Switching off the DGS mode | Epson USN 52R, USN 52L instruction

Operating the DGS

Switching off the DGS mode

HNote:

If the DGS function is switched on while you vary a parameter that affects the stored reference echo, or when you use another probe, the following message is displayed:

“Clear REF and confirm with HOME”

This text remains blinking on the display for a few sec- onds. If you press the F key during this time, the refer- ence echo is cleared and the DGS function is switched off.

3.4 Switching off the DGS mode

If you switch off the DGS mode, the USN 52 R option DGS automatically sets the gain to the total of refer- ence gain and incremental gain.

–Switch the DGS mode off in the DGS function:

N or O

After switching off the DGS mode, the reference echo remains stored. You can clear it by pressing M be- longing to the GAIN function.
