Instructions for Use
8.1
Single Coil Probe
1. Connect the ECP to the flaw detector using a connecting cable.
2. Set the ECP frequency in a range specified in the registration certificate for the ECP.
3. Set the ECP drive not more than 2 V.
4. Press
key to select the capacity.
5. Place the ECP to the flaw-free area of a calibration block.
6. Press
key to balance the ECP.
7. Put a signal from a lift-off in the horizontal plane. For this, it is necessary to decline the ECP
from the vertical axis at an angle of 15-
45 ˚. While the vector end is deviated, press
key. In
case, if the first attempt to put the signal from the lift-off horizontally failed it is necessary to
repeat the steps described above, or put the lift-off signal manually using the phase change (
parameter). The signal from a defect should be appeared in the first or second quadrant
of the complex plane.
8. By increasing the gain on preamplifier
and amplifier
you should maximize the
signal amplitude, but at the same time monitor behind parameters of the input circuit.
9. After changing any parameter that affects the absolute value of the signal it is necessary to
perform balancing by pressing
key.
10. While testing aluminium alloys it is recommended to use the vertical gain "
V GAIN" for
the visual spread of signals from the distortion and signals from a defect in a phase.
11. Select the required type of a threshold level.
12. Move the probe across the artificial defect at calibration block for several times and visually
set up the ALARM relative to the signal from the defect. After the ALARM was properly set up,
the light alarm while detecting the defect will be triggered on the flaw detector keypad (digital
indicators on the display) and sound alarm (if it has not been turned off in "SETTINGS" menu).
8.2
Reflection, Differential Probe
1 Connect the ECP to the flaw detector using a connecting cable.
2 Set the ECP frequency in a range specified in the registration certificate for the ECP.
3 Set the ECP drive not more than recommended in a registration certificate for the ECP.
4 Place the ECP to the flaw-free area of a calibration block.
5 Press
key to balance the ECP.
6 It is recommended, the signal from the defect to be placed in the first or second quadrant of
the complex plane. To correct the ECP phase use
parameter.
7 Increasing the gain on preamplifier
and amplifier
you should maximize the signal
amplitude, but at the same monitor behind parameters of the input circuit.
