Error Codes
E2: Sound Speed Error
Problem:
The sound speed exceeds the limits programmed in the
SETUP-SIGNL
submenu of the
User Program
.
Cause:
The error may be caused by incorrect programming, poor
flow conditions or poor transducer orientation.
Action:
Compare the measured sound speed to tabulated nominal
values for the fluid being used and correct any
programming errors (see page 2-13). Refer to Chapter 6,
, to correct any flowcell and/or transducer
problems.
E3: Velocity Range
Problem:
The velocity exceeds the limits programmed in the
SETUP-SIGNL
submenu of the
User Program
.
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. Also, check the value entered into the
SETUP-
SIGNL
submenu, as described on page 2-13. Refer to
, to correct any flowcell and/or
transducer problems.
E4: Signal Quality
Problem:
The signal quality is outside the limits programmed in the
SETUP-SIGNL
submenu of the
User Program
.
Cause:
The peak of the upstream or downstream correlation
signals has fallen below the correlation peak limit, as set
in the
SETUP-SIGNL
submenu. 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 6,
, for instructions.
E5: Amplitude Error
Problem:
The signal amplitude exceeds the limits programmed in
the
SETUP-SIGNL
submenu of the
User Program
.
Cause:
Solid or gas particulates may be present in the flowcell.
Poor coupling for clamp-on transducers.
Action:
Refer to Chapter 6,
, to correct any flowcell
problems.
