Automatic flaw alarm by the first and second frequencies,
respectively, and by the mix of the 1st and 2nd frequencies, as well as
overloading alarm square. If ALARM triggers during testing, the signal
amplitude and phase are automatically measured and the signal is evaluated
by the calibration curve.

1PURPOSE
1.1 The flaw detector is intended for manual and mechanized testing by
eddy current method for the presence of surface and subsurface defects, such
as material discontinuity (cracks, laps, cissings, fine cracks etc.), for
conductivity and thickness measuring.
1.2 The flaw detector can be applied for the testing of products during
their manufacture and operation by NDT services and laboratories of
enterprises that provide the products quality control.
1.3 The parameters of testing objects, which limit the flaw detector
application area, are specified in regulatory documents for a specific type of
testing products and materials.
1.4 The flaw detector provides the possibility of connecting and
operating ECP of the following types:
- differential ECP;
- differential ECP, connected by the bridge circuit;
- differential transformer ECP with center-point earth;
- differential transformer ECP;
- single (parametric) ECP;
- single transformer ECP.
1.5 Operating and ambient temperature range is from minus 20 °С to
