The device consists of the processing unit (4) and probe (10) connected via socket (7). The socket
for probes (7) is located on the top part of the body. The keyboard (3) is located on the front panel, as
well as the graphic display (2). The battery compartment (5) is located in the back lower part of the
device, and the batteries themselves.
The keyboard buttons and their functions
– turning on and off / left functional button;
– right functional button;
– navigation up in the device menu/selection of the measuring unit;
– navigation down in the device menu/selection of dimensions of the measuring unit;
– selection of operating mode;
– the probe zeroing.

1.6 Design and functioning

The device functioning depends on the probe used.
When the parametric probe is used (NF, M, DSH), the functioning is based on the measurement of
the generator that includes the coil of eddy current parametric probe. The generation frequency depends
on the coating thickness. The measured frequency is converted into the thickness value and shown on
the graphic display.
When the induction probe is used (F), the current impulse is generated in the primary coil of the
probe by the command from the controller. The electromotive force (EMF) is generated on the secondary
