attenuation coefficient setup of probe. Probe
coefficient in channel menu shall be set to 10× if
probe attenuation coefficient is 10:1. It has to
analogize to guarantee correct voltage
.
Volt/grid gears of vertical deflection coefficient can
be divided into coarse tuning and fine tuning
.
Please refer to following figure for setup and
