Calibration potentiometer
The calibration potentiometer allows to adjust the response of the DIAMENTOR E in
accordance with the ionization chamber in use. See also chapter 6.2.
If the test button (picture 3, 3) is pressed, a charged capacitor is connected to the amplifier in-
put. This results in a well defined number of counts. The status of the counter after this proce-
dure allows to estimate the response of the amplifier and makes an adaptation of the used
chamber possible. A detailed description of this subject is given in chapters 6 and 7 of this
manual.
If the high voltage is not sufficient or missing at all, the DIAMENTOR E shows a colon
between the second and third and between the third and fourth digit of the display. This also
happens immediately after switching on the DIAMENTOR E until the high voltage has reached
its final value.
