"I agree with Maurice. You'll need to send it in to a Leica dealer for service. 'Weak signal; error code 1292' indicates either no target or a Cal motor problem. I recently had a similar issue with my TPS800 series.
Your drawing nicely illustrates the point some of us were trying to make: The sighted object never moves.... it's the compass circle relative to the variations of magnetic north that rotates.
I hope it puts this…"
"For me it always helps to use visuals; so I got out a full circle, 360 degree, see-through protractor. I think we all agree that the True azimuth in 1880 was 276 - 15. It helps to lay it out on a pad of paper and mark the fixed…"
"OK here goes Billy.
I reduced the scan resolution and got the pdf file down to a manageable size.
So here is that article by Dr. David Knowles from 1986. Back in the day, I found it to be an excellent and very helpful article…"

This may have already been emphasized in the previous threads regarding Celestial Observations; but I wanted to also remind all of us about the 'extreme' importance of recording accurate time when taking…"
"Greetings Billy. Yes this prism mounts on the front of the scope. As you can see in the first image I posted, the darkener/prism section is 'hinged' so you can flip it off for sighting your backsight point. When sighting the sun with…"

Introduction to other Surveyors. One or more sentence Bio about your Relationship with Surveying
My early background in Surveying began in the 70's after completing a BA in English and then an Assoc. Degree in Land Surveying. My first land surveying work was very rewarding and interesting.It primarily involved extensive title search and retracing boundary evidence of large land tracks in the southern Adirondacks. These were still the days of theodolite and chain measurements for the most part. Then 2 years in the Peace Corps as an ag. extension agent in Sierra Leone doing primarily rice paddy development and Survey/Mapping support for paddy irrigation systems. After Peace Corps I went out to the west coast (CA)to work for the US Forest Service as a Transportation Planner, Logging Systems Specialist, wildland fire fighter, and eventually back into Cadastral Surveying with the USFS and BLM. My work as Party Chief of a Cadastral Survey crew involved retracing suspect and/or fraudulent 1880's GLO surveys in remote Northern CA mountains. After 35 years with the USFS, I'm now back East(PA) winding down my FS career and planning/building my next career as a private practice Licensed Professional Surveyor.

Hey, Bennie is that a Honda Trail 50, sure looks like one.I loved mine had to move on to three and four wheelers. yamaha made a bw big wheel that was a bike with All terrain tires they only made them 2 years, i love mine in the woods it was a step to make a 2 wheel machine approved for forrest trails,because of low pressure tires, i had a time getting mine approved. No it must have 3 or 4 wheels was all i heard. The head Ranger finally gave in an issued me a permit.
YEP, MY SYSTEMS ARE BETTER THAN WHAT THEY ARE DOING TO DAY. YOU CAN NOT FIND ANY OF THESE YOUNG GUYS WHO EVEN OWN A CALCULATOR, THEY WANT TO DO EVERYTHING ON COMPUTERS, AND WHATS UP WITH NOT USING A DATA COLLECTOR, NO WAY A TOTAL STATION FASTER, THEY DO NOT WANT TO LEARN ANY MATH, HOW ARE THEY TAKEN A TEST I TRIED TO GET THEM INTERESTED IN EMULATORS NO LUCK, TDS STILL MAKES GOOD STUFF YOU KNOW THERE PART OF TRIMBLE NOW. I AM LEARNING THE HP PRIME PROGRAMMING NOW I THINK IT'S REAL COOL. DID YOU SEE ALL THE PROGRAMS I GAVE ON THE HP 35, IT IS USE MORE THAN ANY OTHER CALCULATOR TO TAKE A SURVEY EXAM. I ALSO SHOWED HOW TO USE IT MANUALLY TO SURVEY WITH AND HOW TO USE LINEAR REGRESSION ON IT, AND TO USE INDIRECTLY ADRESSING MEMORY. WHAT OTHER CALCULATOR CAN DO ALL OF THIS. AND WHY NO COLLECTORS, ME A DATA COLLECTOR ANY DAY . THANKS YOUR INTEREST BENNIE PS I DID SOME WORK WITH THE FORREST SERVICE TOO. AND IT SHOWED IN MY TREE SURVEYS. THEY CALLED ME TREE MAN, GOOD TO MET YOU.
