    Brainer,
    Did you ever try changing the hardware setting to WT3? Based on the original screen shot you posted I'm pretty sure that's all that was wrong.
    This was likely a complication that resulted from using DATS V2 software with WT3 hardware. That combination requires a change at the Preferences dialog to let the DATS V2 hardware know it is being used with WT3 hardware. But perhaps the WT3 hardware unit was dying. In the later hardware I added diode protection to prevent the units from being damaged by voltage spikes returning from the driver when the cone is displaced.
    I have the DATS 1 hardware and previously was unable to get it to work with the V2 software. It worked okay with the V1 software. Then i saw your post 23 and tried out the option specified there for using the older hardware with the V2 software. It worked like a champ and I've been using the V2 software ever since.

    And, as for whatever version of DATS software I should use, that didn't make any difference either. I tried the original version that came with the WT3, ver. 2.x and V3. No difference.
    So today, the thing went into the garbage.

    Thanks anyways.

    Just to follow up somewhat... my WT3 seems to be pretty finicky but, luckily, I can get it to do what I need running Windows 10 and the DATS software. My latest frustration seems to be that it doesn't like to sit long before providing reuslts that look like a bunch of uncalibrated noise. Fortunately the diffence between a valid plot and a garbage one is obvious so I'm not worried about mistaking bad data for good.

    The solution is to disconnect the USB and close the DATS then restart DATS. For extra measure I make sure the leads are open when connecting and then let it sit for a minute or two after starting everything. A quick calibration will show if it's working properly.
    Part of my journey to getting this far was that I didn't know what the calibration curves are supposed to look like in order to verify correct operation.

    My leads calibration does show some odd noise starting at 8k. I'm not sure if this is normal but that is well outside of the range I need to gather specs in so I fine with it.

    My results so far have been repeatable to well within reasonable tolerances.

    I dunno. It worked for me. I get completely straight lines. And it looks like it worked for this other fellow too:

    The only other thing I can think of is changing the record volume to 54 (weird number)

    Great tech support John and PE.

    That should resolve all your issues Brainer.

    The WT3, DATS, and DATS V2 are not compatible with the DATS V3 software.
    The newest version of the DATS V2 software, version 2.1.2, is available for download on the product page: DATS V2 product page
    You can find the download in the "Manuals & Resources" section.

    I hope this helps.

    Can you use DATS software ver. 2.x with an original WT3?

    Thanks
    Hi Brainer,

    Yes, you can use DATS V2 software with WT3. You just need to make sure the switch at Preferences is set correctly.

    The rolled off high frequency shown in your screen shot is typical of the mismatched setting. The is a 1 sample offset difference in the TI PCM2900 processor versions used in WT3 versus DATS. That is what the preference setting adjusts.

    I think my solder joints on the PCB are at least slightly cold. However, when I measure resistance from each alligator clip to its corresponding PCB solder joint, I get a resistance of only 0.1 ohm. Again, I wouldn't think twice if it weren't such a small joint and I didn't have neurological tremors in my hands. I may try it, as I don't have much to lose, I guess.

    Would one of you be willing to take a clear closeup of the PCB on the side with the crystal (marked G12.000 on it). I think there may be some issues with some of the other solder joints as well, but again, I'd like to be sure before I take more risk.

    My WT3 had a cold solder joint where the red test lead landed on the pcb. I reflowed that one and another questionable looking solder joint and it's worked perfectly ever since. I later upgraded the s/w to DATs so that I could measure inductors and caps. It works on both my laptops, one with Win 7 and the other with Win 10.

    Yes, I thought of that. I'm trying that now. I'm also going to do one better and check resistance between each alligator clip, and the solder joint inside the plastic case of the WT3 (not the end of the clip).

    Can you hold the leads of a DVM and place them upon the ends of the cables/clips and have someone jiggle the wires to see if your resistance readings vary with the movement of the lead wires?

    Try something, anything to eliminate possibilities/issues so you you can track down the problem.

    What new skills am I going to learn? I'm already quite good at soldering. Part fo the problem is I have a chronic illness that makes my arms tremor. Doesn't make for goos solder joints. But yeah, maybe I'll try it. How would one buy and use similar insulative jackets to replace the ones that are on those clips?

    It can't hurt to try and make all wire connections solid at this point and you can learn/practice some new skills in the process, young man.
    The alternative is to wonder and chase your tail and spend more money on a new unit . . . Give it a go, Sir.
