The CHECK•LINE® YSL-2000HD is supplied with two (2) special -purpose
measuring heads which converts it tinto any of three separate instruments
detailed below. the units of measure are user-selected and shown on the
LCD Display along with the measured value.
Yarn/Wire Speed & Length Meter
With the Yarn/Wire Speed & Length Meter Measuring Head installed, the
YSL-2000HD accurately measures the speed and lengths of yarns, wires and
similar filaments., The measure head is comprosed of a precision , low-inertial
measuring wheel and a “wrapper” roller. The “wrapper” roller directs the fila-
ment over the measuring sheel to maximize surface contact. Thishelps to
eliminate filament slop and breakage, especially when measuring fragile
yarns, fibers and fine wires.
Contact Tachometer
With the Contact Tachometer Measuring Head installed, the YSL-2000HD
can be used to measure the rotational speed of rotating motors, shafts, pyulley,
gear, etc., using the conte or funnel tip adaapter. In applications where surface
speeds (conveyor belts, printed materials, webs of paper or fabric, etc.)
are to be measured, the universal wheel is used for direct readout in feet/min,
meters/min or inches/min, as selected by the user. It can also be used to meas-
ure the accumulated total of continuously running material, such as paper,
wire/yarn beng wound on a spool or for checking the calibration of
on-line counters and totalizer devices.
Non-Contact Tachometer
Without either Measuring Head installed, the YSL-2000HD can be used as a
Non-Contact Tachometer. In this operating mode, a small piece of reflective
tape is applied to the rotating element (wheel, shaft, etc.). it uses a visible
LED light source to accurately measure the RMP for up to 14" (350 mm)
away from the “target.”

The gauge is supplied with a durable rubber shell that provides an added
measure of physical and environmental protection in harsh applications.
To remove the shell, follow the procedure outlined below:
1. Using your thumbs, slide the rubber shell
up and off of one corner of the gauge.
Repeat for the other corner
2. Pull the shell down until it is completely
off the corners of the gauge, the pull the
gauge forward and out of the shell.
3. Replace the shell by sliding the gauge
bottom first into the large center opening,
then, one at a time, slip the corners of the
shell back over the gauge.
