Coarse Tuning And Fine Tuning Of Vertical Deflection Coefficient; Setup Of Reverse Phase Of Vertical Channel - UNI-T UTD2025C Operating Manual

Operating Manual for UTD2000/3000
4. Regulation setup of vertical volt/grid
Volt/grid scope is 2mV/div
V/div (or 10V/div), or 1mV/div
by way of 1 2 5 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.
