When the M or L Sinters or the Capillary probe are fitted, the ranges over which the
instrument may be calibrated are automatically changed to match the usable range of
the instrument. Appendix A contains a full list of the operating, calibration and alarm
ranges for all the inlet probes over a range of trace gas concentrations.
1.4 ARGON GAS SUPPLY
The instrument requires a supply of Argon that is at least 99.998% pure. This is
supplied with the instrument in a gas cylinder that conforms to BS 5045/3/B.
The gas cylinder should be filled to a pressure no greater than 200 bar (2900 PSIG)
maximum, and regularly checked for damage or fatigue and that the cylinder is still
within the validity of the test period indicated by the plastic collar on the stem of the
cylinder valve.
If an external gas supply is used the pressure supplied to the inlet port should not
exceed 4 bar (58 PSIG) maximum.
1.5 POWER SUPPLY
The instrument is supplied with an internal 12 Volt, gel electrolyte battery and a battery
charger. Both items are designed for use with the Q200 only. The manufacturer
accepts no responsibility if either item is operated with any equipment other than the
Q200. Information on spares may be found in Appendix D.
The battery charger must be run only from a mains supply that has a protective earth. It
is designed to be used on a flat surface next to the instrument and with adequate
clearance for ventilation. It should not be used whilst still located in the lid infill.
