1.0 WARNING AND CAUTIONS
This section explains the warnings and cautions that should be observed when
installing or using the Q200.
1.1
HAND UNIT DETECTOR
The detector operates at elevated temperatures; the user should proceed with caution
whenever the hand unit nozzle is removed.
The detector contains a radioactive source that should never be tampered with. The
detector contained within the hand unit has the following characteristics:
Nuclide Nickel
63
Radiation Beta rays
Content 370 MBq
Beta energy 60 keV Max
Range in air 50 mm approximately
Half-life 100 years
The primary Beta rays are completely contained within the detector cell and provide no
hazard to the user during normal operation. National Regulations relating to the control
of radioactive sources vary from country to country. It is a requirement in some
countries, and a practice that we would recommend that a competent person be
appointed to be responsible for the instrument. Their duties would be to ensure proper
care is taken of the instrument and all users are instructed in the use of the instrument
and not to attempt access to the radioactive sources. In the event of damage or loss
occurring, there may be a requirement to notify the competent authority.
Specific instructions may accompany this manual describing any further national
regulations governing the use, storage and transportation of equipment containing
radioactive sources. In the UK the radioactive source must be checked at least every
24 months for leakage. The supplier of the equipment can provide this service.
1.2 SINTER
Periodically the user should remove the nozzle and inspect the sinter, see Appendix I
for more information. A new sinter should be fitted if the current sinter is discoloured
indicating deposits of contaminants exist on its surface. Progressive blockage of the
sinter can also be observed by progressive reduction in detector response to standard
leaks or increasing calibration factors when performing calibration sequences.
1.3 CONFIGURING THE Q200
The Q200 has been factory configured to match your requirements with respect to
language option, the type of trace gas to be used, probe type and the displayed units.
If a configuration change is required, it can be performed as detailed below.
