DAMPING (Probe Matching)This function serves for matching the probe. You can use it to adjust the damping of the probe’s oscillating circuit and consequently change the height, width and resolution of the echo display

- High (100Ω), this setting reduces the echo height but mostly also produces narrow echoes with higher resolution
- Select the function DAMP, - Set the required value by means of ( Down/Up arrow ) key to the right value.
