Plateau
Start Plateau
You can automatically measure a plateau of the detector in steps
of 60 V, e.g. to check the correct function of the NaI crystal-
multiplier combination.
Check Plateau
The value pairs of the plateau measurement can be displayed here
and plotted as a curve for evaluation.
Adjust current i/o.
Adjust current out
Adjust current output to the values 1.8 mA
and 18 mA by increas-
ing or reducing the numerical value on the display.
Adjust current in
Calibration of current input. Feed current of 1.8 mA. Confirm dis-
play with <enter> and go on with <more>.
Then feed current of 18 mA, confirm with <enter> and go on with
<more>.
Note: The current input calibration is omitted when the test input
is configured as pulse input. In this case, this input is used as
pulse input.
Relay delay
Defining the length of a pulse at the external mass counter pulse
output. Standard setting is 50 ms. The setting range is between
10 ms and 440 ms.
Operating time
The date and time of power failure are documented, providing in-
formation on power failure and service life.
