(Note: If using the Slip-Ticket printer, please unplug from AC Power)

5. Connect the Beta Detector Cable to the connector at the rear of the CRC®-Ultra
Readout labeled “BETA”.

ENVIRONMENT REQUIREMENTS
The instrument should be located where the level of the background radiation is as low and
as constant as possible.

The instrument should be located where the temperature is stable within a range of +50°F to
+85°F (+10°C to +30°C) and the maximum relative humidity is 90% non-condensing to
warrant maximum reliability and accuracy.

4-2 SYSTEM SETUP July 16

CAPINTEC, INC. CRC®-ULTRA BETA DETECTOR

The instrument should be located where the barometric pressure is within a range of 27 – 31
inches of mercury (91 – 105 kilopascals).

CAUTION: If these environmental requirements are not followed, the instrument may
display erroneous readings.

GENERAL OPERATIONAL SETUP
There are several things that must be done before using the CRC®-Ultra Beta Detector for
the first time. The following briefly describes these steps:

• Select proper units: Ci or Bq. Although the system can be changed at any time, it is
recommended that the user set the proper units prior to using the unit to prevent
confusion. (Reference the CRC®-Ultra Owner’s Manual.)

• Enter Test Source Data: Test Sources (standard sources) are used for the Daily Test.
The Test Source can be Cs137 or Ba133. (Reference CHAPTER 5:BETA
DETECTOR INITIALIZATION; SECTION:TEST SOURCE DATA.

The following items should be performed before use if required:
• Assign USER Keys: The USER Keys (U1, U2, U3, U4, U5) are a quick way to select
a nuclide. A nuclide may be assigned to each key. (Reference CHAPTER 5:BETA
DETECTOR INITIALIZATION; SECTION:USER KEY ASSIGNMENT.)

• Adding a Nuclide: The CRC®-Ultra contains nuclide data (name, half-life, calibration
number) for over 80 nuclides. The user may add up to 10 nuclides: the name, half-life
and calibration number will be added for each one. (Reference the CRC®-Ultra
Owner’s Manual.)

ACCEPTANCE TESTING
The following tests should be performed prior to operational use of the unit.

Diagnostics Test
Reference CHAPTER 6:DIAGNOSTICS for instructions on how to perform this test.

Beta Detector Test
Reference CHAPTER 8:BETA DETECTOR TESTS for instructions on how to perform these
tests.

OPERATIONAL SUMMARY
While all users the CRC®-Ultra Beta Detector are strongly encouraged to read the manual,
we realize that there are some who would much rather jump right in. If you are one of those
people who say, “if all else fails, read the manual”, then reference Appendix I. These very
simplified instructions are intended to assist in getting you familiar with the basic operation of
the CRC®-Ultra Beta Detector. They are not intended to replace the detailed operating
directions in the main body of the manual.

WARNING
The General Operational Setup and Acceptance Testing sections above must be performed
before referring to Appendix I. The steps described omit several important tests which may
be required by your license and which are also required in order to achieve the full accuracy
of the system.

Resetting HV (High Voltage)
If you are having difficulty calibrating the Beta Detector, you may be instructed by Capintec
Support to reset the HV DAC to a particular value.

Note: Over time, the amplification characteristics of a photomultiplier tube change. If the
gain of the detector is not adjusted occasionally, the resolution of the detector
deteriorates significantly, making it difficult to identify isotopes correctly. Therefore, it
is important to check the gain of each detector at least once daily.

The RESET HV menu option allows the operator to manually adjust the gain in order to bring
the calibration of the detector back.

To perform this procedure, select RESET HV from Figure 5-3 Beta Detector Menu. Figure
