Analyzer Does Not Power Up
Resolution(s):
• Check that the power is connected properly and you have the correct version for your power
supply
• Check that the power supply voltage is between 10V and 24VDC or 100V to 240VAC
• Verify that the power plug is seated fully in its socket all the way and no whiskers or wires are
shorting to each other or to the cover
Analyzer Reads Too Low
Resolution(s):
• Re-calibrate the Analyzer using air (see page 24)
• If the SPAN FACTOR is currently too high for adjustment, replace the oxygen sensor
• Calibrate with Span Gas. If the measurement readings continue to stay low, re-calibrate with
ambient air to verify (refer to pages 22 – 23)
Analyzer Reads Too High
Resolution(s):
• Leak test all external fittings. We recommend using SNOOP
®
(see page 19)
• Check that the gas flow rate is between 0.1 to 2.0 SCFH
• Increase flow rate from 1.0 to 2.0 SCFH while watching the oxygen reading. If it drops a few
ppm within 10 seconds, this is an indication that you have a leak somewhere between your
Analyzer sample gas connection and pipeline tap
• Confirm this by dropping the flow rate down to 0.5 SCFH while watching the oxygen reading to
confirm the reading rises a few ppm or more. The speed of how fast the oxygen reading
changes is indicative of how far the leak is located from the Analyzer. Snoop all fittings
carefully to find the leak point
