DEVICE OPERATION
The PEC Flaw Detector PE4332 can operate in two modes. They are the simple
mode of thickness measurements and the scan mode.
The scan mode is used when it is necessary to test any expanded area of the
test item. In this mode, you shall apply the special grid to the test item and
sequentially save the thicknesses measured in the grid nodes in the Device memory.
When a large data array is not required and it is enough to measure only a
few test points, then you can use the simple mode of thickness measurements
instead of the scan mode.
Prior to operation beginning, select the sensor suitable for this test item.
Sensor Selection
The PEC Flaw Detector PE4332 can operate with of three sensors: either
PEC433201, PEC433202, or PEC433203. The standard scope of Device supply includes
one sensor PEC433202.
The sensor shall be selected depending on the thickness range to be tested,
insulation thickness range, as well as material of the insulation casing.
Figures 43 and 44 show a diagram for sensor selection depending on the
above parameters.
