1. General Information

The coating thickness gauges work either on the magnetic induction

principle or on the eddy current principle, depending on the type

of probe used. You can select the type of probe via MENU system,

or it will work automatically.

Features

• Measured Coatings: Non-magnetic coatings (e.g. paint, zinc)on steel;

Insulating coatings(e.g. paint, anodizing coatings)on no-ferrous metals•

• Operating with MENU easily

• Memory for 2500 readings

• Delete single readings and all group readings easily

• Error indication

• Data transferred to PC via Bluetooth for analysis

• Disable Auto-Power-off function via MENU setting

Coating Thickness Tester User Manual

1-1. Application

• This compact and handy gauge is designed for non-destructive, fast

and precise coating thickness measurements. The principal applications

lie in the field of corrosion protection. It is ideal for manufacturers

and their customers, for offices and specialist advisers, for paint shops

and electroplaters, for the chemical, automobile, shipbuilding and

aircraft industries and for light and heavy engineering.

• The coating thickness gauge is suitable for laboratory, workshop

and outdoor use.

• The probe can work on both principles, magnetic induction and on

the eddy current principle. One probe only is required for coating

measurement both on ferrous and non-ferrous metal substrates.It is

adaptable to specific tasks: i.e. they can be used on special geometries

or on materials with special properties.

1-2. Description of the Gauge

• For measurement on steel substrates, the gauge works on the magnetic

induction principle, for measurement on non-ferrous metal substrates,

it works on the eddy current principle.

• Measured values and user information are shown on LCD. The display

with backlight ensures easy reading of screen data in dark conditions.

1-3. Supply Schedule

Gauge with two AAA 1.5V batteries, plastics carrying case, operating

instructions (English), steel and aluminum substrate, and standard flake

for calibration.

1-4. Probe

The Probe systems are spring-mounted in the probe sleeve. This

ensures safe and stable positioning of the probe and constant contact

pressure.

A V-groove in the sleeve of the probes facilitates reliable readings

on small cylindrical parts. The hemispherical tip of the probe is made

of hard and durable material. Hold the probe by the spring mounted

sleeve and put on measuring object.

2. Ready to start

2-1. Power Supply

For power on, please press and hold button. If no LCD display:

please check if the battery is correctly installed or it is in low battery.

Display: Please replace battery immediately.

Note that the gauge will make faulty measurements if the voltage

is very low.

Note: When power on, please away from any metal at least 10 cm

above

Before each measurement, zero calibration is recommended.

2-2. Replacing the Battery

• Power off the meter.

• Open the battery cover.

• Remove battery.

• Insert new battery.

• Close the battery cover.

Caution: Make sure the anode and cathode are correctly positioned.
