Hi Atilio, Not on my unit, at least one zero should be lit. Without signal, the number of (zero) digits lit and decimal point position depends on the averaging setting (AVGS). Changing AVGS also

I’m sorry I can’t really help. But one thing is for sure, if you’re on any of the A Gate Time positions, you should definitely have a dot and some 0000.

Hello everyone, I am trying to repair a DC503A universal counter. I found a blown fuse on the line from which the 5Vdc is taken, I replaced it and the display turned on (only the first digit on the

For the Tek screw in question that takes a 1/16 Allen key, I have successfully drilled them out with a 3/16" bit without damage to the knob's threads. The screws are not 4-40 thread, but a 4-40 tap

An EZ-out sometimes works. In one case I had to shorten the EZ-out because it bottomed out before the reversing flutes could engage the ID of the setscrew. I also have a set of screw extractors (not

I have sometimes had to drill out the set screw. The damaged hex recess provides a guide for the drill bit. I use a left-hand drill in my vertical mill where I can easily reverse the rotation

These things rarely get seized; they are just really tight. If you can heat the screw with a very small soldering iron and let it cool (or shoot it with freeze spray), it might loosen up enough to get

I have had success using a torx driver and angling it to wedge it in, applying a high down force along with the angling force, and turning very slowly so that it doesn't slip and further turn out the

I take it back then, but I never had a 576 : (

clark, On that annoying tab, you can just cut the *fron**t* part off the extrusion, rather than the back. save the hammer for adjustments later... what's making me crazy is that I had a big stock box

Hi Jose, these knob in the 576 is a allen screw in " -----Mensaje original----- De: [email protected] [mailto:[email protected]] En nombre de Joseph Orgnero Enviado el: lunes, 1 de febrero de 2021

sometimes a piece of rubber glove over the key will assist in making a tighter fit. Renée

In my experience Tek uses only Torx screws on their equipment, trying to use Allen or Bristol wrenches is asking for trouble. Jose Orgnero VE7LBI

Dennis, On the 577, if I engage the offset, I only have to barely the rotodial thing to zero it. About 0.06 or so on the rotodial scale. Yes, I do believe something is amiss, as I would not expect a

This is a good question for TekScopes so I’m forwarding it on to the forum to see what they think Hi Sean, There shouldn’t be more than a few microamps of current for the zero step of a 2N3906.

Maybe a dab of epoxy at the tip of the wrench would come to the rescue (if you don't end up epoxying the screw in place)

Good advice for scavenging parts for a TM500 plugin. Take care with the 7k bottom extrusion. It has a tab to land the latch spring. 7k mainframe rails have a slot to accommodate the latching

Hi When I find in that situation I use a torx drive, the size that best fits, it has always worked for me -----Mensaje original----- De: [email protected] [mailto:[email protected]] En nombre de

One other thing comes to mind: With a hex key, you don't want to turn slowly. That allows the flats to push out and seize the threads ever tighter. To break a screw loose you want a sudden turn. Good

While I am sure there are many tips that others have, I found a thin hot soldering iron pressed into the iron screw socket head will sometimes add enough heat(expansion) to get things going. I have
