Introduction 35ScaleAny changes you make in terms of rescaling (either horizontal or vertical) will only affect the way data is displayed,and will not change the basic characteristics of your data file. Horizontal scale options affect all channels; verticalscale options can be set independently for each channel.Horizontal scale runs along the bottom of the display window and is where the numerical units are listed. You mayshow/hide the scale via the Show>X-scale command. The default setting uses four divisions (vertical lines) perscreen. You can change the horizontal scale setting to control the amount of data that appears on the screen at anygiven time. See page 636 for details.Vertical scale runs along the right edge of the display and controls the range of amplitude values displayed foreach waveform. You may show/hide the scale via the Show>Y-scale command. You can set the scale midpoint (thevalue that appears in the center of the vertical scale) for each channel. When multiple channels are displayed, thickhorizontal lines separate each waveform into its own vertical “track.”As with the horizontal scale, there are four divisions on the vertical axis, and the display range will equal the Scalevalue x 4. If Scale is set to 3 mVolts per division, 12 mVolts of data will be displayed. You can use the RangeGuide as a visual aid to establish the proper Gain.Note:The Scale Precision setting only applies to the Scale. You must set measurement result precisionseparately.
