CAUTION
1.6 Preparation for Operation
■ Suppressing noise interference
Be sure to isolate the connection cable from high-voltage or power lines. If the
connection cable is placed in the same conduit as these lines, the LS-5000 series
may malfunction due to noise interference.
■ Cooling fan
Do not block the cooling fan at the bottom of the LS-5501. If the cooling fan is
blocked, the LS-5501 may overheat and malfunction.
■ Operating environments
•
Use the controller at an ambient temperature of 0°C to 45°C (32 to 113°F), No
freezing.
• Fluctuations in the ambient temperature cause measurement errors; therefore,
the ambient temperature should be kept constant. If the temperature changes
by 10°C (18°F), the LS-5000 series will take approximately 60 minutes until the
temperature distribution in the unit becomes even.
• Do not allow any substance which may refract the laser beam, such as water
and oil, to adhere to the scanning head.
* Blow dust off the protective glass using clean air. Wipe off any remaining dust
using a soft cloth moistened with alcohol.
Note 1: Measurement conditions
When the target oscillates, the measured value may fluctuate. The measurement
accuracy can be improved when the number of averaging measurements is set
higher.
Note 2: Target
When the target shape or luster varies, a measurement error may occur. In this
case, place a standard target in the measuring area and perform the calibration
using the [CALIB] key.
