Page 9: Preface
CAPTUS PREFACE Thank you for purchasing the CAPINTEC line of Thyroid Uptake Measurement Systems. Every effort has been made to insure that the information in this document is complete, accurate, and up-to-date. CAPINTEC assumes no responsibility for the results of errors beyond its control.
Page 10 Plug the unit into an outlet on a circuit different from that which the affected device is connected. If this fails to correct the problem, please contact Capintec’s Authorized Service Center. INSTALLATION Your system has been shipped from the factory pre-configured and fully tested. Installation consists of placing the components on the stand and securing them in place.
Page 11: Safety
® CAPINTEC, INC. CAPTUS CHAPTER 1 SAFETY ® These warnings and instructions for use form an integral part of the CAPTUS 600 and must therefore be kept available for consultation at all times. Precise compliance with the warnings and instructions is an essential condition for normal use, correct application and thus safety of patients and user.
Page 12: Warning And Caution Labels
® CAPINTEC, INC. CAPTUS WARNING AND CAUTION LABELS Located in the center section on both sides of the spring-arm of the floor stand is a warning label, (Figure 1-1), concerning the hazard of removing the collimator when the spring-arm is in the wrong position.
Page 13 ® CAPINTEC, INC. CAPTUS Figure 1-3 Located on the left side of the Isolation Transformer is a label (Figure 1-4), with two caution statements pertaining to the main power cord of the Isolation Transformer. The statement, READ INSTRUCTIONS CAREFULLY BEFORE CONNECTING TO OUTLET, directs the user to the owner’s manual before connecting the power.
Page 14 ® CAPINTEC, INC. CAPTUS Figure 1-5 ® Located on the connector guard on the back panel of the CAPTUS 600 Readout Unit is a label (Figure 1-6), with the caution statement pertaining to safety of the operator. This statement, DO NOT REMOVE CONNECTOR GUARD, is necessary because of the presence of high voltage on the connectors and on the inside of the Instrument.
Page 15: Cautions And Notes
However, there is no guarantee that interference will not occur in a particular installation. CAUTION If any printer other than the model supplied by Capintec is used, the safety of the unit may be compromised or Electromagnetic Interference (EMI) may be introduced into other devices ®...

® CAPINTEC, INC. CAPTUS CHAPTER 2 FUNCTIONAL & TECHNICAL DESCRIPTION GENERAL ® The CAPTUS 600 Thyroid Uptake / Well System is intended to be used by trained Nuclear Medicine Technologists for performing Thyroid Uptake, Thyroid Bioassay, Wipe Test, Blood Volume Test, Shillings Test and RBC Survival Test.
Page 18: Detector
® CAPINTEC, INC. CAPTUS Detector ® Your CAPTUS 600 system is equipped with a Probe (and possibly a Well), which consists of a NaI (Tl) (thallium-activated sodium iodide) crystal and photomultiplier tube detector assemblies. When a gamma or x-ray from a radioactive source reaches the NaI crystal, it collides with the electrons in the crystal matrix and transfers energy.
