Chapter 13: Link and the CBLàCBR Application 271 INTRVL (SEC) INTRVL (SEC) specifies the interval in seconds between each data sample that is collected. For example, if you want to collect 99 samples and INTRVL=1, it takes 99 seconds to finish data collection. Enter values using the number keys. See the CBR or CBL 2/CBL guidebook for more information about interval limits. UNITS The results are displayed according to the UNITS specified. To specify a unit measurement (Temp or Sonic only), highlight the one you want using the cursor keys, and then press b. PLOT You can specify whether you want the calculator to collect realtime (RealTme) samples, which means that the calculator graphs data points immediately as they are being collected, or you can wait and show the graph only after all data points have been collected (End). Highlight the option you want with the cursor keys, and then press b. Ymin and Ymax To specify Ymin and Ymax values for the final graph, press ' to view the PLOT WINDOW screen. Use $ and # to move between options. Enter Ymin and Ymax using the number keys. Press - l to return to the DATA LOGGER options screen. DIRECTNS (Directions) If DIRECTNS=On, the calculator displays step-by-step directions on the screen, which help you set up and run the data collection. To select On or Off, highlight the one you want with the cursor keys, and then press b. With the Sonic data collection probe, if DIRECTNS=On, the calculator displays a menu screen before starting the application asking you to select 1:CBL or 2:CBR. This ensures that you get the appropriate directions. Press 1 to specify CBL or 2 to specify CBR.
