Troubleshooting Troubleshooting
Some common reports received by our Service Department along
with possible causes. Most conditions however can be cleared
with a Reset (pg. 13).
#2 #1
Coating
Substrate
Probe
Couplant
Measurement of dense (hard) coatings.
A significant echo occurs at the probe/coating interface. The
relative strength of this echo compared to the coating/substrate
echo requires that Lo Value be increased.
Measurement of total thickness in multi-layer coating
applications.
Multiple coating/coating/substrate interfaces may generate
several echoes. The user may need to adjust the Gage’s
Set Range (pg. 11) to ignore echoes from coating/coating
interfaces.
Gage does not turn on
Make sure the + and - battery terminals are positioned properly
and that fresh batteries are being used.
Gage powers up but fails to stay on
Replace batteries with fresh batteries. If problem persists return
Gage for service.
Gage readings are much lower than expected
Gage may be measuring surface roughness. Raise the value of
Lo Range (See pg. 11).
