Electronic tuner not working correctly (?)

I tuned my bass this AM using my Korg CA-30 tuner. It's been accurate up to now.

When I then started playing, I noticed that my E string seemed to be almost 1/2 step flat. All other strings sounded fine. I checked and re-checked the E string and the tuner said it was fine, but my ears did not. I raised the E string one-half step and it now sounds in tune. But the tumer says that the E string is way too sharp.

Is it possible for the tuner (which was not expensive - maybe $25) to just go out of tune (on one string) ?

It might be, or you accidentally recalibrated it. Did you try turning the tuner off and then using it again? If so, did that change anything?

Is the tuner set to 440hZ?

We use CA-30s at our school. In the top left corner of the display you'll see the pitch it's set for - it should say "440HZ". If it doesn't, use the up/down buttons next to "CALIB" until it does, then give it a try.

I've had trouble with the E-string on some tuners. Try checking it with the octave harmonic. Also, try using just your neck pick-up (assuming you have two), and/or turn down the tone to reduce the high-end.

Ive gone strictly to strobe tuning, but I seem to recall that the Korg I have laying around here somewhere always seemed to give erronius readings as the batteries were starting to get weak..
