6.5.8 Detectors response
You can use the “Detectors response” option to verify by means of the appropriate CRM the accuracy and
correctness of measurement for individual detectors and determine the response factor, see K1010-01-BT01.
 Hold the CRM closely to the detector.
 Set the measuring time (field on the right).
 Press the “Start” button to run the measurement procedure.
 After the measurement, the measured values are displayed on the screen for each detector
(indicated by a pictogram) and measuring channel (A, B). The values are given as total counts per
set measuring time.
 You are returned to the service menu by pressing the red arrow in the upper part of the screen.
The maximum number of pulses is 65535. Will be followed counting from zero.

The bit mask consists of eight binary digits - bits - which can have values (0 or 1). Each bit means a prescribed condition. Bits are
read from the right to the left (from the lowest to the highest one) and they are marked from 0 to 7 - for example 00000011, where bit
0 has the value of 1, bit 1 has the value of 1, bits 2 to 7 have the value of 0. The whole eight-bit recording is transferred from the
binary system to the hexadecimal system, namely 00000011 is written as 0x03. 0x is a prefix specifying a recording in the hexadecimal
system.

Errors of the detector can be removed by changing the setting of detectors via service SW. Settings shall be performed by the
manufacturer, service organization trained by the manufacturer, or the user's staff trained by the manufacturer.
