• Handle the Sensor Section with Care
Never strike the sensor section against the measurement surface or slide the unit when the sensor is pressed
against the measurement surface. Also, accurate measurement may not be possible if the sensor section is dirty.
• Caring for the LZ-990 Dual Type Coating Thickness Tester
The LZ-990 Dual Type Coating Thickness Tester is a delicate electronic instruments. Never drop it, allow it to get
wet or leave it where it may be exposed to intense sunlight. When making measurements, use the wrist strap to
avoid accidentally dropping the unit. When not using the unit, place it in the supplied carrying case to protect it
from iron particles, etc.
• Handle the Calibration Foils with Care
The calibration foils are precisely measured for their thickness. If scratched or bent foils are used to calibrate,
accurate measurements are not possible. If the calibration foils are damaged in the process of handling, please
contact your service representatiave and purchase a replacement calibration foil specifying its thickness. In such
situations, the new calibration foil’s thickness may slightly vary from the old calibration foil’s thickness, but this
will not affect the results of the calibration.
