Table 2 Status bar indicators Indicator Description Time and Date Shows the current time and date. Shows when a USB cable is connected. If a USB cable is connected and this indicator does not show in the status bar, the USB cable is not fully engaged. Make sure that the USB cable is pushed in completely and makes full contact with the connection port. - Page 18 Option Description Setup Allows the user to modify the main filter parameters and enable and program the Maximum Depth sensor positioning feature. The Maximum depth feature allows a user to enter system parameters for depth measurement in Real Time mode. The user can choose to enter a maximum depth value taken directly with a ruler measurement (manual), or taken indirectly with the depth measurement (automatic).

- Page 20 Option Description Filter Applies a data acquisition filter (Main filter or Pre-filter). The user can select the filter parameters parameters. Main filter • Fixed Period Averaging (FPA)—Fixed Period Averaging averages data over a user selectable fixed period of time (1 to 480 seconds). The default is 30 seconds. If the FPA value is 5, the velocity value shown in the display is updated once every 5 seconds.

Option Description Station entry • Fixed—The operator puts in the width of the stream and the number of stations for measurements. The meter divides the cross-section into evenly spaced distances between the station verticals. • Non-fixed (default)—The operator selects the spacing between station verticals. This is the more commonly used option as it lets the operator include obstructions and other restrictions in the cross section. -
Page 22: Operation
Operation Stream profiles Stations and station spacing For a well-chosen cross-section, division into 25 to 30 partial sections is typically sufficient. If the cross-section is very smooth and the velocity distribution very consistent, it is possible to decrease the number of stations. Make the distance between the partial stations so that no individual station contains more than 10% of the discharge. -

With the Mid- section method, the segments are not between verticals but are defined by half of the distance to neighbor verticals in each case.

Figure 17 Typical profile 1 Depth 2 Velocity Site selection A site with the typical profile shape gives the most accurate results. Visual inspection is typically sufficient to identify problem sites. Use the information in these guidelines to help select the best site. These guidelines apply to conduit and stream profiles. - Page 37 surface of the water, the meter sets the velocity value to zero. For a profile or real-time reading, the meter prompts the user to submerge the sensor in the water. If the specific conductivity of the water being measured is very low, adjust the threshold value for the best performance.
