(1) Input vertical trigger pulse to pin V
(2) Set VD (sub-address: 00) to DC-Coupling mode (data: 80).
(3) Set V INTEGRAL CORRECTION (sub-address: 08) to center (data: 8F).
(4) Set V S CORRECTION (sub-address: 09) to center (data: A0).
(5) Measure amplitudes V
(6) Set V-RAMP to maximum and measure amplitudes V
(7) Calculate cut levels using the following formulas.
