3.7.1 Synchronization Input (SYNC-IN)
If a third party device is connected to the synchronization input SYNC-IN then depending
on the setting of the configuration window from the application software the measurement
will start/stop or “sample by sample” synchronized by a signal from the third party device.
Input is protected against faulty polarisation and pin 1 is set to +5V ("1") by an internal pull-
up- resistor (2.7 k
). If this input is set to 0 V ("0") i.e. by a switch or break contact than the
SYNC-IN is triggered.
