4.1.2 Dark Count Rate Measurement
• Check the detector output by means of your end-user software (e.g. GUI software) after ramping to the
operation voltage (the use of the rate meter where available is recommended).
• The dark count rate without any source should be as given in the specification sheet.
• Accumulate the dark counts for several minutes (e.g. 15 minutes). The DLD image should appear
homogeneous and sharply bounded. See
for an example (your specific DLD image can differ
in size, shape and segmentation).

4.1.3 Standard DLD Operation
• After finishing the dark count rate measurement with a satisfying result, you may now start carefully
with an electron or light source observing the detector output.
Keep in mind the description about the important operation details in
.
Note
Turn off the high voltage, close the software and turn off the TDC before performing any
changes of the cabling.
