Re: 7S12 with S-4 and S-53 troubleshooting

Re: 7L5 knob removal
On the right side: loosen two setscrews in the top and bottom rails just behind the front panel. One the left side: loosen a small setscrew on the top of the lower rail. It holds the left module pivot

SMA caps for sampling heads
My SD-26 heads came with shorting caps. And I need caps for my SD-22 heads. I'm wondering though if non-shorting caps would be more appropriate. The male pin rotating in the female sleeve seems as if

Re: 7L5 knob removal
Thanks Cliff. Before seeing your post, I figured out that the whole front comes off - the hard way. I started unscrewing everything front and back, and whole plug-in began to fall apart. It's pretty

Re: Scope-Mobile Cart Model 3 Disassemble
Hi All: If I remember... and it is the hex bolts/screws, in the pivot.. that are recessed... I used a ratchet and a socket, from a set of "deep sockets" to remove those. It's straight forward with

Re: 7L5 knob removal

Re: 7L5 knob removal
Ed, Be careful with those knobs. The switching (partly physical contacts and partly an optical encoder) is contained entirely inside the knobs themselves. Disassembly is not recommended unless they

Re: Tekmate 2402 rebuild and programming
What more would you like to know? The limitation with the 2402 is simply its age. The hardware is well made so, that aspect of the age is not a big issue. But DOS is a problem. MANY modern interfaces

Re: Tekmate 2402 rebuild and programming
