MiniRanger Plus – INSTRUCTION MANUAL

Page 63

*refer to associated transducer manual.

Symptom

Cause

Action

...continued

Transducer location for aiming:

Poor installation
Moved my material or vibration
Flanging not level

Transducer malfunction:

Temperature too high
Physical damage
Excessive foam on liquid face

Relocate or re-aim transducer 
for maxium echo confidence, 
P805

Check P300, P805, P807
Inspect
Use foam deflector or stilling 
well or relocate

Reading does not change, but 
the level does

MiniRanger Plus processing 
wrong echo:

i.e. vessel wall, sturctural mem-

ber, stationary agitator, 
material hang-up, or rathole.

Transducer ringdown, reading 
high level

Re-aim transducer*

Check standpipe for internal 
burrs or welds

Mounting need only be hand 
tight*

Increase blaking, P800

Raise short measurement con-
fidence threshold, P804

Measurement is consistently 
off by a constant amount

Measurement offset

Refer to P650

Reading error progressively 
worsens with distance

Atmosphere other than air or 
stratified

Refer to P651

Screen Blank

Loss of Power

Check power wiring
