OPERATING INSTRUCTIONS Calculate the voltage according to the equation below. G E N E R A L METHODS OF OPERATION Voltage = Amplitude x sensitivity A waveform to be viewed is fed to V . I N P U T terminals (1) an alternative, the voltage can be obtained by a and G N D (2) or (2) and D C terminal ( 3 ) .
