Available Models

General information on textile durometers
The principle used to measure the “firmness” or “hardness” of textile material is based on measuring the resistance force of the penetration of a ball sensor into a bobbin under a constant spring load. This principle is based on the Shore hardness test procedure.
The display range of the textile durometers covers a range from 0 to 100 units, where 0 corresponds to the minimum and 100 to the maximum hardness value. These units have no formal industry standards or engineering classification, and are not related to a specific Shore value or other known value.
Since there are no international standards that can be used to compare against, we have developed a special test procedure for verifying calibration (see Chapter 3.2).

Operating Procedure

3.1 Notices Before Starting Measurement

Have you read and understood the Operating Instructions, in particular Chapter 1 „Basic Safety Notices“ ?
You are not permitted to operate the instrument before doing so.
Before working with the instrument you must put on your personal protective clothing, if necessary. For example, eye protectors, gloves, etc.

3.2 Measuring with the Durometer
General information:
Each test sample has to be tested in at least three different points.
The hardness reading must be recorded 3 seconds after pressing down the knurled outer shell.
The durometer has two movable markers that can be rotated around the faceplate to mark any desired measuring range within the display range.

Measurement procedure:

• Place the instrument on the material to be tested. The durometer must be level, and the sensing pin must be perpendicular to the bobbin axis.
  Any angle other than perpendicular may cause error.

• 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 the same amount of pressure is applied from measurement to measurement and prevents measuring errors.

• Record the reading after approx. 3 seconds. The hardness scale covers a range from 0 to 100, where 0 corresponds to the minimum and 100 to the maximum hardness value.

Each test sample has to be tested in at least three different points.

3.3 Verification of Calibration
You can test that the instrument is functional and undamaged by pressing the flat-bottomed models (“-F” models) against a smooth, level surface (such as glass or marble). When fully pressed down, the scale pointer should make one full turn on the scale, from zero to zero. The scale pointer should return to the initial zero position when you release pressure. If it does not, return the instrument to the manufacturer for servicing. On models with a concave base (for measuring bobbins, etc.) you can perform a similar “full scale” test using the optional Zero Test Block (part number HP-PT).
Optional calibration certification must be ordered separately, prior to delivery of the instrument. Subsequent calibration is only possible at the manufacturer’s facilities.

3.3.1 Verify calibration of durometer models: HP-2.5, HP-5 and HP-10
(with concave-shaped base)
– Press the durometer down on the optional Zero Test Block (HP-PT) (fig. 3.3.1).
Do not move the spring-loaded outer shell.
The scale pointer should make one full turn on the scale, from zero to zero.
If the result of verification is positive, the durometer should show correct readings.

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

3.3.2 Verify calibration of durometer models: HP-2.5-F, HP-5-F and HP-10-F
(with flat base)
– Press the durometer down on a glass plate (fig. 3.3.2).
Do not move the spring-loaded outer shell.
The scale pointer should make one full turn on the scale, from zero to zero.
If the result of verification is positive, the durometer should show correct readings.

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

Optional Accessories

Memory Pointer (Option Code M)

The durometer is available with a memory pointer which can be ordered under option code M. The memory pointer moves with the scale pointer when a measurement is taken. However, when pressure on the outer shell is released, and the scale pointer returns to zero, the memory pointer remains in position, marking the highest reading (PEAK) of the measurement.
Before beginning a new measurement:
– Rotate the knurled knob to reset the memory pointer to the zero position.

Service and Maintenance

The tension meter is easy to maintain. Depending on operating time and load, the tension meter should be checked according to the locally valid regulations and conditions (as described in Chapter 3.3). The use of other test methods than the procedure described in Chapter 3.3 may cause deviating measuring results.

Cleaning

For cleaning the unit, do not use any
AGGRESSIVE SOLVENTS
such as trichloroethylene or similar chemicals.
NO WARRANTY OR LIABILITY
**** shall be accepted for damage resulting from improper cleaning.

Verification Intervals

The question of finding the right frequency of calibration accuracy verification depends on several different factors:
→ Operating time and load of the SCHMIDT hardness tester
→ Tolerance band defined by the customer
→ Changes of the tolerance band compared to previous verifications of calibration
Therefore, the interval between verifications must be determined by the users Quality Assurance Department based on the users experience.
Assuming normal operating time and load as well as careful handling of the hardness tester, we recommend a verification interval of 1 year.

Correspondence

Should you have any questions regarding the tension meter or Operating Instructions, or their use, please indicate above all the following details which are given on the ID plate:

1. The tension meter model
2. The serial number

Repairs

Shipping instructions:
We kindly ask for return free of charge for us, if possible by airmail parcel. All occurring charges, if any (such as freight, customs clearance, duty, etc.) will be billed to customer.
For return from foreign countries, we ask you to include a proforma invoice with a low value for customs clearance only, e.g. 50 Euro, each and to advise the shipment in advance by fax or eMail.
** To avoid unnecessary follow-up questions, and the resulting loss of time or possible misunderstandings, please return the tension meter with a detailed fault description to our service department. Please indicate in your order whether  you require an calibration certificate with calibration report.
