To simplify interpretation, the instrument features a split-screen or full-screen galvanometer display mode.
Automatic Lift Off compensation is a function that compensates the gain so that the same defect is visualized in the same way (identical amplitude) despite a difference in paint thickness.
This function displays a previously saved signal on the screen at the same time as the operator is controlling. This enables signal comparison.
Many aeronautical procedures require conductivity monitoring.
WeldCheck 3 automatically switches to this mode when the conductivity probe is connected, and returns to fault-finding mode when it is disconnected.
With different settings on the same probe, it is possible to subtract (mix) part of the unwanted signal. For example, a plate signal during a tube inspection. It is also possible to control two probes with two separate settings. Easy to use, with a menu for each channel:
- red for channel 1
- blue for channel 2
- green for the mixing channel
