Cable cross-section
The cable cross-section is dependent on the cable glands used.
Wire cross-section for spring-type
terminals

Scintillators
High voltage generation
Voltage range of control 300V to 1300V
(error message below 300V and above 1300V)
Voltage range external setting 300V to 1300V
Sensitivity changes due to temperature variation or due to ageing
are automatically compensated for by an automatic high voltage
control.
