Maintenance

Lens

Dust or dirt adhering to the lens and flaws on the lens may cause incorrect measurement. When the lens is dirty, remove the adhering object from the lens using a blower for lens cleaning etc.
If dirt remains wipe the lens softy using a cotton swab or lens wiping cloth moistened with a small amount of ethyl alcohol.

Unit

When the unit is dirty, wipe it off using a cloth moistened with a small amount of ethyl alcohol.

Problems	Cause	Solution
Un measurable	The power source is not connected properly	Check the lead wires and the connection.
Un measurable	The power voltage needs to be adjusted to the 12-24 VDC range.	Check the power voltage and adjust it to be in the 12-24 VDC range.
The measured figure is odd	The lens is dirty	Refer to the lens section in the manual under "Maintenance"
	the measuring area is off center.	Aim the target which should be within the field of view area for the sensor.
	Near the object to be measured another object emitting high temperatures is affecting the temperature reading.	Block the heat source using a board, etc.
The measured figure is not stable	The sensor is vibrating.	Prevent the vibration
The measured figure is not stable	The temperature of the sensor changes suddenly.	Put the sensor aside for a while to stabilize the sensor's temperature.
