a transducer tip becomes too rough, concave, or otherwise non-flat, operation
may become erratic or impossible. Although some wear is normal in corrosion
gaging applications, severe wear will limit transducer life. A transducer
resurfacing procedure can be performed to improve performance of worn
transducers. Contact Olympus for details.
11.3 Error Messages
During the normal operation of the 27MG Ultrasonic Thickness Gage, certain special
error messages may be displayed. Usually these indicate a problem with the
operating procedure but some may indicate a physical problem with the gage itself.
Consult Olympus for further information.
11.4 Battery Problems
The bars on the batteries symbol show operating time remaining. If the 27MG
Ultrasonic Thickness Gage turns off immediately after it is turned on, or if it does not
turn on at all, then the battery is probably completely discharged. The batteries
should be replaced. If, after replacing the batteries, the unit still does not turn on,
there has probably been a component failure within the gage, which should be
serviced.
11.5 Setup (Do--) Problems
If the message Do ‑‑ will not go away when the [ZERO] key is pressed, make sure that
an Olympus transducer is plugged in. If so, the transducer may be defective. Try
another one if possible, or try a different cable. If no transducers will permit the
Do ‑‑
message to be removed, there is probably a problem in the pulser/receiver assembly
of the gage.
11.6 Measurement Problems Diagnostic
If measurements cannot be made and the MEAS and LOS flags are on, then there is
either a problem with the transducer or the pulser/receiver assembly, or there is not a
large enough echo being returned from the back wall of the material.
