Figure 9-2 Auto Calibrate Screen
To begin the automatic calibration, place the Cs137 rod source into the Well Counter and
then touch the Cal with Cs137 button.
Note: The recommended calibrated activity is in the 0.1-1.0 µCi range. The calibrated
activity must not be greater than 10.0 µCi (0.37 MBq).
The system will begin measuring the Cs137 rod source. As counting progresses, the live
spectra are shown. The system will count for as long as necessary until sufficient counts are
acquired for proper calibration.
To stop the measurement at any time, touch the ABORT CAL button. The collected data is
discarded. To re-start the process, touch the Cal with Cs137 button.
After the Cs137 calibration is completed, the results will be displayed as shown in Figure 9-3
Auto Calibrate Measurement Screen.
