Strange linear output levels.
• Is the power supply device connected correctly?
• Are the Interface and Calculating Units connected
correctly?
• Are all cables connected correctly?
• Is the signal line disconnected?
This problem may be due to temperature
characteristics. Execute zero reset periodically using
the standard object to correct this problem.
• Has a timing input been made while hold is enabled
and the trigger type has been set to
?
• If the hold function is enabled and the trigger type is
[UP] or [DOWN], has the self-trigger level been set
to an appropriate Value.
• This problem may occur due to the characteristics of
the sensor. Make sure that the distance to the
sensing object is appropriate.
• This problem may be solved by selecting a fixed
measurement gain in the measurement sensitivity
setting.
The laser of the sensor head has deteriorated.
Replase the Sensor Head.
• Are all cables connected correctly?
• Is the signal line disconnected?
• Are reset inputs short-circuited?
• Is the switch on the bottom of the Amplifier Unit set
to the correct position?
• Has the correct selection (voltage/current) been
made in the monitor focus settings?
• Linear output levels can be fine-tuned.

8.Error Messages and Countermeasures
This section outlines the error messages displayed on the main display and the
countermeasures for those messages.

If this does not solve the problem, use a

・
If two Amplifier Units have been connected,
turn OFF the power supply and check that
the Amplifier and Calculating Units are
connected correctly.
・
If only one Amplifier Unit is being used,
connect another Amplifier Unit temporarily
and turn OFF the two-sensor operation,
or initialize the settings data.
・
Change the mode for the CH1 Amplifier
Unit to RUN.
・
Turn OFF the power supply and check that
the Amplifier and Calculating Units are
connected correctly. Replace the Amplifier
Unit or the Calculating Unit if the above
countermeasures do not solve the
problem.
Turn OFF the power supply, check the
connection for the Sensor Head, and then
turn ON the power supply again.
When there is a possibility of received the
influence of the noise,the power supply of
the sensor is divided with other equipment
or high-voltage lines and power lines must
be wired separately from this sensor.
If this does not solve the problem, the
Sensor Head is defective. Replace the
Sensor Head.
Turn OFF the power supply, check the
wiring for the Amplifier unit, and then turn
ON the power supply again. If this does
not solve the problem, the amplifier unit is
defective. Replace the Amplifier unit.
Turn OFF the power supply, check that the
HIGH, PASS, and LOW output lines are
not short-circuited, then turn ON the
power supply again.
When the mutual interference
prevention setting is ON or
2-sensor operation setting is
ON, but only one Amplifier
