DGS mode

Overview of the DGS menu

Function group DGS mode

In the first operation level you can carry out a DGS measurement. This includes

–adjustment of the reference gain and incremental gain,

–adjustment of the recording limit,

–switching-on of the DGS mode and the DGS curve display,

–shifting of the gate to select the echo to be evaluated.
