Flashing Error Message: Our volumetric flow meters and controllers display an error message

(VOV = volumetric overrange) when a measured parameter exceeds the range of the sensors in the

device. When any item flashes on the display, the flashing parameter is not accurate. Reducing the

value of the flashing parameter to within specified limits will return the unit to normal operation and

accuracy.
