MEASUREMENT ERRORS
During measurements, each screen gives you instructions on what to measure with the
probe or well and what information to input with the keyboard. If a measurement does not fall
within a certain expected range, the screen displays the following message:
MEASUREMENT ERROR
Press Any Key to Continue
The following are just a few examples of situations that could trigger this error message:
•
The Thyroid Uptake Protocol calls for Iodine-131, but the capsule you measure
contains Iodine-123.
•
The system asks for a measurement, but the sample is not in the Probe or Well.
•
The system is out of calibration causing the nuclide’s peak to appear outside of the
acceptable limits.
When you press any key, the screen goes back to the measurement you just performed so
you can correct the situation and repeat the measurement.
HIGH VOLTAGE ADJUSTMENT
The CAPTUS
®
600 has two analog coarse high voltage controls, which are independently set
for each detector (Probe and Well). These controls are used for the initial calibration and
manual re-calibration of the unit (if Autocalibration fails).
Adjustment clockwise of these two controls increases the voltage and counter clockwise
decreases the voltage.
Note: The setting of these controls should not be changed unless directed by a Capintec
Service Representative. Unauthorized adjustment of these two controls will invalidate
the calibration of the unit.
OFFSET VOLTAGE ADJUSTMENT
The CAPTUS
®
600 has two offset voltage controls, which are independently set for each
detector (Probe and Well). These controls are used for the initial calibration and manual re-
calibration of the unit (if Autocalibration fails).
Adjustment clockwise of these two controls increases the voltage and counter clockwise
decreases the voltage.
Note: The setting of these controls should not be changed unless directed by a Capintec
Service Representative. Unauthorized adjustment of these two controls will invalidate
the calibration of the unit.
