2. Plug the cable into the upper jack.
3. Use the following table to check the Radalert 100’s accuracy.
The table shows appropriate pulse generator count rates to
calibrate for Cs-137. If the accuracy is not within desired
limits, follow steps 4-7. Note that the Radalert 100
automatically compensates for lost counts due to GM tube
dead time. Thus, the display reading in CPM mode does not
equal the input frequency. You can display uncompensated
counts in CPM mode by continuously holding down the –
button; the reading now corresponds to the input frequency.
4. Start with the Radalert 100 turned off and the Mode switch set
to mR/hr. Hold down the – button on the end panel while
you turn the On/Off/Audio switch to On . (Don’t use the
Audio setting.)
The display shows CAL , and the Radalert 100 counts down
for 15 seconds, chirping each second. At the end of the 15
seconds, the Radalert 100 beeps several times.
5. The Radalert 100 collects data for 60 seconds, beeping as it
does so, with CAL and the hourglass indicator flashing. At the
end of the 60 seconds, it beeps several times. The display
shows
CAL and SET .
