changing the gap between ECP and the object of testing, 3) in case of change of
electromagnetic properties of the material, etc.).
BP –band pass filter. It is used to create bandwidth of useful eddy-current
signals - signals from defects and to filter out low-frequency and high-frequency
signals from noise. It is more often used at automated or mechanized testing with a
constant ECP moving speed relative to the object of testing.
9. POSITION –spot position. Changing the position of the center of the
complex plane on the screen of the flaw detector. It is used to increase the usable
space on the screen of the flaw detector.
Can be set in the following positions: –complex plane center, –in the
right center of the screen, –in the right upper corner, –in the upper center
of the screen, –in the left upper corner, –in the left center of the screen,
–in the left bottom corner, –in the bottom center of the screen,
–in the right bottom corner, –per-channel display when operating in double
frequency mode.
10. GRID –grid. Different types of the screen markup to improve the visual
analysis of signals.
11. AXIS –axis. On / off position of the display of coordinate axes on the
screen of the flaw detector.
12. ALARM –activation and setting of frames (threshold levels). Types of
frames: –frames are switched off, –circle frame type, –threshold frame
type, –sector frame type, –trapezium frame type.
13. SWEEP –number of points in a screen scan.
14. PROBE –type of connector.
Single (Lemo 00) –for connection and operation with single coil probe.
Refl (Lemo 16) –for connection and operation with Reflection type probe.
Bridge (Lemo 16) –for connection and operation with Bridge type probes.
15. RPM –rounds per minute for the eddy current rotary scanner.
16. ROT PRESENT –type of connected rotary eddy current scanner.
17. Parameters of the occupancy of the input circuit.
Parameter "T: …/…/..." shows:
1) The value of a signal amplitude at the input of the receiving circuit
expressed in % of the maximum possible;
2) Input circuit is not balanced, after performing the balancing in %.
Current value of the occupancy of the input circuit expressed in % of the
maximum possible.
