22、Generator Unit Figure 18 Distortion Meter -11 - AL-61 Note II Initial Setup 1. Place the gauge plate in a tape transport just as a cassette tape is normally inserted. (Some transports may require cover removal to make easy access to the head and guide area.) 2. Firmly seat the gauge plate on the hor

23、izontal locating-surface. The gauge plate has been machined flat to within 0.051 millimeters; therefore, it will indicate any height errors to the locating surfaces. The gauge plate should not rock if the transports cassette locating surfaces are properly adjusted. 3. Bring the heads into the normal

24、 play/record position before taking any measurements as detailed in the procedures to follow. Tape Guide Measurement (Figure 19 Place the guide-check bar on its side on the top surface to the gauge plate and slide the bar up to the record heads tape guide fingers. The bar will exactly slide into the

25、se fingers if they arP. at the proper height. This will indicate the guide height with respect to the top gauge plate surface. This height is chosen as the nominal lower tape edge position with respect to the Phillips standards. If the guides are high or low, adjust the head and/or adjust the tape g

26、uide to the indi- cated height. Figure 19 Head Perpendicularity Measurement I Figure 20 and 21) 1. Position the square end of the guide-check bar against the head surface at its apex. 2. Observe the tilt of the head by using a flashlight to back-illuminate the head-to-bar interface. When the head is

27、 prop- erly adjusted, no light will show. 3. If required, place shims under the head fixture on the transport to eliminate tilt. An offset dental mirror is useful for checking head tilt.
