| jaugustine@verizon.net: Feb 11 07:12AM -0500 >>> Thank You in advance, John >>Back in 1995, I was able to order the manual from their parts department. It is Uniden part number SMBC855XLT (also known as part number 12A90-3AT200). It is 54 pages long, but the copy I purchased back then was missing pages 19 and 20. I contacted Uniden and they copied the missing pages and sent them to me. Back then the manual cost $16.00 plus $4.50 shipping from Uniden's parts department. >>If you can't get the manual from Uniden any longer, I could photocopy the manual, but it's got about ten 11 x 17 full sized schematics. It's a very comprehensive manual which covers everything and even has voltage measurements. Hi Ken, I am only interested in the schematic/s. I sent you an email, but never got a reply. Perhaps the email address was bogus, but the email did not "bounce". I offered you $10.00 in cash for a copy of the schematic. Another method would be if you have a DropBox account. Upload a scanned image of the schematic and include your address in a .ZIP file. If you have another idea, please post it here. If you want, I can post my REAL email address here, but you MUST let me know. Thanks in advance, John |
| localMIKE <run12345@eral.net>: Feb 10 12:46PM -0500 Hi. I am trying to determine the proper settings of the linkage of my barograph so that the pen moves the greatest distance up or down on the chart with as minimal movement of the aneroid disc as possible (in other words, the most sensitivity). I have placed some images here: https://imgur.com/a/HmJ9kcY The top image shows the configuration. A metal aneroid disc is attached to a rod that provides vertical displacement with changes in barometric pressure. The rod is then attached to a linkage system. The linkage can be adjusted to either magnify or demagnify the amplitude of the recording pen. The arrows in the second image show movement throughout the system. The furthest left arrow is movement of the aneroid disc, and the furthest right arrow shows the aneroid rod attached to an adjustable linkage that also moves vertically. The top of the adjustable linkage is attached to an adjustable screw with locknut. Movement of this screw one direction or the other helps form the axle for movement of the recording pen on the chart. The curved arrows show axle movement one way or the other depending on whether barometric pressure is rising or falling. Now my question is, what would the settings be for both the linkage and the screw so that the smallest change in the aneroid disc causes the largest change in the movement of the recording chart pen? Currently, I have the screw screwed all the way into the axle up to the locknut and I am utilizing the last hole in the linkage (third image down). However, I am not sure this is correct. Thanks in advance for your help. |
