Part A — Getting Started 67Vertical (Amplitude) axisClicking the mouse in the vertical scale area (where the amplitude of each channel is displayed)generates the Set Screen Vertical Axis dialog, where values can be entered for units per division andvertical scale offset.ScaleDetermines the limits of the viewable vertical axis scale (usually Volts). BSL PRO divides eachchannel into four vertical divisions. When data is displayed in chart mode, each “track” is dividedinto four divisions. When data is displayed in scope mode (or if there is only one channel of data)the entire screen is divided into four intervals. To increase the apparent amplitude for a givenchannel, set this value to a smaller number; entering a larger number will cause the waveform toappear to have less variability.MidpointRefers to median displayed value for a particular channel. A checkbox to the left of each of theseoptions allows you to apply these scaling options to all channels. By default, the scaling optionsyou choose will only apply to the channel indicated in the dialog. If you want to apply these to allchannels, click all the checkboxes.PrecisionControls number of decimal places following whole units appearing in the vertical axis. Can beapplied to selected or all channels.Apply to all channelsApplies settings selected in the various dialog options to all channels.BSL PRO Manual
