7. Place the Inspector+ or the Inspector+ EXP probe at a distance from the
source that corresponds to a 5 mR/hr field with the detector window facing
the source.
8. Repeat Steps 2 - 5.
9. Calculate the average of the readings and record.
a) If the average is ± 10% of 5 mR/hr, the calibration procedure is complete.
b) If the average is not ± 10% of 5 mR/hr, go to Step 10.
10. Turn off the AUDIO in order to hear the count down timer sound.
11. Turn off the Inspector+. Hold down the "-" button on the end panel and turn
on the Inspector+. The display shows CAL, and the Inspector+ counts down
for 15 seconds, chirping each second. This delay gives you a chance to
move out of the field and then expose the source. At the end of the 15
seconds, the Inspector+ beeps.
12. The Inspector+ now collects data for 30 seconds, chirping every 2 seconds,
with CAL and the hourglass icon flashing. At the end of the 30 seconds, it
beeps. The display shows CAL and SET is flashing.
13. Close the source.
14. Press the "+" and "-" buttons on the Inspector+ to adjust the reading to what
it should be.
15. When the reading is correct, press the Set button. The new calibration factor
is displayed for several seconds, then the Inspector+ beeps and resumes
normal operation.
16. Record the new calibration factor.
17. Place the Inspector+ or the Inspector+ EXP probe at a distance from the
source that corresponds to a 5 mR/hr field with the detector window facing
the source.
18. Repeat Steps 2 - 5.
19. Calculate the average of the readings and record.|
a) If the average is ± 10% of 5 mR/hr, the calibration procedure is complete.
b) If the average is not ± 10% of 5 mR/hr, repeat steps 11 - 16 and go to
step 20.
20. Calculate the average of the calibration factor for 50 mR/hr and the
calibration factor for 5 mR/hr.
