
At Active Detector No. enter the detector for which you want
to record the plateau.
–
Detector No. = 0 selects the master detector.
– Detector No. = 1 selects slave 1.
– etc.

At
HV Start
enter the high voltage (e.g. 500V, minimal 300V),
where the plateau measurement should start and confirm the
input with
ENTER .

At
HV Stop
enter the high voltage (e.g. 1000V, minimal
1300V), where the plateau measurement should stop and con-
firm the input with
ENTER .

At
HV Step
enter the step size between the measurement
points (e.g. 50V) and confirm by pressing ENTER .
The step width determines the number of value pairs. The
larger the step width, the lower the number of the value pairs!

At
Meas. Time
enter the time how long a measurement point
should be recorded or the count rate is to be averaged (e.g. 20
s) and confirm the entry with
ENTER .

Transfer the entries with SEND .

HV Mode
to start the plateau measure-
ment.
The plateau measurement is started. For this purpose, the
measuring mode is exited and the plateau of the multiplier
which is used in the detector is measured.
During the plateau measurement the values of the following param-
eters are updated continuously:
• HV Live : HV value of the voltage at which the count rate is
being measured.
• Cps Single Detector: Count rate of the selected detector.
• Cps Live : Total count rate of all detectors.
At the end of the plateau measurement the detector automatically
switches back to
HV Mode : AUTO or MANUAL , depending on
which mode was last set.
The plateau measurement is now complete and can be viewed and
reviewed under
Plateau View as a table or plateau curve.
