Checking Parameters
Check the low alarm point setting by pressing the LOW ALARM button. The low
alarm point will be displayed as long as the button is pressed. The low alarm
point is in units of <units>. The low alarm point can be set from 0.1 <units> to
9999 <units>.
Check the high alarm point setting by pressing the HIGH ALARM button. The
high alarm point will be displayed as long as the button is pressed. The
highalarm point is in units of <units>. The high alarm point can be set from 0.1
<units> to 9999 <units>.
Check the calibration constant by pressing the CAL CONST button. The
calibration constant will be displayed as long as the button is pressed. The
calibration constant is in units of cpm (counts per minute) per <units>*. The
calibration constant can be set from 0.1 cpm/<units> to 9999 cpm/<units>.
Check the detector dead time correction by pressing down on the DEAD TIME
button. The dead time correction will be displayed as long as the button is
pressed. The dead time correction is in units of microseconds*. The dead time
correction can be set from 0.1 microseconds to 9999 microseconds.
Setting Alarm-Points
The LOW ALARM and HIGH ALARM points can only be changed while the
instrument is in calibration mode. Switch the top dipswitch CAL MODE (behind
the calibration cover) to the right to place the instrument into calibration mode.
Changing alarm points is done by holding down the corresponding parameter key
and pressing the up or down arrow buttons. Alarm points can be set in the range
of 0.1 to 9999. When an alarm point is changed, the instrument will sound an
audible beep to confirm the saving of the parameter, and will then return to
displaying the current radiation level.
Once the alarm point(s) is set, it is important to remember to switch
the CAL MODE switch back to the left. This action protects the
parameters from inadvertent changes.
