5.4.5 Show and Change External Dose Rate Alarm /
Count Rate Alarm Level (XT.RAL/XT.CRA)
The external alarm is dependent of the connected detector. For
dose rate detectors the alarm is dose rate alarm (XT.RAL) and
for count rate detectors the alarm is count rate alarm (XT.CRA).
There are 8 different levels for dose rate alarm:
 Disabled, 10, 50, 100, 500, 1 000, 5 000, 10 000 or 50 000
µSv/h or mrem/h.
The user may select any one of these to be the active alarm
threshold level.
Note: All these dose rate alarm threshold levels can be changed and stored
into the instrument’s internal memory with the CSW-31 software.
To see the current dose rate alarm threshold level:
 Activate the menu (Short [Ξ]) and scroll (Short [Ξ]’s) until
display changes to XT.RAL
 The current dose rate alarm threshold value is displayed on
right side of the display.
