Calibrating the PPMScope

 After setting up the hardware, the scope should be calibrated. To do this, follow the steps below:

• Switch coupling to AC mode on both channels
• Turn pot R24 until both channels read ground on the oscilloscope screen
• Ground both channel inputs
• Switch coupling to DC mode on both channels
• Both channels should still read ground
