Start VBias [V] Lower voltage for plateau curve. At this voltage the
plateau recording will start.
Stop VBias [V] Upper voltage for plateau curve. At this voltage the
plateau recording will stop.
Sampling Time [s] Time used for sampling of each point. Should not be
smaller than 20s.
Steps [V] Voltage between two points for plateau sampling.
Cps Meas. Pulse Rate of actual indexed plateau entry in plateau table.
VBias [V] V
bias
of actual indexed plateau entry in plateau table.
NOTICE
The Sampling a plateau curve is only needed for checking the correct function of
the detector. When operated in automatic voltage control mode the plateau is
not needed otherwise.
NOTICE
Record plateau curves at room temperature only. The assembled plateau will not
be comparable to other plateaus otherwise.
Record Plateau
The values in the window "Plateau Setup" are pre-set by Berthold on delivery and
can be used in most situations.
1. Place source in front of detector.
2. Click on the Button <Start Plateau> .

The Plateau measurement is started.
3. The plateau record is complete when the progress bar is complete and the
window closes automatically.

The recorded values are displayed in the table and the characteristic curve
is displayed.
The determined plateau curve is displayed in a diagram. The pulse rate in-creases
with increasing voltage. This must form a unique plateau. If a too short or too steep
plateau is detected, the detector is operating in an unstable manner.
