Desktop computer is windows 7, so that might have a lot to do with it...

Maybe I'll just stick with the windows XP laptop, as that at least works sometimes...

Hi ThyDntWntMusic,

As others have said in this thread, problems with the WT3 are 99% of the time a PC/OS issue, not a faulty WT3 tester.

The WT3 tester is a great tool when its working properly and here’s my findings to have it working without issues:

1. First of all, always plug in your WT3 tester in the USB port before starting the WT3 software. Give the PC a couple of seconds to recognize the device before starting the software.
2. In the Control Panel\Hardware and Sound settings (win7) check the following settings for your WT3 device (USB Audio Codec):

a. Playback\Properties\Level. Set the volume to 100
b. Playback\Properties\Enhancements. The Enhancements properties should read “Status: Disabled”.
c. Playback\Properties\Advanced. Default Format: 16 bit, 44100Hz (CD Quality). Exclusive Mode: Both check boxes marked.
d. Recording\Properties\Level. Set the volume to 1
e. Recording \Properties\Advanced. Default Format: 2-channel 16 bit, 44100Hz (CD Quality). Exclusive Mode: Both check boxes marked.
f. Sounds. Sound Scheme: No Sounds.

3. Give the WT3 tester a 2min warm-up before doing any measurements or calibration.
4. Connect the calibration resistor and do an “Impedance Calibration” (It’s not needed to do this every time you start the WT3 tester, but if you think your calibration is corrupt or if you have “Restored the Default Calibration” it’s necessary to redo it.
5. Do a “Test Leads Calibration”. It should be in the range of 0.26-0.30 Ohm. The “Test Leads Calibration” can be done every time you use the WT3 tester.
6. Make a test “Impedance Sweep” with the calibration resistor connected. You should now get a smooth measurement.

My general recommendations are:
1. Buy a better precision “calibration resistor”. Mine is in the range of +/- 0.1%
2. If having strange readings, try to “Restore the Default Calibration” and then redo the calibration.
3. Always use the same USB port every time you use the WT3 tester. Use a USB port that’s not shared with anything else. If you have problems, try switching USB port until you find a stable one and redo the above calibration.
4. Try the WT3 tester in a different PC/LapTop

I’m sure you have done most of the things above and you might actually have a faulty unit, but perhaps there are other readers of this thread that found it useful in their problem solving.

Personally I’ve had very little issues with my WT3 tester, but it can occasionally occur. Then I follow the above instructions.

Regards

/Göran

I have followed all the steps that Goran outlined and have had no problems at all. It is a great little piece of gear.

Update your software if available. My DATS didn't work with windows 7 until I was running the latest Dayton software.

That pretty much was the answer, it was set to 1 channel... I assume the channel it was set to wasn't the channel that WT3 was measuring from

Thanks!
