1.0 INTRODUCTION
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 filament 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 measure 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.”

13.0 REMOVING PROTEC TIVE RUBBER SHELL
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.

2.0 SAFETY PRECAUTIONS
All operators should wear safety goggles when using this or any other
tachometer. Failure to do so could result in serious injury!
1. Check condition of housing, slide-on Contact Adapter and
split mounting hubs of push-in Contact Cone, Surface Speed
Wheel and any other accessories. Replace those that are worn,
loose-fitting or cracked. The Contact Adapter shaft should
rotate freely.
2. When operating in the contact mode, be sure Contact Adapter
fits snugly into the housing grooves.
3. When using the Surface Speed Wheel accessory, make sure it
its the tachometer shaft snugly. In operation, keep the wheel
perpendicular and parallel to the moving surface to prevent it
from running off the tachometer shaft.
4. Do not use the standard surface speed wheel for speeds in
excess of 1000 feet per minute. For higher speeds, specify the
optional Heavy-Duty Surface Speed Wheel (DT12) with
set-screw mounting.
5. Store the instrument in its carrying case when it is not in use

10.0 MEMORY SYSTEM
The YSL-2000HD is supplied with
a built-in memory system which
stores the last measurement, maximum
measurement, minimum measurement,
and the average measurement which
occurred during a measuring period.
A measuring period is the interval of time while the Measure key is
depressed. The stored values are retained in memory even when the power
turns off (auto power off). To recall the stored values after auto power off:
1. Press the Measure key to turn the power on
2. Press the MEM key to recall the desired value
The Memory key accesses the YSL-2000HD’s built-in
memory. Each time the MEM key is pressed the values
stored in memory will be recalled to the display in the sequence listed
below. The appropriate memory indicator will be shown together with
the recalled value on the display.
Note: When the batteries are removed, the values stored in memory
will be lost.
