GENERAL OPERATING INSTRUCTIONS
The following procedures are based on ASTM Standard D2240. This standard is recognized as being definitive, however, not all applications require such stringent controls.
Readings below 10/A may be inexact and should not be reported. Readings above 90/A may be inexact and should be made on a Type D durometer. Readings below 10/D should be made on a Type A durometer.
The surface of the sample to be tested shall be clean and smooth. The sample should be at least 1/4" (6 mm) in thickness unless it is known that identical results are obtained with a thinner specimen. Thinner materials can be stacked to obtain the minimum thickness (DO NOT GLUE). Such results may not agree with those of a solid specimen. Most materials above 50/D can be tested with a 1/8" (3 mm) minimum thickness. The sample should be large enough so that the indenter is at least 1/2" (12 mm) from any edge unless it is known that identical results are obtained when measurements are made closer to the edge. The surface of the specimen shall be flat over a sufficient area to permit the presser foot to contact the specimen over an area having a radius of at least 1/4" from the indenter point. The temperature of the specimen should be 73.4°F ±3.5°F (23°C ±2°C). The specimen should be allowed to rest at this temperature for at least 1 hour prior to testing, as the properties of most materials change with temperature.
Place the specimen on a hard, horizontal surface. With the durometer held vertically, press and hold release the 'ON/clr' button to turn on the digital indicator. If desired, press and release the 'HOLD' buton to enable max-hold. Hold the durometer vertically with the point of the indenter at least 1/2 " from any edge. Apply the presser foot to the specimen as rapidly as possible, without shock, keeping the foot parallel to the surface of the specimen. Apply just sufficient force to obtain firm contact between the presser foot and the specimen. Hold for 1 or 2 seconds, the maximum reading can be obtained by a setting on the indicator (see above). When max-hold is enabled the maximum value reached will automatically be displaced and held until reset. To disengage the maximum feature, press and release 'HOLD' button again. If other than a maximum reading is needed, hold the durometer in place without motion and obtain the reading after the required time interval. Make 5 tests at least 1/4" apart and use the average value.
Press and hold ON/CLR until indicator turns on.
Press the 2ND button until 2ND appears on the display. Press the OFF/MODE.
An hour glass appears at left side of display if AUTO OFF is active. If AUTO OFF is active the indicator will power off in 10 minutes with no activity (button press or spindle movement).
Allows you to hold the value on the display according to the specified mode.
Press HOLD to toggle hold mode on and off.
MAX - Holds and displays the highest reading attained.
MIN - Holds and displays the lowest reading attained.
FRZ - Holds and displays the reading displayed when HOLD is engaged.
Note: Pressing ON/CLR button resets indicator to spindle position except in FRZ; resets to zero.
Reset to Factory Default
This will set all features and functions back to the factory default settings.
Press the 2ND button (2ND icon should appear on the display), followed by ON/CLR, then press IN/MM.
Note: Factory defaults cannot be reset if the LOCK feature is on.
For a complete calibration check of mainspring, and visual and mechanical check of indenter, the instrument should be returned to PTC® (see Guarantee & Calibration Service) or refer to ASTM D2240 Specifications. PTC® recommends the unit be returned at least every 12 months for this check. For a quick field check, follow the guideline below. Under no circumstance should a test block be used as a standard to calibrate a durometer.
1. The pointer should read zero when no force is applied to the indenter of the durometer.
2. Hand hold the durometer and insert the indenter into the hole of the calibrated test block. Apply enough force to make firm contact between the top surface of the test block and the presser foot. The dial reading should agree with the value stamped on the check block (±1). Several tests should be made and the results averaged.
3. The indenter must protrude 0.098 to 0.100 inches below the presser foot.
4. When the indenter is fully displaced, the durometer should read 100 points. Use care as to not damage the tip of the indenter.
