The value fluc-
tuates.
Is there mutual interfer-
ence?
• Shield the other transmitter laser light to prevent it
from entering the laser receiver.
• Use the interference prevention function.
"14. Interference prevention function (only for IG-
1000/1500)" (page 4-40)
Is the transmitter/receiver
correctly mounted? Mount the transmitter/receiver correctly.
"Mounting the Sensor Head" (page 2-8)
Is the mounting distance
or the distance between
the receiver and the object
too long?
Make the mounting distance or the distance between
the receiver and the object as short as possible.
"Mounting the Sensor Head" (page 2-8)
Are the output wire and
input wire short-circuited? Check the wiring.
"Sensor Amplifier Wiring" (page 2-6)
The values are
incorrect.
Is the object tilted or
located in an incorrect
position?
Adjust the object to correctly fall within the measure-
ment range.
Is the transmitter/receiver
correctly mounted? Mount the transmitter/receiver correctly.
"Mounting the Sensor Head" (page 2-8)
Is the mounting distance
or the distance between
the receiver and the object
too long?
Make the mounting distance or the distance between
the receiver and the object as short as possible.
"Mounting the Sensor Head" (page 2-8)
Is the transmitter and
receiver used in combina-
tion of the same serial
number?
Use the transmitter and receiver in combination of the
same serial number.
"Sensor Head Unit" (page 1-12)
Is dirt or dust stuck to the
laser transmitter/receiver?
• Remove the dirt or dust.
"Influence of dirt" (page 2)
• Change the measurement sensitivity.
"4-3 Setting the Measurement Sensitivity"
(page 4-44)
• Use the edge check function.
"9. Edge check function" (page 4-31)
Is dust, dirt, water or oil
stuck to the object?
• Remove the dust, dirt, water, oil, etc.
"Influence of dirt" (page 2)
• Change the measurement sensitivity.
"4-3 Setting the Measurement Sensitivity"
(page 4-44)
Does the ambient operat-
ing temperature signifi-
cantly change?
Keep the ambient operating temperature constant.
Is the zero shift function
correctly set?
Configure the settings correctly.
"3-7 Zero Shift Function (Shifting the Internal Mea-
surement Value (R.V.))" (page 3-16)
Is the shift target value set
correctly?
Is the zero shift input wire
connected correctly?
Has the standard wave-
form been registered?
Register the standard waveform.
"3-4 Registering the Standard Waveform (Gain
adjustment)" (page 3-9)
Is the calibration com-
plete correctly? Redo the calibration.
"4-5 Calibration Function" (page 4-52)
Are the output wire and
input wire short-circuited? Check the wiring.
