76 CHAPTER 7 • DATA SETUP & COLLECTION˽˽˽˽Loop Size – Adjusts the size of the loops.Loop Spacing – Adjusts the loop spacing.Figure 7.4 – Loop EmulationThese settings are read by a Click contact closure device and used so that the contact closurescan be properly timed to emulate a given loop size and spacing. The loop size is alsoused by the sensor in the occupancy calculation. For example, larger loop sizes will resultin higher occupancy numbers in the interval data. However, adjusting these parameterswill not modify the reported vehicle length or speed (see the Lane Adjustment section inChapter 6 of this user guide to accomplish these tasks).Data Storage & DownloadThe Data Storage & Download window contains the following three sections (see Figure7.5):˽˽˽˽˽˽Storage Settings – Allows you to adjust the data interval length and how data is stored.Storage Status – Shows a storage timeline, the storage level and the amount of storagespace remaining.Data Download – Allows you to retrieve the data from the sensor and store it in reportformat to a laptop or handheld computer.
