<p>PURPOSE:To speedily and easily attain highly precise adjustment by quantizing the reproduction output signal of a standard tape, obtaining and displaying an allowable range and adjustment completion both of which correspond to an adjustment state quantity, an adjustment direction and adjustment completion from an output level. CONSTITUTION:When the reproduction output signal of the standard tape is inputted to an output signal measurement part 10, an amplifier circuit 13 amplifies it to a measurement level, and a peak detection circuit 14 detects a peak value and holds it. The signal is digitalized in an A/D conversion circuit 15 and is stored in a storage circuit 16. Then, a data processing part 11 reads data of the circuit 16, obtains the allowable range corresponding to the adjustment state quantity, the adjustment direction and adjustment completion by an operation expression calculating information required for adjustment and judges the completion of adjustment. Then, information and a scale showing the adjustment state are displayed in a display part 12. Thus, an adjuster can speedily and easily attain highly precise adjustment without the necessity of special skill.</p> |
