4. CONTROLLING THE FLOW METER
The flow meter is controlled from a PC running "Viewer BUF-311"
program. The program is available free of charge.
The interface includes several tabs classified by their function. Con-
tents of the tabs are determined by the flow meter's operation mode. Af-
ter the flow meter is powered up, the operation mode is detected auto-
matically.
