Was Workstation 4 (even unlicensed) ever installed on this PC. Maybe a lingering newer driver was installed by Windows. Just speculating here. No free time to give it a try myself.

your post is from a long time ago. but I wanted to let you know, Just found out I am able to use WS 3.5.4 and Huntron in window 10. I think it would work for windows 7 too, only if I remembered what I did. but it really works on my windows 10 System. the only thing, "help" does not work. when help is selected in any window it opens the web browser on  a Microsoft page stating Help is not supported... . WS 3.5.4 functionally works with my ProTrack, hand probing and scanning both work on my windows 10 system. :D  ;D  :P

Good job! The 2700 was our first Tracker with a LCD and was not very good as far as display speed. If you are used to CRT Trackers than the 2700 is less than stellar.

Alrighty then....

Hey Dummy, if the fuses are blown replace them first, DoH!

It appears to be working now. I ran it through the diagnostic test procedure and it runs all the way through without issue and using the Huntron ASA test board I am getting what I would expect to be good signals. I have not yet compared with our 2 workhorse 2000's.

I do have yet another question, the signal line on the display is 'pulsing', is this normal behavior for the 2700? (We bought this machine used and it has never been used since it was not working so we do not know what the expected behavior is supposed to be.)

Personally I like the green phosphorous displays, no flicker, no pixelation, no pulsing. Just good clean signals. We also have VI Curve Tracer setup on an old Tektronix and it is bright, instant response and super clean signaling.

I want to thank everyone who has helped in this thread!

Quote from: ramiroelliot on October 13, 2024, 07:51:01 PMWondering if anyone has experience with the Huntron 2000 tracker , from what I understand the lowest ac output is 10v , Read a few posts that say this is too high to test many transistors without damage . Was wondering if it would be possible to lower the minimum voltage to 200-400mv by modifying the unit . any input welcome .. Roger

We have been using the Huntron 2000's for 30+ years without any issues. We mostly test military avionics boards and have never damaged any components. Its not the voltage that will kill a component it is the Amperage and the Huntron puts out an extremely low amperage signal so as not to harm any components.

We currently have two Huntron 2000's in daily operation that keep on trucking like battle hardened front line  soldiers.

I think you might be wise to digest the entire users manual that is available freely online. If you need a copy I can gladly send you a pdf copy. You might want to study chapter 9 as it deals with BJT's and it is possible to upset the Hfe rating of a BJT during testing. These are temporary changes for the most part and can mostly be avoided by testing in the Med2 to High range. Take note on page 9.2

Other then that I don't think your going to damage anything, if it where a issue we would certainly be aware of it by now.

Congrats on the new acquisition, it will serve you well.

I would not modify it in anyway, you more likely to damage it then successfully modify it.

Hello Fetron,

Thanks for the help on this situation. I have ordered all the parts you have suggested might be faulty, in addition to several new fuses. I think first step will be to pop in new fuses and make sure I aint chasing my tail. If they pop again I am just going to replace all the parts in the circuit you suggested and go from there.

Most likely update mid week.

Thanks Again!

Welcome to the Huntron Users Forum, Roger.
I suppose anything can be modified but voltages in a Tracker 2000 are set by the signal transformer so modding it could be more work than it is worth. If you need lower voltages, the Tracker 200 (needs an oscope) or Tracker 2500 had low voltage ranges. Of course, you could look at a new Tracker 2800!  ;D

Hello!

You wrote that +28 / -28V you only measured +25V and -25V.
Switch on Huntron 2700.
You should try to increase the mains voltage (from 110V slowly to 120V) with a variac transformer.
Meanwhile, measure +28V / -28V. As soon as it reaches a good value, stop increasing the mains voltage.

Huntron 2700, set 20V / 2kHz / 100 kOhm range
Measure the points marked with a question mark with an oscilloscope.

Measure +28V / -28V and +15V / -15V with an oscilloscope.

Next: Switch off Huntron 2700.
Measure the capacitors, diodes and resistors shown in the drawing.
If these are good, AR14, Q1, Q2, AR7, AR12 may be faulty.
