It is not normal for the plate to retain an image after passing through the processor. You may have to get the light in the internal of the processor checked. The plates should retain sensitivity for approximately 10,000 exposures.
For the price we pay for these units, I would call your...
I recently ran a test for a client. I calibrated to S/S and took readings on a C/S pipe. Then calibrated to C/S and took readings at the same locations. My thickness readings varied .030" on same. That's dealing with materials 3/8" to .5" thick.

Yes we are working on that, just was wondering why with a material name S/S we achieved a more accurate reading calibrated to C/S. I figured it was due to the carbon content, but thanks for clearing that up.

An UT thickness inspection crew took thickness readings on a A-182 F-53 super duplex 8" reducer. At the time of inspection, the material wasn't known. The crew calibrated to S/S and achieved a reading of .138". I knew that wasn't correct. I had them calibrate to C/S due to the fact of the...
We use hammers these days more to clean loose scale and for a general soundness check on different items, i.e., trays, other internal equipment, valves, flanges. Not used to determine a thickness of metal. But all inspectors should use their hammer when testing nuts and bolts where a tap would...
