Bydefault, this is set to “1” but may be set to any value between 1 and 8 by choosing anumber from the pull-down menu. When you change this setting, all the currentmeasurement values are cleared (set to "None"). (Note: To Show or Hide the measurementrows altogether, toggle the option in the Display > Show > Measurements menu. Seepage 7245 for more information.)Allows control of the precision with which measurements are displayed. The default is 6digits, but precision can be set to any value between 1 and 8 by choosing a number fromthe pull-down menu. This option controls the number of digits displayed right of thedecimal place for all visible measurement windows. For instance, if this value is set to 3,one measurement window might show 125.187 while another reads 0.475.When the precision is changed, the value will be rounded up or down based on the selecteddata value. The precision does not alter the data file. For example, if the selected data valueis 0.00480000, 4-digit precision will display 0.0048, 3-digit will display 0.005, and 2-digitwill display 0.00 (not 0.01 which would be a round-up from 0.005 rather than from theselected value of 0.00480000).These options control how waveforms are displayed on the screen.Allows for some (“compressed”) waveforms to be plotted in “draft” mode, which results infaster plotting time, although the display is not exact. A waveform is consideredcompressed when more than three sample points are plotted per pixel on the screen.For example, on a display that is 800 pixels wide, a compressed waveform would be any
