Shorts in the M Ohms range show breakdown of insulation between connector pins under the connector housing.
I have attached a few examples of problems found under connector housings.

not for workstation but for the trackers: How about a function that allows to hold the signature in Tracker's screen while measuring the reference or dut to compare. sometimes computer is not available and when dealing with very small contacts, hard to reach areas.....

Hi everyone, I have a question. I want to reduce the current a bit at the low setting (10V), but I can't figure out which gain resistor I need to change: R173 or R155? I'm talking about the resistors at the input of the 74HC4052 integrated circuits.

Nice, congrats on you new toy.
when you say hi resistance short. what is the resistance you get on that short. I think, I am dealing with a hi resistance short that is why I am asking. but the short I am working on seems to be between the layers, I think, but yet to be confirmed.

After some years of fixing various problems on my ProTrack + Scanner but still giving intermittent  inconsistent results usually with urgent jobs decided it was time to upgrade.
I was lucky to find the the U.K. distributor over here, CTS Combined Test Solutions had a demo 3200S available for sale. And at an affordable price.
But still needed to connect the Tracker to my DMM (Agilent 34410A)  using Workstation 4.3.
The photo below shows an example of high resistance shorts developing between pins under the connector housing.
This particular PCB is used on a Combine Harvester. 12 V.D.C. system with lots of available current that can cause a major burn-up when shorts as shown develop. Caused by a mixture of humidity & dust.
These shorts don't always show up when just relying on the 100 K Ohm range on the Tracker.
The 3200S has all the usual stuff as a ProTrack + Scanner but no output from the Scanner to connect to my DMM.
The connections on the back of the 3200S are designed for Huntron Probers.
I removed the top off the 3200S and worked out the necessary mods to achieve what I needed.
First cut the two outer wires going to Ch. A & B BNC connections on the rear panel from on Plug J4 on the logic PCB behind front panel V & A switches. But kept the centre lead on J4 going to COM BNC plug on the rear.
Then took a lead from the red wire on J7 (near to PSU) to BNC plug formally Ch. A connection and now labelled "Output to Tracker / DMM".
Next took lead from red wire on J6 (Behind ESC, up & down switches). This red wire goes through a transient suppressor choke mounted above J6. Then took the red wire to BNC plug formally Ch. B connection and labelled this "Input to Tracker".
And when using the 3200S in "normal" mode linked the two former A & B BNC connections with a short BNC lead as shown on photos here.
For measurements with my DMM removed BNC linking cable on rear and took one lead from DMM to "Output to Tracker / DMM. and other lead to an adaptor board using IDC ribbon cable from front panel IDC plug on the 3200S. Whichever pin is used on the adaptor board determines the connection to reference to for resistance measurements.
This mod enables me to make measurements to the first 64 pins on the front panel IDC connector.
I have mentioned previously on this Forum details of the adaptor to make measurements on my ProTrack +Scanner. The same method applies here.
And after doing this run the Alignment tests with the top back on the 3200S & BNC cable linking the two connections on the rear side.

Hi Refam and welcome to the forum.

Here is a link to the technical reference manual for the 5100DS. It should be a good starting point.

Out of Production Hardware / 5100DS testing

Last post by refam - December 16, 2025, 06:36:44 PM

Greetings all. I purchased a 5100DS. It appears to have all the cards (slots are all filled) and it responds to shorting out the probe connections breifly.
So, is there a routine or list of tests I can perform to check for faults or calibration errors?

yes, the bottom bootter chip is the one needed. bottom bootter, bottom booting all the same, tomato/tomahto
