Here is a breakdown on each of the menu options:
• Background Rate – This determines the dose rate level when there is no source
present. This is used to create an environment with a constant dose rate level.
• Rate Alarm – This Alarm determines the dose rate level to which any great increase
in dose rate will trigger an audio alarm. This alarm will have a frequency of 1 tone
every second.
• Chirp Dose – An audible beep every time set dose is accumulated.
• Dose Alarm: The first dose alarm. The instrument will alarm once the accumulated
dose reaches this threshold.
• Final Dose Alarm: The final dose alarm. The instrument will alarm once the
accumulated dose reaches this threshold.
• Sound – This determines the initial audio state of the device upon turning on.
• Network – This determines the network type of this instrument. There are two states:
Master and Slave. The Master instrument will control the addition of any new
instruments into the Radiation simulation network. There must always be one Master
instrument switched on to control this network. The Slave units do not have this
controlling function, but will join any radiation simulation networks upon turning on.
(This radiation network technology is common to all SAFE-Series instruments.) After
initial configuration, the devices will remember the set up and use this the next time they
are turned on until such time as the set up is manually changed.
The Network Status of the instrument is shown upon boot
up as shown:
Audible Alarms:
The Dosimeter has 3 audible alarms.
Chirp Dose – The Dosimeter will give one single short beep for each incremental amount of
dose received ie Set at 50nSv will beep at the first 50, then after a further 50 etc.
Rate Alarm – The Dosimeter will give an intermittent alarm beep when the rate alarm
threshold is exceeded. This Alarm will have an audible intermittent sound until acknowledged
by pressing the button.
