6WRS WLPLQJ ... in the
"Measure" pulldown menu.
The related dialog box is opened. The last valid starting and stopping times are displayed
in the list fields. Both times are initially inactive (empty control fields).
2. Enter the new VWDUWLQJ WLPH at which the measurement is to begin in the list fields.
3. Switch on the starting time with the related control field.
4. Enter the new
VWRSSLQJ WLPH at which the measurement is to end in the list fields.
5. Switch on the stopping time with the related control field.
6. Confirm the entries with

 The current time is entered in the fields "Hours - Minutes - Seconds" (absolute time). The
calendar day (value range: 1 to 31) must be entered in the "Days" field.
 The measurement duration is entered for the stop time (relative time). The number of days,
starting from today, must be entered in the "Days" field:
00 if the measurement is to be stopped today,
01 if the measurement is to be stopped tomorrow,
etc.
 Only one time is active for semi-automatic sequences. The corresponding control field must
be marked.
Setting sampling time
To evaluate the resulting measured values, the data quantities must be known or estimable. This is
particularly important for automatic result recording when results from several channels are written to
data carriers. The parameters "Sampling time" and "Measurement duration" are decisive for the
resulting data quantities.
