Chapter 4. Error Codes
4.2.4 Err 3: Velocity Range
Problem: The velocity exceeds the limits programmed in the New Meter Browser information setup (see Chapter 2,
Initial Setup ).
Cause: This error may be caused by the entry of improper programming data or by poor flow conditions and/or
excessive turbulence.
Action: Make sure the actual flow rate is within the programmed limits. See Chapter 2, Initial Setup for details.
Refer to Chapter 5, Diagnostics , to correct any flowcell and/or transducer problems.
4.2.5 Err 4: Signal Quality
Problem: The signal quality is outside the limits programmed in the New Meter Browser information setup (see
Chapter 2, Initial Setup ).
Cause: The peak of the upstream or downstream correlation signals has fallen below the correlation peak limit,
as set in the New Meter Browser information setup. This may be caused by a flowcell or electrical
problem.
Action: Check for sources of electrical interference and verify the integrity of the electronics console by
temporarily substituting a test flowcell that is known to be good. Check the transducers and relocate
them, if necessary. See Chapter 5, Diagnostics , for instructions.
4.2.6 Err 5: Amplitude Error
Problem: The signal amplitude exceeds the limits programmed in the New Meter Browser information setup (see
Chapter 2, Initial Setup ).
Cause: Solid or liquid particulates may be present in the flowcell. Poor coupling for clamp-on transducers.
Action: Refer to Chapter 5, Diagnostics , to correct any flowcell problems.
4.2.7 Err 6: Cycle Skip, Accel.
Problem: The acceleration exceeds the limits programmed in the New Meter Browser information setup (see
Chapter 2, Initial Setup ).
Cause: This condition is usually caused by poor flow conditions or improper transducer alignment.
Action: Refer to Chapter 5, Diagnostics , to correct any flowcell and/or transducer problems.
