Q200 User Manual WARNING AND CAUTIONS
200120/Revision 10 1-1
1.0WARNINGAND 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.

Q200 User Manual WARNING AND CAUTIONS
1-2 200120/Revision 10
1.3.1 CHANGING FROM CAPILLARY MODE TO SINTER MODE.
CAUTION: Before changing the hand unit probe ensure that the hand unit
detector block is cool.
1. Remove the capillary probe nozzle from the nozzle cone by pulling the probe
nozzle out of the nozzle cone. Ensure that the capillary probe nozzle is pulled
out of the nozzle cone in the line of the hand unit to avoid bending the capillary
probe needle.
2. Unscrew the nozzle cone from the hand unit.
3. Unscrew the capillary needle probe and its housing from the front face of the
detector assembly and store in a clean dry place. Note that the small knurled
cap on the housing retains the capillary needle probe in the housing.
Unscrewing the housing using the larger knurled flange adjacent to the front
face of the detector assembly will allow the needle probe and its housing to be
removed from the detector assembly as a single entity.
4. Locate the required sinter and inspect the seal around the periphery of the
sinter to ensure that it is not damaged. Damage to the seal will compromise the
performance of the instrument by allowing an excessive amount of air to enter
the detector. Appendix D contains details of replacement seals that can be
fitted to the sinter. Fit the sinter into the front of the detector assembly. Use a
broad flat bladed screwdriver to tighten the sinter into the detector assembly.
5. Screw the nozzle cone back into place on the hand unit.
6. Push the sinter probe nozzle firmly into the nozzle cone.
7. Re-configure the instrument as outlined in 1.3.3.
8. Perform a cleaning cycle of at least one hour.
1.3.2 CHANGING FROM SINTER MODE TO CAPILLARY MODE.
CAUTION: Before changing the hand unit probe ensure that the hand unit
detector block is cool.
1. Unscrew the nozzle cone from the hand unit.
2. Using a broad bladed screwdriver, unscrew the sinter assembly from the front
face of the detector assembly and store in a clean dry place.
3. Remove the sinter probe nozzle from the nozzle cone.
4. Locate the capillary needle probe and it’s housing and inspect the seal around
the periphery of the housing to ensure that it is not damaged. Damage to the
seal will compromise the performance of the instrument by allowing an
excessive amount of air to enter the detector. Appendix D contains details of
replacement seals that can be fitted to the housing. Screw the capillary needle
probe and its housing into the front face of the detector assembly until finger
tight.
5. Screw the nozzle cone back into place on the hand unit.

Q200 User Manual INTRODUCTION
200120/Revision 10 2-1
2.0INTRODUCTION
The Q200 is a high sensitivity leak detector used to locate and quantify leaks with
electron capturing trace gases. The instrument may be used in a variety of industrial
and scientific applications and environments. It is lightweight and robust and comprises
a hand unit, control console, rechargeable battery and Argon gas cylinder, contained
within a case for complete portability. Facilities are built in to allow the instrument to be
operated using external gas and power supplies.
The instrument is microprocessor based, using a Vacuum Fluorescent Display (VFD) to
provide a rapid and accurate readout of leak rates. The built-in memory is capable of
storing up to one hundred separate leak rate readings, which can be output to a printer
via the built in RS232 interface connector.
The detection principle uses a single Electron Capture Detector (ECD), utilising a low
power radioactive source contained within the hand unit. To measure for leaks, the
component under test is filled with a trace gas until there is a slightly higher pressure
than ambient within the component. This condition will cause the trace gas to leak
through any cracks, holes or porous areas within the component. Leaking trace gas will
then be detected and quantified by the Q200.
Each instrument is factory configured for a specific trace gas and measurement unit.
By default the instrument is configured for SF6although configuration for other gases is
available on special order.
This manual is written specifically for an instrument configured to SF6, H Sinter
and ml/sec. Instruments configured for other gases, sinters and units will
perform identically except that some display formats are different, and the range
and step sizes for calibration and alarm levels are different. The user may
convert between leak rates in different units by referring to Appendix J.
