5200 Multi Purpose and 5200 Multi Purpose HF Gas Analysers
05230001A / Revision 938
6.2 Taking sample readings
1. If necessary, calibrate the Multi Purpose: see Section 6.1.
2. Ensure that the Measurement screen is displayed: see Section 4.
3. Use the quick-connect fitting supplied to connect the sample gas supply to the
sample gas inlet on the front of the Multi Purpose (see Figure 1).
4. If your Multi Purpose has a sample pump, start the sample pump: see
Section 5.3.5.
5. Wait until the measurement shown on the screen has stabilised, then take note
of the reading.
6. If your Multi Purpose has a sample pump and you have selected manual pump
operation, stop the sample pump: see Section 5.3.5.
7. Turn off the sample gas supply, or disconnect it from the sample gas inlet on the
front of the Multi Purpose.
Repeat Steps 3 to 7 as necessary, for different gas samples to be measured.
+
Depending on how you have configured the measurement alarms, and on
how you connect the sample gases to the Multi Purpose, a measurement
alarm may occur when you change sample gases as described below.
+
Unless your sample gases are known to be dry, you must connect the drying
tube (supplied with the Multi Purpose) to the sample gas inlet on the Multi
Purpose, and then connect your sample gas supply to the drying tube.
+
The procedure in this section is for a Multi Purpose without an optional
flowmeter, sample conditioning panel or gas probe. If your Multi Purpose has
one or more of these options, refer to the appropriate Appendix A6,
Appendix A7 or Appendix A8 for additional information on sampling.
