12. Programming the 6150AD3/4/5/6

You may program the 6150AD3/4/5/6 to meet your individual requirements. Programming is only

possible in the programming mode intended especially for this purpose. To enter this programming mode

you need to switch the instrument on while the function key and the signal key are pressed. In other

words, first press and hold down the function key and the signal key, then press and release the on/off

key. After that you may release the function and signal keys. This procedure has intentionally been

designed to be somewhat difficult, so that it will prevent users from entering programming mode by

chance or by mistake.
During programming mode the instrument does not monitor battery voltage. Therefore it will not enter

programming mode if battery voltage is below 5.5 volt, but will switch on normally instead.
The programming mode provides the following functions:

Programming an individual dose rate alarm threshold,
Programming an individual dose alarm threshold,
Programming the post-alarm increment (for dose alarm),
Enabling or disabling the non-volatile storage of the internal dose,
Resetting all programmable data to factory setting, and selecting the unit (Sv or R).

Use the function key to move from one function to the next, and use the signal key to select the function

to be executed. The flow chart in the appendix gives a quick reference which keys are to be used to

perform these functions.
All programmed data are saved in a non-volatile memory and therefore remain valid even after the

instrument has been switched off. The non-volatile memory is the same that stores the internal dose; data

retention time is at least ten years.
There are two ways to exit programming mode: Either you quit without saving data by pressing and

releasing the on/off key and thus switching the instrument off; or you save the indicated data by pressing

and holding down the on/off key and then pressing the function key. The instrument confirms the data

storage by means of a short sound (0.5 seconds) and then automatically switches itself off.
Note that you can only execute one function from the above list at a time. For example, if you wish to

program a dose alarm threshold and the post-alarm increment, you have to enter programming mode

twice and execute the appropriate function in each case.
The individual thresholds for dose rate and dose are kept separately for the internal tube and all probe

types. If you wish to program an alarm threshold for the internal tube, no probe may be connected before

the programming mode is entered. If you wish to program an alarm threshold for some probe type, a

probe of that type must be connected before the programming mode is entered. The upper left corner of

the LCD shows the probe type as in normal operation. Once you entered programming mode, it is no

longer possible to change the probe type since the instrument identifies the probe type only once at the

beginning of the programming mode. Therefore it has no effect to connect or disconnect a probe while in

programming mode; programming always refers to the detector that was active when entering

programming mode. For each of the seven detectors listed below, the instrument provides memory for

one dose rate and one dose alarm threshold, which makes a total of 14 thresholds:
