1. Targeting user-friendly （Easy menu） Operability of the SPM is a problem for stable performance operation for users. The NanoNavi II station is equipped with a measurement navigation function (Easy Menu) that enables intuitive operation based on human engineering, making the SPM more familiar to use. 2. Fine Tune Support Function •Active Q *optional function Best sensitivity adjustment by the Q value control function (Active Q) achieves high sensitivity and high resolution measurements in vacuum and liquid environments. Hard disk MFM image in a vacuum (Left: without Active Q) (Right: with Active Q) •Auto Gain Function Usually retreives at 21 bit resolution from extremely rough sample surfaces to atomic order, and exhibits A/D convertor performance in full. •High speed rectagular scan Enables changes in the scan width ratio in alignment with measurement use, and reduces meausurement time by a maximum 90%.

3. Targets improved reliability of data •Probe evaluation function Equipped with a function that evaluates the condition of a probe before and after a measurement. Able to check for worn or broken probes and aids in improving reliability of data in the SPM. （Above: new probe) (Below: worn out probe) •Surface roughness JIS standard Supports the world's first surface roughness JIS standard （JIS R 1683:2007）. Data dispersion is reduced and objective roughness measurements can be expected at a high precision. •Closed loop control *optional function Eliminates effects from non-linearity, such as hysteresis or creep, on piezoelectric elements, eabling high linearity and straightness. Accuracy rapidly improved in the measurement and process of micro sized areas. 4. For completed analysis •Plenty of graphics Abundant graphics can be selected according to use. Clearly transmits images of measurement data. （Figures are 3D graphics of cuticle of a hair). •every kind of shape analysis function All kinds of parameters required for analysis. Specific numerical values gives more persuasive power to data.
