At the beginning of programming, the most significant digit of the first window is selected and thus
flashes. You may adjust that digit using the signal key. Once adjusted, select the next digit by pressing
the function key. If the most significant digit is zero, the next digit will be the most significant digit of the
next window. In other words, setting the most significant digit to zero and selecting the next digit will
also move to the next window. If the most significant digit is non-zero, or if you already are in the last
window, pressing the function key will move around the three digits of the current window. It is not
possible to go back to a previous window; in that case you need to quit programming mode and restart
If you wish to clear (disable) the threshold, set it to zero. For this purpose all three visible digits have to
be zero irrespective of the window you are currently in.
In order to store the threshold, press and hold down the on/off key, and then press the function key.
The factory setting for individual dose rate alarm thresholds is »OFF« (disabled).
Individual Dose Alarm Threshold
This function allows to view and modify the individual dose alarm threshold. If you do not wish to
modify that threshold, press the function key to move to the next programming function (see next
If you wish to modify the threshold, press the signal key. Now you get access to the digits of the threshold
in the same way as for the dose rate alarm threshold (see previous section). The least significant digit of
the dose rate alarm threshold is 1 µSv.
The factory setting for individual dose alarm thresholds is »OFF« (disabled).
Post-alarm Increment for Dose Alarm
This function allows to view and modify the post-alarm increment. The current setting is displayed as
(= post-alarm in steps of 2%, factory setting),
(= post-alarm in steps of 5%),
(= post-alarm in steps of 10%),
The first two digits (2/5/10/no) flash to indicate that they are subject to modification. If you wish to
modify the setting, press the signal key repeatedly until the requested value appears. Store the setting by
pressing and holding down the on/off key and then pressing the function key.
If you do not wish to modify the setting, press the function key to move to the next programming function
The post-alarm increment applies to the dose alarms of the internal tube and all probes.
