The settable trigger area is limited by the voltage axis range
setting.
4. Move the flashing cursor to the position shown in the
figure below, and set the trigger level using the
buttons.
The RMS value is displayed on the right side of the trigger
level.
When measuring 100-Vrms (Vmax=141 V) commercial
power, if a trigger is set to occur when the voltage drops to
90 Vrms (Vmax=127 V), the trigger event occurs as shown
here. In this case, the input voltage axis range should be set
to 50 V/DIV.
