I'm doing some work with interfaces & doing some research on the test equipment & interfacing. I'm interested in both serial & parallel & the various types of test equipment, breakout boxes, line

Should have mentioned, these are Tek scopes.

I should have mentioned - if you use a simple LED deal, use a different color for each direction. The signal will be brief, and it's easier to discern which color flashed, than which of two same ones

When one object dumps charge to another with enough energy to make a spark, then you don't need any sophisticated instruments to tell the polarity. A couple of anti-parallel-connected LEDs will

Gold leaf is the standard for electroscopes because it can be beaten far thinner than other metals. It has been the standard for leaf electroscopes since British physicist Abrahm Bennett used it in

Hello, I and a friend changed out the batteries in my newly purchased 2712 today. The GPIB battery was totally dead on an unloaded meter... The other battery had 3.xx left. Both batteries were

Hmm... anything less rare? Anything I could take with me on the go? <bridgewaterma@...> wrote:

Aluminum foil is far too thick. An electroscope needs minimum mass, and that means leaf, not foil. The repulsive force in an electroscope is far too low for foil to work. For detecting direction of

Looking for a nice crack free front cover for the 465/475 scopes with DM44 or the 468. Thanks.

Hair on the wheels and some plastic of the wheels rubbing together generate lots of ES charge. Sort of like a van de graaff generator.

OK, so looking into it, a gold leaf electroscope will detect the presence of _a charge_, but what i want is to figure out the _sign_ of the current when an item is discharging into another item. I

Hi, I'm looking for a Keithley 2000 motherboard. Mine has some broken PCB tracks but I can't fix it. The PCB is multilayer. Thanks if anyone can help me. Mauirzio

Is anyone looking for a 575? I have two spares and need the room. PM if interested. I am in Kentucky. ThanksJeff Kruth

I just uploaded the SW, check the files section. Enjoy!

Hi all, I can aquire a second hand TG2000 ( Video Signal generator platform ) for 50 euro but the device was for a very longtime in storage and so the NVRAM backup battery is dead and all the signal

John, I have some single slot, one three slot, and a bunch of four slot TM500 frames. I also have a bunch of 500 series plugs - sold a few recently and got some left over ones. Let me know what you

I bought it. I miss the tm500 rack stuff. Hope I can buy something to put it in. Looking for a defective rack unit I can repair. Or a perfect one if possible. John

Yeah have a number of Keithley items (a couple 181, a couple 192, a few 197, a 228A, a 196, 150, 131, 130, 128), nothing current only working older pieces in my meter collection, and still have a 2000
