(1) Probe selection and attachment 

Check  that  the  power  supply  is  off  and  then  attach  either 
the  LEP-J  or  LHP-J  probe  according  to  the  substrate  to  be 

measured (see p. 10).  

(2) Power ON  

Press the Power key. 

(3) Calibration 

Check  whether  the  measurement  target  has  already  been 

calibrated. 

If not, then perform calibration and register the 

calibration curve (application) (see p.24).  

(4) Measurement 

The  probes  are  of  the  "one-point  contact  constant-pressure 
type," whereby a constant load is applied to the tip of the probe. 
As  shown  in  the  figure  on  the  right,  hold  the  part  near  the 

measuring part and lower the probe rapidly so that the probe 
is at a right angle in relation to the measurement surface. To 

prepare for the next measurement, lift off the probe tip once at 

least 10 mm from the measurement surface.  

When  measuring  a  cylindrical  object  or  continuously 
measuring a flat surface, the use of a probe adapter allows 
stable measurement.  

Probe usage method

Probe adapter usage 
method

Attach the probe 

adapter to the 
tip of the probe 
and secure it by 
tightening the 
screw.

Rapidly lower the probe onto 
the measurement surface.
