５ MEASUREMENT OPERATION
• Q Factor/Peak Fr
When you have performed a frequency scan, if the resonance frequency
frequency) of the cantilever and Q factor are detected, each detected value will
appear here.
• RMS Value/Ph
The outputs of the present RMS and phase signals will appear. The displayed values
are the s
• Tuning
The parameters in the Tuning frame are used for searching for the resonance
frequency of the cantilever.
• Start
• Stop Frequency/k
• Phase Display
• Normal Scan/Autotune/Repeat Scan
When Normal Scan is selected:
When Autotune is select
When Repeat Scan is selected:
• Scan
• OSC Control
Specify the oscillation signal to the cantilever.
• Frequency/kHz

Frequency/kHz
Specify the start frequency

Specify the stop frequency of the frequency sweep in this input box.
Checking th e Phase Display check box acquires and displays phase data during
frequency scanning.
Click ing on the Scan button performs one frequency sweep from the start fre-
quency to the stop frequency. The detected peak frequency and the Q value
appear after measurement.
ed:
Select this button when you control and adjust the Q value using the optional Q
controller (TM − 26060).
Clicking on the Scan button performs frequency sweep repeatedly from the
start frequency to the stop frequency. Detected peak frequency and the Q value
appear at the end of every scan. Adjust the Q controller by referring to the
change of Q values. The scan finishes by pressing the ESC key on the key-
board.
Clicking on the Scan button starts the automatic adjusting sequence.
Starts frequency scan using the method selected from the above scan types.
Specify the oscillation signal in this input box. The range in which you can se-
lect the frequency is between 1 and 1000 kHz. The output signal is a sine wave.
Specify voltage applied to the piezoelectric element for oscillation. The voltage
depends on the value set to OSC High Output.
