Inspecting before Measurement and Verifying Operations
Checking the impulse response waveforms
Implement impulse testing on the inspection master workpiece to check that there are no
abnormalities in the instrument or equipment. Set the test conditions according to the workpiece.
Tools to be prepared
Master workpiece (a workpiece close to the mass production master workpiece, or a coil of approx.
1 mH created using reinforced insulation wire)
Calibrate the voltage of the master workpiece beforehand and record the master waveform.
1
Connect the master workpiece to the test lead.
2
Select the table to which the master waveform was saved in test mode.
3
Implement the test.
If the waveform shape (peak voltage, zero‑cross point, etc.) changes greatly
(1)
Being affected by
residual magnetization from the workpiece core.
Apply a degaussing impulse to the workpiece until the waveform stops changing.
You can see how waveforms diverge by turning
on waveform superposition and repeating the
test multiple times.
