1.  Preparation of the Instrument for Operation 

The instrument preparation procedure is specified in section “Instrument preparation for 
AFM modes” (see 

Performing Measurements

, chapter 3). The list of the basic operations is 

given below together with the description of the features of preparing the instrument for 
AFAM measurements:  

 

Electromechanical configuration for “Scanning by probe” excluding the installation of 
the sample holder. 

 

Ultrasound Transducer Installation (see i. 

1.1

on page 

6

). 

 

Fixing the Sample (see i. 

1.2

 on page 

6

). 

 

Turning on the instrument. 

 

Loading scanner calibration parameters. 

 

Preparing the measuring head (see i. “Preparing the instrument for ‘Scanning-by-
probe’ configuration” in 

Performing Measurements

): 

-

 

Probe installation; 

-

 

Adjustment of the  system for detecting the cantilever deflections; 

-

 

Installation of the scanning measuring head. 

 

Protective hood installation. 

 

Turning on the Vibration Isolation System (see the manual on the Vibration Isolation 
System).
