The Replacement Contact Tip Pack includes rubber concave and convex tips (1 each) that are part of the Remote Contact Assembly (RCA) used with the PLT200 Tachometer. (Remote Contact Assembly and replacement 10 cm Linear Wheel sold separately.) Connecting the RCA to the PLT200 Tachometer makes it possible for contact measurement.

Measurement of units in addition to revs requires the attachment of the assembly and tips or wheels (10 cm and 12 in. options). With this attachment, the unit can measure RATE inputs-revs, inches, feet, yards, centimeters, and meters either per second, per minute, or per hour, as well as miles per hour.
