Nothing you do subsequently will prevent the shut-off, >except recycling the power before it happens." I like my old Fluke. Mechanical power switch, but then again it runs off the mains, not a battery. You would think they have the technology to detect if there is something connected to the probes but the fact is that new engineers don't know shit and even if they do have never serviced anything in their life or even done any product testing. Now CROs on the other hand might benefit from something that will at least turn down the beam current in the absence of a signal. That would save it from screen burn. Some of them had writing speed enhancers so they already had most of the circuitry. But they don't make CROs anymore, much to my dismay. I prefer them alot. The LCD scopes might have the bandwidth and features but if they only update the display ten times a second they would be useless for much servicing, I need to see it NOW when something is going into shutdown or whatever. Bunch of junk as far as I am concerned. Well, OK I never used a really high end one but I ain't spending $400,000 for a machine that is used to fix the cheap shit I fix and is susceptible to viruses and needs software updates. Fuck all that. Anyway, all you on here might enjoy a look once in a while at a website called "Made By Monkeys" which, while updated infrequently, has stories about shitty designs and engineering gaffs and the like. There are a few interesting posts there, and I have not gone all that far back in their archives, so there might be more interesting stuff. |

I have about 8 of them, and none do that. You just turn the range switch.

You just turn the range switch. That's no less annoying. >I have a lot of them that don't do it either, but at least one 4.5 >digit hand-held and another multifuction 'tweezer' measurement unit >do-do it. Ain't nuthin' you can do abahd 't. Every one I've had does it. The range switch thing works, for small values of "works". 'cept as you hint at, those that have no range switch. |

My Tek ones allow you to disable it by holding down a button as you turn the meter on. I think the Fluke 87 does too. (I bought mine in 1988.)

I think the Fluke 87 does too. (I bought mine in 1988.) I don't know all the model numbers, but the Flukes I have will allow you to keep them on by pressing a button when turned on. |
| makolber@yahoo.com: Sep 13 07:50AM -0700 tiny wire is inherently unreliable adding a transformer and using 24V valves is a good idea. or use 120V valves and wire the 2 in series instead of parallel? m |
