Out of Production Hardware / Re: Other uses for a ProTrack Scanner
« Last post by admin on January 26, 2022, 09:10:11 AM »
Update to this test method developed by James--

It is possible to use Huntron Workstation to control the scanning with this setup.

The ProTrack is connected to the Scanner by the interface cable only and a Workstation supported DMM test line can be connected to the Scanner Channel A BNC connector. The COM connection on the DMM is connected directly to a common line that goes one side of all resistors on the fixture. The Channel A Scanner interface is connected to the fixture through a ribbon cable.
The test in Workstation is setup to use the Scanner as the Connection Type (set at the Component level).

The advantage here is that Workstation can be used to store and compare the measured DMM values captured through the ProTrack Scanner essentially using it as a switch matrix.

There is a tutorial on the Huntron website that discusses using a DMM with Huntron Workstation:

Check the range resistors on the ProTrack input circuitry. Damage to these is the common problem we see.
Thanks.

Try reprogramming the Flash Prom on the ProTrack.

Does it work well when used in desktop mode (without a workstation)?

I have replaced all of the relays , listed in the report and still getting the same error.
Any thoughts ?

Have enclosed the complete report file.

serial number KJ3 version: Starting around the front "A" channel corner: 
K33 relay (channel A is short to channel B),
K34 relay (channel A is short to GND),
K35 relay (channel A input relay - front banana socket),
K45 relay (channel B input relay - front banana socket),
K36 relay (channel B is short to GND).

They are located under the CRT.


serial number KJ2 version: Starting around the front "A" channel corner: 
K33 relay
K34 relay (channel A is short to GND)
K35 relay (channel A input relay - front banana socket) (double pole single throw contact)
K36 relay (channel B is short to GND)

K45 relay (channel B input relay - front banana socket) maybe soldering side?)

They are located under the CRT.

Hello

Can anyone tell me where the K45 relay is located on the main Board , I have located the other three any help would be great.

Thanks

Perhaps if someone else has one of these old Trackers they could use this inexpensive Universal Programmers to copy the program if that is possible?
