Page 4: Introduction
1. INTRODUCTION Application The VF05 two-wire guided microwave level transmitter measures the distance to the surface of liquids, solids and granules, from which the device calculates and transmits the level, volume, or weight values as required. The device can be used in storage and reaction tanks, rigid pipelines of suitable diameter and level reference vessels. The device can also be used with HART®...

5. PROGRAMMING There are two ways to program the VF05. − Programming with the HyView software − Programming with the VGF-DISPLAY unit 5.1. P ROGRAMMING WITH 5.1.1. Installing and Running HyView The “HyView HART Configuration Software” (hereafter HyView) does not require installation, however prior to running the application, we recommend installing the FTDI Driver (Virtual COM-PORT), available to download from the website of FTDI (http://www.ftdichip.com/Drivers/VCP.htm).

Page 30 5.1.2.7 Setting Up and Filling the OC (Output Conversion) Table This feature is required to create a level / volume conversion table of up to twenty points. Each new value entered must be greater than the previous one. The length and volume units can be changed later without changing the data in the table (length unit, volume unit). The Source column contains the measurement values and the Output column contains the required calibrated or calculated values.

The device continues measuring while the menu is accessed. Changes made in the menu take effect when you exit the menu. • If you do not exit the VF05 menu, the device will automatically return to the measurement display state after 30 minutes. In this case, any changes made in the menu will be ignored.
