5. Non-linear output
a. Incorrect calibration
— Recalibrate unit
b. Excessive loop resistance.
— Reduce loop resistance
c. Damaged jacket on insulated probe
— Replace probe
d. Extreme material build-up on probe
— Possible misapplication; consult factory.
e. Interfering surfaces too close to probe
— Mount probe in better location;
— Use stilling well;
— Use non-metallic brackets and/or standoffs to
position flexible or extremely long rigid probes a
uniform distance from the tank wall.
f. Curved or non-parallel surfaces near probe
— Mount probe in better location;
— Use stilling well.
