Regulation setup of vertical volt/grid
Setup of reverse phase of waveform
Reverse phase of waveform:

Volt/grid scope is 2mV/div
V/div (or 10V/div), or 1mV/div
V/div with step
by way of 1
Deflection coefficient shall be
altered within current vertical gear scope by less
step during fine tuning so as to realize
uninterrupted and continuous adjustment of vertical
deflection coefficient within all vertical gears.
