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).
8.3
ROTATION PROBE
8.3.1
Connect the rotary scanner to the flaw detector using the
connection cable.
8.3.2
Connect the ECP to the rotary scanner. Approximate marks on the
case of the probe and scanner should coincide.
8.3.3
Without applying excessive force insert the ECP in the scanner. In
case, when carrying out the connection you felt that the mating connectors
have rested at each other, but the marks on the cases match, you must slightly
decline the ECP from the vertical axis and insert the ECP until it stops. When
the ECP is properly installed in the scanner, the rubber o-rings should not be
seen.
8.3.4
Set the ECP frequency in a range specified in the registration
certificate for the ECP.
8.3.5
Set the ECP drive not more than recommended in a registration
certificate for the ECP.
8.3.6
At "ROT PRESENT" position, set up "On". In displayed menu
choose the type of the rotary scanner and press
key.
8.3.7
At "RРМ" position, firstly set the min rounds – 600.
8.3.8
Press the switched on button on the case of the rotary scanner.
The ECP should be in the air.
8.3.9
To set the scanner rounds properly, press
key and wait for
the end of the procedure.
8.3.10
Press the switched on button of the rotary scanner.
8.3.11
Set the required rounds for the scanner.
8.3.12
Put the ECP into the hole of the calibration block.
8.3.13
Press the switched on button on the case of the rotary scanner.
8.3.14
Press
key to balance the ECP.
8.3.15
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.
8.3.16
Increasing the gain on preamplifier and amplifier maximize
the signal amplitude, but at the same monitor behind parameters of the input
circuit.
8.3.17
After changing any parameter that affects the absolute value of
the signal it is necessary to perform balancing by pressing
key.
