![]() ![]() Resonant frequency of bimorphs and support (stage): approx 200 Hz.ġ All stainless steel parts of internal surfaces are 316-type non-corrosive, non-magnetic steel.Stiffness of bimorphs: approx 10 4 N/m.Maximum lateral displacement (at maximum voltage): approx ±50 µm (0.1 mm peak-to-peak).Maximum recommended applied voltage (peak to peak): ☑00 V.Mass of stage (with glass support): approx 2 gm.Resonant frequency of stage (with glass support): approx 300 Hz.Recommended range of driving frequencies: 10 -6 to 250 Hz.Maximum shear rates attainable: 10 5 s -1 in squeeze mode (higher rates attainable in shearing/sliding mode depending on the test fluid).Maximum compressive pressure previously attained (using curved surfaces of radii 0.5 2 mm and a thin layer of hard glue): 0.5 GPa (5,000 atm).Sensitivity of measuring normal and adhesion forces: 10 nN.Normal distance resolution: 0.1 nm (1 Å).This is because some properties, for example, of piezo-electric crystals, can depend not only on the temperature, but also on the humidity, time and usage (aging and previous history effects). It is also advisable to recheck some calibrations periodically. The following values are approximate, and should be calibrated for each instrument and attachment before use as described in the Users Manuals.
