Real Time Status

Meter View

The Meter View shown in Figure 1, is activated by clicking the RealTime Status icon in the NanoScope toolbar. This displays the photodetector signal, RMS amplitude, horizontal and vertical deflection signals, and the signal sum when you are not engaged.

Photodetector Signal—Red dot that corresponds to the positioning of the laser on the photodetector. Signal Sum—Horizontal meter that displays the sum of the voltage response from the laser in all 4 sections of the photodetector. Vertical Deflection—Corresponds to the voltage for vertical displacement of the laser signal. Should be “0” for centering. Horizontal Deflection—Corresponds to the voltage for the horizontal displacement of the laser signal. Should be “0” for centering. RMS Amplitude—Root mean square (RMS) signal measured at the detector (TappingMode only).

Z Position Indicator

The Z position indicator and the Step Motor control, shown on the right in Figure 1, are displayed when the probe is engaged.
