Front Cover Removal
Remove the front cover by grasping its left and right edges and snapping it
off of the front subpanel. (When reinstalling, align and snap back on.)
Power On
1. Check that the rearĆpanel principal power switch is on (see Figure 1Ć1).
The principal power switch controls all AC power to the instrument.
2. If the oscilloscope is not powered on (the screen is blank), push the
frontĆpanel ON/STBY button to toggle it on (see Figure 1Ć2).
The ON/STBY button controls power to most of the instrument circuits.
Power continues to go to certain parts even when this switch is set to
STBY.
Once the digitizing oscilloscope is installed, it is typical to leave the
principal power switch on and use the ON/STBY button as the power
switch.
