We
have had several customers ask how they can test their 507C
Sonic Tension Meters in house? And, What kind of testing device are
we using - which is shown on our website? You can easily check the Calibration
yourself, in house, as we do on all 507C Sonic Tension Meters that we sell!
We
check the Calibration using downloadable "Guitar Tuner" software
on an iPhone! If you have access to an iPhone,
iPad or, a 2nd or 3rd generation iPod
Touch with an external mic connected to the iPod
Touch - just download the Cleartune - Chromatic
Tuner application for $3.99 US from the App Store on the iPhone.
We set the Cleartune software at 440.0
Hz when we test the Sonic Meters, or any optional sensors and we
have never found any out of calibration.
You
can use any frequency you want (and we have) as the Sonic Meter shows how
accurate it is at all the frequencies but, we settled on 440.0
Hz for all units being shipped. Note:
you can use any tuner that displays the frequency it is generating!
Please
see the complete technical explanation of the Sonic Tension Meter Accuracy
below and thanks for using the Gates
507C Sonic Tension Meters.
