All user reviews for the Meisel COM-90

I've had my Meisel COM-90 for perhaps 12 years (?). It has, and continues to serve me well for tuning my guitars all that time. I recently bought an autoharp and as far as I can tell it won't work for the purpose. It simply won't give me any notes but the normals (term?), i.e. no flats or sharps. It indicates below or above the notes for a guitar but no accuracy for flats or sharps. I don't know if the newer models are different in this regard but it seems I need to buy a new, or different, tuner for my autoharp.
