The trigger starts the measurement. First choose the source of trigger . Trigger sources can be
measurement values, digital inputs, status of inverter, etc. The starting conditions are defined
by
trigger level resp. trigger edge .
ATTENTION
The increments of the trigger levels are different depending on the trigger source. Therefore
not every value can be set. After starting a recording, the closest possible values is calculated
and set.
Time between two measured values is set by sampling rate . Numbers of measured value s and
sampling rate define the time of sampling .
The Pre-trigger/Delay set the beginning of the measurement in relation to the trigger event.
Note:
The dynamic of measured values defines the best rate of sampling: fast changing values need
a low sampling rate. The number of measured values defines the time of sending the values
from inverter to
NORD CON .
3. Sampling modes
The oscilloscope has 2 differently modes. The user can choose between "Single" and "Roll"
mode. The "Single" mode is the standard mode. In this mode starts a recording with the current
