Pressure on the spring-loaded outer ring which exceeds the
range of the instrument by more than 100% may cause permanent
damage to the measuring spring and must be avoided under any
circumstances.

This device must not be operated in explosion hazard areas and
must not come into contact with aggressive substances.

1.0 INTRODUCTION

This manual covers the operation of both the Checkline TEXTILE and
SHORE Durometers. Textile Durometers are typically used to check the
relative "firmness" or "hardness" of textile yarn packages, bobbins, beams,
spools, cones, etc.They are calibrated to measure on an empirical scale of
0-100 units. The different models types use different sized ball sensors
(2.5, 5 and 10 mm diameter) and are offered in flat-bottomed versions (used
on large diameter cylindrical samples) as well as models with concave-shaped
bottom surfaces for use on small-diameter cylindrical test samples.

Shore Durometers are typically used to measure the hardness of a wide
variety plastics, rubber, elastomers and similar materials. All models have a
flat bottom and differ in the shape of the sensing pin as well as the internal
spring force that resists deflection of the sensing pin. All models are calibrat­ed using standards that are specified in various Test Procedures issues by
ASTM, DIN and JIS Quality organizations worldwide.

1.1 Unpacking

Unpack the HP Durometer carefully and
inspect it for any damage. If damage is
found, contact Electromatic immediately by
telephone at 516-295-4300 or send email to
[e-mail].

1.2 Complete Kit

HP Series Durometers are supplied
as a complete kit, including:

• Durometer

• Operating manual

• Carrying case.

plastic cap

2.0 OPERATING PROCEDURES

1. Place the instrument on the material
to be tested. The durometer must be
level, and the sensing pin must be
perpendicular to the material to be
tested.

Any angle other than perpendicular
(90°) mauy cause errors

2. Holding the knurled, spring-loaded
outer shell between fingers, press
downwards until the lower edge of
the shell meets the red line marked
on the housing. This ensures that
sufficient pressure is applied as
specified in the standard. It also
ensures that the same amount of
pressure is applied from measurment
to measurement, and when the
durometer is used by different
operators.

3. Record reading after approximately
2–3 seconds. Release pressure on
the outer shell and remove the
durometer from the test material.

2.1 Memory Pointer (optional)

The Memory Pointer moves with the
measurement pointer when a measure­ment is taken. However, when pressure
on the outer shell is released, and the
measurement pointer returns to zero, the
Memory Pointer remains in position,
marking the last measurement.

To return the Memory Pointer to the
zero position prior to taking another
measurement, rotate the knurled knob
on the face of the instument counter­clockwise until the pointer has been
reset. See figure at right.

3.0 VERIFYING CALIBRAION

3.1 Textile Models (HP-2.5, HP-2.5F, HP-5, HP-5F, HP-10, HP-10F)

The Textile Durometers utilize a 0-100 units scale. The units have not formal
engineering classification and are not related to a specific Shore value or
other known value. These Textile Durometers are designed to obtain objective
comparative values that are effective for classifying the end-product quality.
Therefore, there are no standards that can be used to compare against and it is
for this reason that an NIST-Traceable Calibration Certification can not be
performed.

You can however test that the gauge is functional and un-damaged by press­ing the flat-bottomed models ("-F" models) against a smooth surface (such as
glass or marble). When fully pressed down, the dial should perform one com­plete rotation and go back to "0". When released, it should un-coil, and return
to "0" as well. If not, please contact the factory immediately.

On model with a concave base (for measurement on small bobbins or cones),
you can perform a similar "full scale" test using the optional Zero Test Block
(part number HP-TB).

1. Press the Textile Durometer
down on the test plate, which is
available as an accessory and
can be ordered under item
number HP-TB (see Fig. 1).
Do not move the spring-loaded
outer ring.

2. The scale pointer should make
one full turn on the scale, from
zero to zero, when you press
down on the instrument. If it
does not, contact Electromatic
for assistance.

NOTE: Do not loosen the holding screws of the movement under any
circumstances. Loosening these screws may alter the calibration of the
instrument.

3.2 Shore Models (HPSA, HPSB, HPSC, HPSD, HPSO, HPDO)

The Shore Durometers model are calibrated against industry standards as
specified in ASTM, DIN and JIS Test Procedures. Calibrated Test Samples
CAN NOT BE USED for verification of the calibration, as these test samples
are subject to change due to temperature, sunlight and other ambient condi­tions. Certification of the calibration is normally done at test facilities that
can independent test the internal spring forces of the Durometer and check
the travel/reading accuracy of the dial indicator.

Contact factory for the optional NIST-Traceable Calibration Certifications.

1. Press the Shore Durometer
down on a glass plate
(see Fig. 2). Do not move
the spring-loaded outer
ring.

2. The scale pointer should
make one full turn on the
scale, from zero to zero,
when you press down on
the instrument. If it does
not, contact Electromatic
for assistance.

NOTE: Do not loosen the holding screws of the movement under any
circumstances. Loosening these screws may alter the calibration of the
instrument.
