In Manual mode inside Advanced Settings (see § 5.3.2.1) a customisation of full scale of
voltage and current graphic is possible in order to improve the resolution on readings. In
this situation pressing arrow keys ZOOM in or ZOOM out for increase or decrease the
value of desired full scale. Press F2 key to change from current full scale to voltage full
scale. Press ESC key (or the smart icon ) to quit waveforms screens and go back to
TRMS real time values screen.
