Correction factor: You can use this function to make a correction between the static
adjustment of the scale and the dynamic result. Each valid trigger result is multiplied by
the correction factor.
Start with post-trigger and external signal
Select Pre-Trigger as the Trigger mode. This mode requires an external trigger signal
received, for example, before the sample leaves the scale.

Fig. 7.16 Sequence of a measurement (example)
The graphic shows the different times that occurred during the measurement in
simplified format for which you must find suitable values. The external trigger triggers on
a rising edge. You can change the values after a recording via the cursors and the input
fields; the two are synchronized.
Signal edge: Specify whether the level, such as from a light barrier, rises or falls when the
sample passes the light barrier: Rising edge active (switch green) or not.
Measurement time: Define how long the measurement should or can continue before the
product to be weighed leaves the belt.
Delay post-trigger: You can use the post-trigger delay to prevent recording of measured
values in the ring buffer from being stopped too soon, for example because the object
has already passed the light barrier but has not left the belt yet. This allows you to make
use of the longest measuring time possible.
Post-trigger tolerance: The tolerance is used to determine how many measured values
from the ring buffer will be used to calculate the measurement result. Only the measured
