1.0 Introduction The new Check-Line AD-100 analog durometer is the ideal choice for a wide range of Shore hardness measuring applications. The AD-100 displays hardness readings on an easy-to-read analog scale calibrated in 0 to 100 Shore units. Seven scales are available: A, B, C, D, DO, O, OO. The AD-100 conforms to: • ASTM D-2240 • DIN 53505 • ISO 868 • ISO 7619 1.1 Unpacking Unpack the durometer and inspect it for any shipping damage.
2.0 Testing Procedure 1. Place the instrument on the material to be tested. The AD-100 can be used at any angle, it does not need to be vertical. NOTE: If the gauge is equipped with the Memory Pointer option make sure the pointer is returned to zero before starting. 2. Press the foot of the gauge firmly against the specimen, but not so firmly as to imbed the foot into the surface of the material. 3. Maintain pressure for 2 to 3 seconds. The dial hand gives the reading in durometer points.
3.0 Memory Pointer (optional) The Memory Pointer moves with the measurement pointer when a measurement is taken. However, when pressure on the specimen 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 instrument counter- clockwise until the pointer has been reset.
