AW: [time-nuts] Cesium DOES Drift, not

2005-04-20 Thread Hubert v. Bonhorst
Just another idea Might be the Cs tube is just going to stabilize its magnetic field. Is there any possibility to degauss the tube, like with the 5061 high performance tube? This could be a very small drift/day. Hubert DB7ME -Ursprüngliche Nachricht- Von: [EMAIL PROTECTED] [mailto:[EMAIL

Hi Chuck: I have one of the many FTS4060/S24 units being sold on http://www.governmentliquidation.com. As far as I can tell these are stripped of every possible thing that could reduce the price and so I'm sure there's no built in degaussing capability. But I'm willing to wait out the problem

Hi Brooke, Well, the degausing can even be done using the coil that is used to set the offset. So, I wouldn't be so sure that you don't have a degaussing coil built in. -Chuck Brooke Clarke wrote: Hi Chuck: I have one of the many FTS4060/S24 units being sold on http://www.governmentliquidation.co

Hi Chuck: OK. I can set the 3 thumb wheel switches to 999, wait some, then to 000 wait some, then to 900 , 100, etc. etc. How many steps is reasonable and how long to wait? Thanks for that idea. Brooke Chuck Harris wrote: Hi Brooke, Well, the degausing can even be done using the coil that is use

Chuck, I have two 4060's, one like Brooke's and one regular production. Neither have degaussing connections inside or out and none of my 4060 manuals mention degaussing. My HP 5061's certainly have degaussing provisions. Take care, Had, K7MLR At 06:11 PM 4/20/2005, you wrote: Hi Brooke, Well, th

No, that isn't quite it! You disconnect the offset magnetic coil, and connect it to a variac with a series light bulb to limit the current. I cannot tell you what size bulb to use, or how much voltage, as I would have to make some educated guesses. Make the wrong guess, and B/O is possible. I re

Hi Chuck: If I had a schematic I'd give it a go, but without it, I'm not comfortable powering random wires. So it's back to waiting. Have Fun, Brooke Chuck Harris wrote: No, that isn't quite it! You disconnect the offset magnetic coil, and connect it to a variac with a series light bulb to limit
