Possible Cause of Error Code
1. The flow sensor may have been damaged.
This can be caused by water hammer or excessive velocity.
Solution:

Go to the Low/High Sub-Menu (See Table 8) button, and check the highest velocity
recorded.

The max velocity spec is 30 fps for a liquid; 300 fps for a gas. If these velocities
have been exceeded, the sensor may have been damaged.

Pull the meter and check for visible damage.
