The configuration drop-down houses six screens used to control how the flow meter is set up and responds to varying flow
conditions. The first screen that appears after clicking the Configuration button is the Basic screen. See Figure 40 .

General
The general heading allows users to select the measurement system for meter setup, either English or metric and choose from
a number of pre-programmed small pipe configurations in the Standard Configurations drop-down. If pipe measurements
are to be entered in inches, select English. If pipe measurements are to be entered in millimeters, select Metric. If the general
entries are altered from those at instrument start-up, then press Download in the lower right-hand portion of the screen and
cycle power to the flow meter.
When using the Standard Configurations drop-down menu alternate, menu choices can be made by using the
following guidelines:
1. Select the transducer type and pipe size for the transducer to be used. The firmware will automatically enter the
appropriate values for that pipe size and type. Every entry parameter except for Units, MODBUS Address, Standard
Configurations, Frequency, Flow Direction and Specific Heat Capacity will be unavailable behind a grayed out entry box.
2. Go back to the Standard Configurations drop-down menu and select Custom. As soon as Custom is chosen, the previously
grayed out selections will become available for editing.
3. Make any changes to the basic configuration deemed necessary and press Download.
4. To ensure that the configuration changes take effect, turn the power off and then back on again to the transmitter.
Also under the General heading is a field for entering a MODBUS address. If the flow meter is to be used on a multi-drop RS485
network, it must be assigned a unique numerical address. This box allows that unique address to be chosen.
