Checkline MLT Portable Yarn Tension And Rate Meter, Tension 0 - 50 cN, Yarn Speed 1,000 m/min or 1100 yd/min. The Checkline MLT Portable Yarn Tension and Rate Meter is a stand-alone electronic apparatus for accurately measuring and displaying three (3) quality-critical parameters involved in knitting, namely, yarn consumption, yarn tension and yarn speed. All contribute to producing repeatable, uniform quality fabric and products from circular knitting machines with rotating needle cylinders and flat knitting machines, including all body, hosiery and sock machines. The Checkline MLT Portable Yarn Tension and Rate Meter displays the Normal, Average and Peak values for yarn tension. All values are shown on an easy to read back-lit LCD display. A unique, trigger-operated, yarn access system provides easy and sure yarn access and contact with a yarn tension-sensing pin and a yarn speed wheel, while a machine frame-mounted sensor counts revolutions every time a specific, rotating or moving magnetic part passes it, to provide machine RPM and yarn consumption information. This easy-to-use instrument accumulates the data required to produce repeatable, uniform material and products from one machine to the next, even when using different cylinder diameters.
