Reading fluctuates while
material level is still (or vice
versa).
Reading is fixed, regard-
less of the actual material
level.
Material level reported is
always incorrect by the
same amount.
Measurement accuracy
improves as level nears
transducer.
Reading is erratic, with little
or no relation to material
level.
Note: Please refer to the complete Instruction Manual for further information.

Cause
No power.
Obstructed infrared interface, defec-
tive programmer.
Short circuited transducer cable, or
defective transducer at indicated ter-
minal block number.
Transducer not connected or connec-
tion reversed.
Open circuited transducer cable, or
defective transducer at indicated ter-
minal block number.
Weak or non-existent echo.
Wrong transducer selected (P004).
Transducer connected in "two wire"
method.
Transducer connected backwards.
Value too large to display in 4 or 5
characters.
Incorrect measurement stabilization.
Transducer acoustic beam obstructed,
standpipe too narrow, or transducer
ringing (reads over 100%).
Incorrect Empty (zero) reference for
level operation (P001 = 1).
Incorrect Sound Velocity used for dis-
tance calculation.
True echo too weak or wrong echo
being processed.
MultiRanger – QUICK START MANUAL
Action
Check power supply, wiring, or power
fuse.
Check programmer usage:
15 cm (6") from faceplate pointed at
upper target.
Repair or replace as necessary.
Check connection to displayed terminal
blocks
Repair or replace as necessary.
Relocate and/or re-aim transducer.
Proceed to Measurement Difficulties.
Re-enter correct transducer type.
Do not tie white and shield together, use
all three terminal blocks.
Reverse black and white wires on termi-
nal block.
Select larger Units (P005), or lower Con-
vert Reading (P061).
Alter Maximum Process Speed (P003) or
damping (P704).
Relocate and / or re-aim transducer at
material level or object.
Go to Measurement Difficulties below.

See Empty (P006), Reading Offset (P063),
Offset Calibration (P650), and Offset Cor-
rection (P652).
Use transducer with built-in temperature
sensor or a TS-3 temperature sensor.
See Sound Velocity.
Relocate and / or re-aim transducer.
Check noise parameters.
