Plateau Measurement.
For information on how to perform a plateau measurement please
refer to chapter 6.2, page 3-406.
1 Active Detector No. Choose the detector for which you want to record a plateau.
• Detector No. = 0 selects the master detector.
• Detector No. = 1 selects slave 1.
•etc.
2 HV Start Enter the HV start value in volts.
3 HV Stop Enter the HV stop value (end value of the measurement) in
volts.
4 HV Step Enter the step size in volts, which should lie between the mea-
suring points.
5 Meas. Time Enter the length of time over which each measuring point
should be averaged, for example 20 s.
6 HV Mode The menu item offers the following options:
• AUTO
Enables the automatic HV control. Set this operating mode for
the normal measurement mode. This enables a temperature-
stable operation of the detector.
• MANUAL
This setting is typically used for testing purposes only. You can
specify, for example, the provisional operating point of the
detector. The specified voltage must, however, lie in the pla-
teau.
As soon as you enable Manual, the automatic HV control is
switched off. The HV is then set to the value that was specified
at HV Manual.
• PLATEAU
Starts the plateau measurement. The measurement mode is
exited and the plateau of the multiplier which is used in the
detector is measured. The measurement is done with the set-
tings defined in the menu items
HV Start, HV Stop, HV Step
and Meas. Time.
At the end of the plateau measurement the detector automati-
cally switches back to HV Mode: AUTO or MANUAL, depend-
ing on which mode was last set.
