Safety Information
CAUTION
•
Do not use the unit near devices that generate 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 an explosion may occur.
•
Do not keep or use this unit in direct sunlight or where condensation is present. The meter’s housing
could become deformed, its insulation may be damaged, or it may no longer function according to
specification.
•
Do not place the meter on or around hot objects (70°C/158°F); otherwise damage to the case is likely.
•
If the meter is exposed to significant changes in ambient temperature, allow 30 minutes for
temperature stabilization, before taking measurements.
•
Condensation may form on the sensor when moving from a cold to a 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 extremely dusty
environment.
•
In order to take accurate measurements, ensure that the sensing tip contacts the coated surface tightly
without a tilt angle.
•
Please ensure that there are no air bubbles between substrate and coating.
•
Substrate zero calibration must be performed before each use.
The enclosed zeroing plates are suitable
for the zeroing calibration as described in this User Guide.
•
To ensure measurement accuracy, the Two-point Calibration, as described in this User Guide, is
recommended before each use.
•
Zeroing on a specific material substrate still needs to be done before taking formal measurements, such
as for Iron, Steel, Bronze, Copper, Nickel, Zinc, SUS304, etc. This is to avoid measurement errors caused
by the differences in individual substrates. End users can expect the best results on a specific metal by
performing a Zero calibration and a Two-point calibration as described in this User Guide.
WARNING
This instrument uses a magnetic field method to measure the coating thickness on a ferrous
metal base. If this meter is placed in an environment of 20mG (milli Gauss) or above, its
accuracy will be affected. The meter should be kept at least 30cm away from the source of
interference. The list below can be used as a reference for interference potentials.
Electromagnetic field strength is shown in milli Gauss:
Electromagnetic Source: 0cm 30cm
Cellular Phone Charger: 50~ 500 < 1
Notebook Power Supply: 100~ 1000 < 5
LCD Display:
10~ 100 < 1
Fan:
100~ 1000 < 5
Reading Lamp:
400~ 4000 < 10
Note: Any device with an internal coil should be considered as a possible interference
source.
