Out of Production Hardware / Re: ProTrack Scanner failing L...
Last post by admin - February 21, 2023, 03:31:32 PMWe should clarify some terminology here. Loop Calc is a process run on the ProTrack and is not a diagnostic for the Scanner. Clicking the Loop Calc button will cause all of the diagnostics to be run (including the Scanner test if one is connected) prior to the Loop Calc process. This is done to make sure the Tracker is working properly before running the Loop Calc. Since the Scanner test fails the diagnostics never gets to the point of running the actual Loop Calc process. You can bypass the diagnostics and go straight to the Loop Calc process by using the right-click, left-click trick described earlier in this thread. The title of this thread should probably be changed to "ProTrack Scanner is failing the Scanner Test".
If you are going to be using the Scanner then of course you should fix the problem. One thought would be to check the connections from the BNC connectors to the ProTrack main PCB. Maybe they are slightly corroded adding some resistance to the signal line.

Try to run the diagnostic function for Huntron workstation software. The hardware test useful function.

Last post by Paula Silva - February 13, 2023, 06:26:04 AMHi, everyone. Unfortunately I have to realize my tracker is broken, each of the three firmware versions I got brick it when trying to save some parameters (probably the culprit is one of those RAMs Fetron mentioned previously). Gonna order them both, replace one at a time and then let you all know the outcome.
Anyway, thank you all for your kind support!

Current Software - Huntron Workstation 4.X / Re: Shorts test.
Last post by jvthorsley - February 09, 2023, 08:51:37 AMHi Curtis
Yes I am referring to the Shorts Test.
The shorts test is looking for anything up to 5 Ohms.
Possible to call an open as anything more than 10 K Ohm?
But adjustable as the Shorts Test setting.
Probably not enough demand for this!
As said the 47 K Ohm Resistors give a 45 Deg. trace so anything previously not recorded north of the trace is a short, and anything south of the trace is an open circuit.
The attached photos show the more severe kind of damage that can occur at 12 V.D.C. with lots of available current!!

Current Software - Huntron Workstation 4.X / Re: Shorts test.
Last post by admin - February 09, 2023, 08:27:25 AMBy saying "the low resistance test" are you referring to the Shorts Check that is run before a normal scan? When the Shorts Check is run is the 47Kohms fixture attached? If so then an open would not really be an open (horizontal signature). It seems like your high resistance test would detect opens as well.

Yes it does show on the high resistance test.
If the trace is south of the stored trace its open circuit, and if its north of the stored trace there is a short circuit.
This all refers to the test using a bank of sixty four 47 K Ohm resistors.
One end to COM and the other end to each channel.
I run the shorts test first that shows all links that should be there on a 64-way IDC connector.
Plus any that shouldn't be there.
Then run the high resistance test at settings of 1 KHz, 100 K Ohm, 20 V.
The high resistance test shows all sorts of nasty goings on under plug / socket housing as discussed on this Forum.
But as the low resistance test comes first it would be useful to see any open circuits that shouldn't be there.

Last post by admin - February 09, 2023, 06:17:00 AMWouldn't a regular scan find an open circuit?

As you may be aware from previous communications on this Forum & emails I frequently run the Shorts test using Workstation 4.3 on my ProTrack & Scanner setup.
The program readily shows when there is a short under whatever value it is set at.
But doesn't tell you if you have an open circuit.
Is this something you might include in a future update?
Would the same problem occur with the 3200S?

Last post by admin - February 06, 2023, 07:49:09 AMThe CD manual will not have any information on the HS20USB.
The J402 serial connector on the HS20USB was intended to be used to daisy chain additional controller cards. I still think it is pointless to try and connect to the Prober this way.
