When the UV LED function is turned on, it will radiate intense UV light
during operation. Since UV light can be harmful to eyes, do NOT look
directly into the UV light, even through an optical instrument. In case of
the light reection, UV protective glasses are required to use in order to
avoid damage by the light.
CAUTION
* Do not use the unit near any device which
generates strong electromagnetic radiation or
near a static electrical charge, as these may
cause errors.
* Do not use the unit where it may be exposed
to corrosive or explosive gases. The unit may be
damaged, or explosion may occur.
* Do not keep or use this unit in an environment
where it will be directly illuminated by sunshine,
or where it condensation. If you do, it may be deformed, its insulation may
be damaged, or it may no longer function according to specication.
* Do not place the meter on or around hot objects (70°C/158°F). It may
cause damage to the case.
* If the meter is exposed to signicant changes in ambient temperature,
allow 30 minutes for temperature stabilization, before taking measurement.
DANGER
INTRODUCTION
This instrument is a 4 digit, portable, easy to use and compact-sized digital
“ferrous” or “non-ferrous” coating designed for simply one hand
operation. Meter comes with backlight LCD display and Auto Power O (60
seconds approx.) to extend battery life.
SAFETY INFORMATION
It is recommended that you read the safety and operation instructions
before using the coating thickness gauge.

* Condensation may form on the sensor when
going from a cold to hot environment. Wait for 10
minutes for condensation to dissipate before
taking measurements.
*This unit is not constructed to be waterproof and
dustproof. Do not use it in a wet or very dusty
environment.
*In order to take accurate measurement, make
sure the sensing tip contacts the coated surface
tightly without tilting.
* Please make sure there is no air bubbles between
substrate and coating.
*Substrate Zeroing Calibration: Must be implemented for each
use.
*Two point calibration:Must implement for frequent testing points to
increase measuring accuracy.
*The enclosed zeroing plates are only suitable for the use of calibration of
coating thickness meter itself. Apart from that, the meter should be
performed two point calibrationmethods to get accurate readings before
use.
The zeroing on specic material substrate still needs to be done before
taking formal measurements, such as Iron, Steel, Bronze, Copper, Nickel,
Zinc, and SUS304 and so on, which is to avoid the measuring errors that
cause by the dierence of individual substrates.The end users can get
much more accurate measuring readings on the specic metal under test
by doing two calibration methods.
WARNING
ELECTROMAGNETIC FIELD INTERFERENCE
This instrument uses magnetic eld method to measure the coating
thickness on ferrous metal base. If this meter was placed in the
environment with 20mG (mini Gauss) or above, the accuracy would be
aected. Suggest that the meter should to put far away from the interfered
source at least 30cm.
