Measurement Difficulties 

If a measurement difficulty occurs for greater than the Failsafe Timer (P070) setting, "LOE" 
is flashed alternately with the Reading display. Under certain conditions, a measurement 
difficulty may cause the XPL Plus to "lock on" to a false echo and report a fixed or wrong 
Reading. 

Flashing "LOE" Display 

If "LOE" is displayed, ensure the following: 

1. Material (object) surface monitored is within the maximum range of the 

transducer. 

2. Transducer (P004) value matches the transducer used. 
3. Transducer is located and aimed properly. 

(See the Transducer manual for the maximum range, mounting and rough aiming 
instructions.) 

For optimum performance, adjust the transducer aiming while monitoring the Echo 
Confidence (P805) for various material levels over the measurement range. When 
complete, set the transducer aiming at the best angle for all levels. 

To display Echo Confidence in the RUN mode 

Press 

 and hold for 4 seconds (Failsafe Time Left changes to the Short:Long 

Confidence display). 

To display Echo Confidence in the PROGRAM mode, access the Echo Confidence (P805) 
parameter. To update the value displayed after each aiming adjustment 

Press 

 (5 times or more to verify stability) 

If the condition persists (despite optimum aiming), optimize transducer performance. 
Adjust Short Shot Frequency, (P842) and Long Shot Frequency, (P843) for maximum Echo 
Confidence (P805). 

Increase the Failsafe Timer (P070) value, if failsafe operation will not be compromised by 
the larger value. 

If "LOE" is displayed only when a sloped bottom vessel is near Empty, the echo is probably 
being reflected away from the transducer. Install an empty "target plate" in the bottom of 
the vessel. When exposed (not covered by material), the target plate provides the 
reflective surface representative of an empty vessel. 

Install a longer range transducer, enter the new Empty (P006) distance, and (if necessary) 
optimize aiming and frequency again. 

If a longer range transducer is not available, connect an oscilloscope to the XPL Plus (see 
Enhancement Parameters Scope Displays, P810). 

If a discernible echo is observed (representative of the material / object surface), reduce 
the Confidence Threshold (P804) while taking new measurements (in the RUN or 
PROGRAM mode).
