Betcha you will be pleasantly surprised. Fluke used to sell replacement battery packs, so there was no warranty. These did not damage anything, they simply loose the ability to take a charge of the decades. The problem is that you can not use the meter from AC, since the battery powered version has an inverter that needs the NiCads on the input side to operate. Look at the schematic of a model 8050, and read the manula where it warns you not to use that version with dead or missing battery packs. |

Otherwise, they would still have to support old vacuum tube based equipment that they built in 1948. They don't even list the manual for my Fluke 8050 meters. Luckily, several free archive sites have it in PDF. |

You just explained why my 8050a was acting rather oddly on AC. When I replaced the battery pack, it magically started working correctly. I was guessing a loose wire or component, but never suspected that anything required a working battery: <http://www.ebay.com/sch/i.html?_nkw=fluke+8050a+battery> I guess I should have read the manual. -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

You're welcome. I wish the Fluke 8920/8921/8922 true RMS meters (20 MHz upper limit) were as easy to repair and calibrate. I used one at Microdyne, so I bought one for myself a few years ago. Being able to set 0 dB where you want it, makes gain calculations easy. |

True enough, Fluke (for one) doesn't appear to mind that folks post their older technical manuals for obsolete equipment. I've hosted their manuals for almost two decades with no issues at all (Fluke 9010 and 9100 stuff). Data I/O is another, in fact most of the respectable technical tools company seem to implicitly support the dissemination of their older info to keep these devices running...

Sadly, it was the south end where the color-coding never took, not the north end. I bought them for the workbench, i really don't care that they are color coded like other adapters I have that are the wrong voltage. A cable connected to a 0-20V 3A HP 6253A power supply on the bench lets me power almost any DC powered device to see if it works, or to repair the ones that don't. No need to modify an existing supply, just to see if something works. :) |

They brag about their golf courses, amateur radio clubs and computer clubs, along with about 100 other private clubs. The place is crawling with old women looking for a man. I live about 10 miles away, and I hate to even go to the grocery store. When a woman calls you a youngster, and you are in your mid 60s, it's time to flee! |

Someday I will stop this tank > nonsense and just buy a small electric compressor. I have a portable compressor from Harbor Freight, and a 240 VAC 60 gallon industrial compressor and tank in my garage. If I cant reach something with 100 feet of air hose, I use the portable compressor. I like to clean the dust and crud out of equipment before it goes into the shop or into my house. This is the type of portable I have. I caught it on sale for $40. Then the 60 gallon compressor was given to me when a business moved and it already had a pair of three phase compressors with 120 gallon tanks. <http://www.harborfreight.com/1-3-hp-3-gallon-100-psi-oilless-air-compressor-97080.html> |

Terrell" <mike.terrell@earthlink.net>: Apr 03 12:31AM -0400 > activities my expectant folks were engaged in > back in the late '60s, and some choice names > my Dad coined me post-toddler-hood. I had health problems from an early age, so I spent a lot of time reading and experimenting since I couldn't play in any sport. I was born in the early '50s, when poorly trained doctors continued to prescribe DES to pregnant women in the false belief that it prevented miscarriages. It caused many health issues in the children, like my life long problem with infections. The last one required a trip to the hospital. I was also born with poor eyesight, and have worn glasses since elementary school. I now have to sit about 12 inches from a 24" monitor to see what I'm typing. :( I taught Boolean Algebra to myself, to be able to write software to track the C band birds. tHe program asked for your Latitude & Longitude, then it printed out a two page report with the Azimuth and Elevation for every bird you could see from your location. The program let you enter your name, so the report stated, Prepared by:----- ---- to make people think it came from an engineering service. The Commodore 64 didn't have several functions I needed, so I had to create them, as well. I always enjoyed a challenge, and often got what others had given up on. That is why I have seen so many odd conditions in equipment, in the last 55 years. I was a Nerd, long before it was cool. :) |

Doesn't look like dead pixels, more likely a logic corruption. The wrong letter, maybe just a weak bit in whatever holds the program memory. Start looking at the power supply (hey, it's a WEAK bit, could just be low battery). |

The wrong letter, maybe just >a weak bit in whatever holds the program memory. Start looking at the power supply >(hey, it's a WEAK bit, could just be low battery). I agree. Check the power supply voltage. My guess(tm) is that the display has a COB (chip on board) that has a broken wire bond and the display needs to be replaced. Just touching the blob of epoxy is sometimes enough to trash a wirebond and missing pixels cannot be produced by data errors between the synth and the display. 1601 displays are quite common and cheap, but not with EL backlighting. If you're going to replace it with an LED backlighting version, you'll need to: 1. Check the thickness of the display as they do vary and may not fit. 2. Disarm, disconnected, and possibly remove the EL high voltage power supply. 3. Find a way to power the backlighting. Some run on 5.0V, some bring out just the diodes and need a series resistor, and I ended up with one that wants 4.4VDC. I thought it was easy, but it took me several evenings to replace the display: <http://802.11junk.com/jeffl/Korg_DSS-1/> -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Yes, that looks like a ribbon-zebra-LCD contact problem. Carefully dismantling the assembly, cleaning the LCD and ribbon contacts and then getting it back together is risky, but then it isn't working now, so not that much to lose. Jon |

The fact that your router is reporting it means that your routers firewall is working. So no real panic. However, if it still is going on, probably easiest to acquire a different IP address from your ISP connection. This may be as simple as restarting your router, but obviously if you have a static / sticky address then this won't apply. -- Adrian C |
