Mystery part Type 576 Curve tracer.
|
All:
Now that I have got my 576 working reliably, I was going to start calibration and I found a pair of what appear to be silicone washers laying in the bottom of the unit. I have no idea where these are supposed to go. The color is a translucent and slightly off white. The parts are very soft and pliable. The appearance is like that of silicone or a similar rubber like material. The dimensions are 22mm OD x 8mm ID x 2.25mm H (or thick). There is no appearance of any adhesive residue on these parts. These were laying at the bottom of the unit and had a layer of dust on top. Photo is here: /g/TekScopes/album?id=247763 This unit is a very Low Serial number unit B0100169 and this is the one that I used as my "Test Mule" for the HV transformer project, it is in pristine condition inside. The unit seems to work just fine (other than needing a calibration) and I have not done anything else to disturb the internal parts of the unit, other than the HV Supplu cover and board. I do not believe that I dislodged these, since they appear to have been laying in the bottom of the unit for quite some time. Any ideas what these might be or where they need to be installed? Thanks in advance. . -- Michael Lynch Dardanelle, Arkansas |
