Thread revival.

Thanks Lance, I bought your basic tester back in 08 or somewhere around there. Lots of bleedy knuckles later I just performed the 50th compression test for yet another happy customer.

Over the years ive sampled quite a lot of charts, heres a select few for your promotional viewing pleasure.

First one is a 20B front chamber releasing its carbon grip on an Apex seal.

Second is a 12A race engine coming out of a one year hibernation (slow starter)

Third is a well build one rotor NSU Spider

Nextmonth im off to the Danish RX club track meeting, where your brilliant tester once again will be on duty.
BTW is there an easier way to send the chart to my customers than "print screen & ms-paint" :-)

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. (http://www.dataq.com/support/upgrades/playback/). Click on the download for the basic version 2.91 at the far left of the page.

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!
