Rocktuner CT2 problem

Question

I have a problem with a piece of equipment I have. I've found in the old locker this tuner, and wanted to tune my guitar with it. But after I do that, I find that my guitar is 2-3 pitches higher than it should be (I used standard EADGBE). This tuner has three modes: bass, guitar and wind instruments, and I assume that my problem is because the different mode is turned on. Maybe if anybody used or use this tuner, he could give a tip, how should I use it. I tried all buttons, but the mode is unchanged.

I also cannot get, how clefs (keys) are working and why they are needed, and should I set my pitch to 440?

My default screen looks exactly like on the screenshot under the link, with a letter C in the lower right.

Answer 1

Remove the battery.

I think it is set to some other base pitch for a transposing instrument, like an E-flat clarinet, so while it is probably calibrated correctly, it is not displaying the same note names as on the piano. I don't think A=440 or A=450 or some other tuning is the issue. You want to get it back into "guitar" mode.

Usually the easiest way to re-initialize this kind of electronic device to its default mode is to remove the battery, wait a few minutes, and put the battery back in. Try this and see if it solves the problem.

Update:

I found a list of the features of this particular model of tuner. To wit:

http://www.amazon.com/Rocktuner-Auto-Chromatic-Clip-On-Guitar-instr/dp/B003VKB74E

• 3 Modes: Guitar, Bass, Wind instruments
• 4 selectable keys: C, F, Bb, Eb
• A4 calibration: from 430 to 450 Hz

The person asking the question said that the tuner is displaying 3 half-steps away from where it should be.

But A=415 is one half-step lower than A=440, and A=466 is one half-step higher than A=440. Note that this tuner can only accommodate from A=430 to A=450, which is less than a half-step in either direction. So this is clearly not what the person asking the question is experiencing.

Therefore, the problem is that the tuner is set to accommodate a transposing instrument in F, B-flat, or E-flat, like the list of features says. E-flat tuning is three half-steps transposed from C tuning.

The person asking the question needs to get his unit back to C and out of the Eb key transposition mode.

Here is how to do this:

• Hold down the button labeled "Key".

• Use the up and down arrow keys until the "Key" transposition indicator on the unit’s display, in the lower-right corner, says "C" and not "Eb" or something else.
