Hi every one, Was wondering if someone has info on the failed item I got on the scanner while performing loop calc.
V=5 R=0 F=18 Pin 51 (K51 and K115) Ch. A MaxDif=90 Tol=6
Failed ***
I purchased the CD manual, don't know if the info is there or not. but the CD been misplaced and cannot find it.

Hi
What results do you get on the other Diagnostics tests?
Have you checked the various supplies on your ProTrack?
There are some isolated supplies for the Scanner.
I found out about these when I accidently connected a 12 V.D.C. PSU to my Scanner.
It blew up a few components as described on this Forum.
The Scanner prefers a 5 V.D.C. PSU.
I read your post about the scanner and 12 volt power supply. That's one of the reasons I'm careful now, thank you.
The protrack by itself passed the loop Calc. The power supply for scanner is 5 V 4 amp.
Hi there, ProTrack is failing in the Loop Calc Phase check and Volt check. I was wondering if someone could help figure this out, Please. I think all the fails are related to 1 or 2 component!

I may have figured it out the Scanner fault. but not sure until I replace the relay 51 and 115.
both relay 51 and 115 are connected to Pin 51. When energized measured resistance between their contact is higher than the rest of the relays. Measured at around 280 to 290 mohms.
the rest of the relays measured around 120 to 180 mhoms. datasheet says 150.
relays are obsolete but thanks to jvthorsley, he posted the equivalent relay part #. I think I managed to burn a couple of relays while testing too. Kept forgetting to turn off the supply to the relay coil when solder / de-soldering line. I will be replacing 4 of them.
The failed voltages are reading slightly high. Have you tried running the Auto calc in the ProTrack (KJ3 and KJ4 ProTracks only).?
No I have not tried running the Auto Calc on the unit itself I will try doing that a little bit later. I tore everything apart in the lab to rearrange and make some room.
What are the voltages that need to be checked on The ProTrack?
1. Warm up the Protrack for 30 minutes.
2. Enter the Calibration menu.
Press Help button. Do not release it yet.
Press Menu button. Do not release it yet.
Press right side 4. button and release all three buttons.
Here, press the Auto on the right side to start the calibration.
The procedure runs for 20 minutes.
Run Workstation 3.5.4 with Win XP only.
Run the meter check in a Workstation (for this you need a 6.5-digit dmm, e.g. Agilent 34401)
Then try loop calc.
Maybe all values will be good.
Thank you fetron. I am going to try this very soon.
What is the right side 4 button?
I have an Agilent 34410.
Fourth button down on the right. Here is a graphic that anyone with KJ3 and KJ4 models may find useful.

Perfect thank you
performed the Auto Calc. it passed the Loop Calc. I humbly Thank you guys, I appreciate you very much.
All that is left is repair the scanner test in WS.
waiting for relays to arrive.
I will update
hi everyone, I replaced the relays. but it got worse. now scanner fails in loop Calc almost on every relay I think.
it does not scan in the manual mode either, what I mean is with out the computer. channels don't read the same.
I replaced 4 relays, replacement part #HE722A0510.
It's highly unlikely but , I thought i plugged in the 2 prong incoming 5V plug in the wrong jack on the board.
I make a point of taking pictures of work before disconnecting, but it looks like i don't have any picture...
there is J3, J4 and J5 Jack's on the board.
J4 is obvious but I thought maybe I swapped the J3 and J5 by mistake. can someone tell me which one the incoming 5v power connects to. ,
Also can I get schematics on the ProTrack Scanner please.
Hello!
Scanner schema on the forum page.
https://huntron.com/forum/index.php?topic=307.msg1223#msg1223
Open the all-protrack-schematics.pdf
Power for the Scanner splits off into two plugs. J3 is the power for the Scanner. J5 only supplies power to the front panel LED. Pin 1 on J3 is power, pin 2 is GND.
The LED supply J5 has them reversed. Not sure who at Huntron thought of that one! Check the internal fuses.
Hi A11234
J5 goes to the power on indicator LED.
J3 5 V.D.C. in. Note polarity of Tantalum capacitor for polarity.
J4 Three BNC connectors.
See my attached photo.
Thank you for the information.
It looks like I had the plugs in the correct order after all.
Internal Fuses! Must be the pico fuses. I will look for them as soon as I get back to the workshop tonight.
Voltages on the ProTrack! still not clear about them. A little bit more information about the voltages if possible please.
ProTrack passes all other tests with flying colors.
What voltages are you referring to? Does the ProTrack fail the Voltage test?
ProTrack is not failing voltages. Jvthorsley was suggesting I should check some voltages on the ProTrack a couple of massages ago.
He wrote "What results do you get on the other Diagnostics tests?
Have you checked the various supplies on your ProTrack?
There are some isolated supplies for the Scanner.
I found out about these when I accidently connected a 12 V.D.C. PSU to my Scanner.

