Cygnus 4 Operating Manual

10. Troubleshooting

The Gauge will not Switch On

• Are the batteries exhausted?
• Check the batteries are inserted correctly.

Difficulty obtaining a Reading

• Check that the Probe lead is properly connected to both Probe
and Gauge.
• Check the gauge is set for the probe connected.
• Check the condition of the lead, replace if necessary.
• Check the Probe and its membrane are properly assembled (if
a single element probe).
• On heavily corroded areas this is often a problem, try and
take measurements in adjacent areas of the same material.
• Check the Gauge and Probe together on a test block, if there
is still no reading the Gauge may require servicing.

If Readings are Erratic or Unstable

• Check that the Probe-lead is properly connected to both
Probe and Gauge.
• Check that the Probe and its membrane are correctly
assembled with sufficient couplant between the probe face
and membrane.
• Check the Probe Type is suitable for the probable minimum
thickness of the material being measured. Probe frequencies
too low cause doubling and tripling of the actual thickness.

Tips for Optimising Battery Life

• Couplant left on the probe face will stop the gauge entering
low power saving mode – so wipe couplant off the probe face
between measurement sessions.
• Turning down the backlight brightness will extend battery life.
• Turn Bluetooth off if you are not using it.
