Hi, this is Steve from Drumdial Incorporated. This is the official Drumdial service and calibration video.
This video will show you the proper way to calibrate your Drumdial.
Some parts of the Drumdial are used for calibration
and others are not. For example this is the top cap screw assembly. No matter what
you may have seen or heard, it should never be loosened or removed.
it is not used for calibration.
It simply works as a bumper that keeps this shaft from going to far down and
getting stuck inside the tuner.
I have seen a few of these and hopefully this video will save you from having to send your Drumdial in for repair.
The O-ring bumper under the cap screw is supposed to expand and contract a little bit.
If the top cap screw is loose the O-ring just doesn't work very well as a bumper.
When you're holding your tuner and there's no tension on the Drumdial. It does not need to be at zero.
This does not mean that your Drumdial is out of calibration. This is normal. Remember,
the top cap screw has nothing to do with calibration.
This is the tuning tip.
When you're ready to calibrate check to make sure that the tip is finger tight. Don't use pliers (or tools)
to tighten.
This is the bezel. The black ring around the Drumdial face.
The bezel lock is the locking screw, at about the 1 O'clock position.
The large needle in the middle is used for calibration and for tuning your drums.
The small needle is not used for calibration or for tuning.
As a matter of fact the small needle is part of our logo and the small red numbers are used
for quality testing here at the shop.
To check calibration of your Drumdial, Set your tuner on a clean, lint free piece
of glass. The large needle will rotate a few times.
This is normal operation and pre-loads the internal spring. This one looks good.
Don't set the Drumdial on a plastic counter
or wood to check for calibration. Like I have done here.
Let's compare the readings from this piece of hard wood and the glass.
As you'll notice, this isn't quite calibrated. It is actually
measuring the fiber tension of the wood.
Here on the glass it is in perfect calibration.
This Drumdial is out of calibration. So let's check the tuning tip.
It's snug, so let's go ahead and calibrate this Drumdial.
The first thing we do is loosen the bezel lock. Then rotate the bezel to align the large needle
with zero; and then
relock the bezel.
That's the complete calibration process. It's as simple as that. Your Drumdial is now calibrated and ready
to go tune some drums.
As always here at Drumdial we appreciate your questions and helpful comments. May your drums stay in tune
and always sound great!
