In addition to the standard magnetic transducers, Glue-On
transducers are available. The bolt end finish requirements are
the same for Glue-Ons as for the standard transducers. Glue
the transducer to the center of the bolt according to procedure.
Then place the probe so that the connector pin touches the
transducer. The rest of the procedure is identical to standard
magnetic transducers. See Appendix B for additional finish
and gluing information.
If the DS-instrument fails to find a signal from the bolt, this
error message will show. Please check if the cable is attached
to both the transducer and the instrument. Then check the
transducer to see if it is damaged. Apply more couplant and
verify the bolt information. Then hit
“RETRY”.
If you are using standard settings and the Ref Len is within
~4-5% of the physical measured length, the signal should be
acceptable for you to accept the reading by pressing the

button
You can also view the actual echo graph by pressing the
