Page 7: Measurement Principle
4. Measurement Principle Static friction is generally measured using the incline method. As illustrated in Diagram 1 below, when an object of weight W is placed upon a surface which is gradually inclined at an increasing angle, at some angle of inclination the acceleration of gravity acting upon the object will exceed the static friction which tends to keep the object in place and the object will begin to slip. -
Page 8: The Vcm Principle
5. The VCM Principle The VCM (voice coil motor) operating principle is an application of Fleming's left hand rule. As illustrated in the diagram below, the VCM is composed of a magnetic circuit and coil assembly. When a current passes through the coil placed in the magnetic field, the current, magnetic field and force move at right angles to each other. -
Page 9: Using The Portable Friction Meter
6. Using the Portable Friction Meter 1. Attach a Sample The coefficient of friction between to samples can be measured either by attaching the samples to the slider with two-sided tape or by fixing the samples in place using the O ring supplied attached to the slider. ●... - Page 10 3. Check the Power Supply Voltage After turning on the power, check to make sure that the LED display reads "0.000". The batteries need to be replaced if the LED display reads "Lo" or "8.888". To replace the batteries, use the supplied screwdriver to remove the screws which hold the battery case cover in place.

Page 11: Notes Regarding Use
7. Notes regarding use 1. Precautions on main unit ● Do not drop or give a strong impact to the unit. Failure to observe this may cause a malfunction because this product has a precise structure. ● Do not attempt to disassemble or modify the unit. Failure to observe this may cause a malfunction because the sensor section and VCM section of this product have a precise structure. - Page 12 3. Precautions on sample ● Be careful about the sample surface. If the sample surface has unevenness or wrinkles, measurement results may be affected. If there is a burr on the surface, it is caught and correct data cannot be obtained. Pay attention when processing or putting a sample.

8. Technical information 1. Characteristics and Performance ● Driving force generated by VCM calculated using a strain gauge (Actual measurement example) ● VCM driving force constant calculated using a strain gauge (Actual measurement example) ● Calculation error due to circuit resolution. - Page 14 2. Selection of slider Slider selection is significantly important for measuring a coefficient of friction. The measurement results may be completely opposite depending on sliders. For example, the coefficient of friction on a rough surface is generally larger than that on a smooth surface. When measurement is conducted with the use of the standard slider, however, the measurement result may be reversed.
