16.1.2.2 Using the display during remote control
You can observe the screen while a remote control script is executed. This is helpful for
program test purposes but tends to slow down the measurement. Therefore it is recom-
mended that you switch off the display in real measurement applications where a tested
program script is to be executed repeatedly.
To switch on the display, tap the "View" button in the upper left corner of the touch