Just to add more info when I do the manual test with the scanner it seems one of the channels several relays on the scanner does.not even close. the signature stays flat and open.
The power circuit in the Scanner does have DC converter. Check the output for 5Vdc. The relays are all triggered by a 5V signal. You have the correct RJ45 cable from the ProTrack to the Scanner, correct?
Yes I do have the correct RJ45 1-1 through 8-8.
I tested the RJ45 cable with a network mapper/cable tester. My mistake, cable I was using was a crossover. I have a tested and verified good rJ45 between ProTrack & Scanner now.
I can test up to 40 pins with the leads I own at this time. using the scanner in manual mode without the computer, It seems to be OK. Used it without the computer, in Compare mode, tested over identical ICs, it passed with tolerance set at 8. But, had a few failed pins with tolerance set at 5, even though the signatures looked identical. that is why I figured I got to raise the tolerance. I am not sure if its the right way of doing this either. please correct me if I am wrong.
ProTrack by itself connects to WS no problem.
but still unable to connect both ProTrack and Scanner to WS. Scanner fails the Loop Calc test. everything passes perfect on ProTrack, but the scanner.
On the Scanner board measured all relay coils, all except 1 are between 190K, 200K Ohms. the one that is different coil reads 130-140K ohms. it is a different manufacturer's. board's been worked on before.
both F1 and F2 are good.
should I assume the DC to DC converter is OK since it works in manual mode as I explained above?
Should I do a calibration on ProTrack with the Scanner connected? I remember clients that had to calibrate the torque on thier hanpiece motors before use. The mistake they were making was calibrating the torque without any attachment connected to the motor. motors were weak during use!...
little History on this scanner : could it be possible that I damaged a trace or one of those ICs while testing relay coils.
before replacing the relays, while soldering leads to relays to test the contact resistance on suspect relays and a few to compare...I forgot to turn off the 5V power supply and used the soldering gun on the relays. this seemed to burn out the coils on the relays, they did not respond after that. that's why I had to replace 4 instead of 2.
below is the loop Calc result.

Scanner Test FAILED ***
Calibrating ProTrack while scanner is connected did not help scanner pass the Loop Calc. :'(
During the Loop Calc I unchecked the Resistance Verify in the scanner test window. the Loop Calc went through. I had to do this a couple of times. now the ProTrack and Scanner are connected to WS. but I wonder what affect does the unchecking of the resistance verify would have on the accuracy of the scans? is this OK?
It appears there is some low level resistance that is causing the failures. Channel B is worse than A. Maybe try a different set of BNC cables between the ProTrack and the Scanner. Use cables that are as short as possible. Also clean the the BNC connectors with some alcohol.
Got it. Thank you. I will do. They are cheap BNC cables from eBay. also looking at the bottom mounting screws on the scanner it looks like scanner been sitting somewhere moist at one point before I got a hold of it
For everyones benefit, some additional information about Loop Calc.
The Loop Calc is a function that will compensate for the capacitance of cables attached to the ProTrack. These "cables" can be test leads, the Scanner (and connected cables) or a Huntron Prober.
The Loop Calc is a separate function from the other Diagnostics and can be executed without having to run the other tests. Right-click the Loop Calc button then left-click the Loop Calc button and the software will run Loop Calc only. Loop Calc will only fail if it cannot compensate for the capacitance at any particular range. The high resistance, high frequency ranges are particularly susceptible to failing if cabling attached to the Tracker is too long.
With a ProTrack and Scanner connected through Workstation, when the Loop Calc is run you should also have your test cables connected but not attached to a PCB or component. Pin 1 is automatically enabled during Loop Calc to ensure that the added capacitance of the cable is correctly compensated. Loop Calc will save a file based on the hardware configuration so you can have several loop compensation files if you have a ProTrack, ProTrack and Scanner, or ProTrack and Huntron Prober.
Wow nice thank you so much. good to know
I have a question, in the failed scanner loop Calc above, what is the MaxDif= what are the units of these numbers? Milliohms?
I have a question, in the failed scanner loop Calc above, what is the MaxDif= ? what are the units of these numbers? Milliohms?
MaxDiff is the difference in signature data that is above 0 when compared to our reference values. If MaxDiff excedes the Tolerance (TOL) then it will fail that step. The units are the data points derived from the signature waveforms. Here is a more in depth explanation about Tolerance that I wrote for the old FAQs on the website:
What is Tolerance and how is it calculated? (https://huntron.com/sales-support/faqs.htm#2Q1)
Perfect thank you I'm going to read that as soon as I get out of the car:-)
I got much better and shorter about 16" coax cable by Pomona and shorter good quality network cable. Scanner still not passing the loop test lots of fails
We 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.
Thank you. I will go through the unit this weekend.
Let me see if I can change the title on my side to what's recommended.
I don't seem to know how to change the title but please feel free to change it to what you think is appropriate for the Forum.
