Good to hear you are putting the tester to good use. 50--Wow. You purchased the tester in June 2009, BTW.
"BTW is there an easier way to send the chart to my customers than "print screen & ms-paint"
Yes, you can email them the ".WDQ" file and have them download and install the WinDaq Waveform Browser software. No charge for that. (

Keep in mind, however, they can modify the display settings in the browser so you may get calls asking about some weird display they have configured, accidently or otherwise.

PS: Would you email me the 3 images you posted? They may help me diagnose a customers problem in the future. Thanks!
