1. The current check source under test.
2. The measured activity of the check source under test.
3. The anticipated actual activity of the check source based upon the initial calibration of
the source, corrected for decay.
4. The percent deviation of the measured activity from the anticipated activity. If the
deviation is greater than ±20%, the reading will be replaced by a dashed line – this
indicates an error condition (perhaps the wrong source is being measured).
Deviations greater than ±5% should be investigated. If the deviation is greater than
10%, contact Capintec’s only Authorized Service Center. Note that higher than
expected deviations may be within the limit of error, depending the accuracy of the
check source being used.
