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 used. You can select
the type of probe via MENU system, or it will be work
automatically.
The gauges conform to the following industrial
standards:
GB/T 4956-1985
GB/T 4957/1985
JB/T 8393-1996
JJG 889-95
JJG 818-93

1-1 Application
This compact and handy gauge is designed for non-
destructive, fast and precise coating thickness
measurement. 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.
MCT-822 gauges are 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 work
on the magnetic induction principle, for measurement
on non-ferrous metal substrates, it works on the eddy
current principle.
Measurement values and user information are shown
on LCD, A display backlight ensures easy reading of
screen data in dark conditions.
Two different operating modes are available: DIRECT
mode and GROUP mode.
DIRECT mode is recommended for simple, quick,
occasional measurements. It provides statistical
analysis. Single values are not saved. The statistical
analysis program can evaluate 80 readings.
GROUP mode permits measurement and storage of
readings in a free programmable memory. A maximum
of 400 readings and 4 series of measurements can be
analyzed according to various statistical criteria.
1-3 Supply Schedule
Gauge with two 1.5V battery, plastics carrying case,
operating instructions (English), steel and aluminum
substrate.
USB connecting cable
Program disc for windows 98/2000/xp/Vista/7
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 by the spring mounted sleeve and put on
measuring object.

2. Preparing
2-1 Power Supply
For checking the battery’s state of charge please press
key:
No LC display: Battery missing or battery charge too low
to illuminate display.
Display: gauge switches off after about one second:
Replace battery immediately.
Note that the gauge will make faulty measurements if
the voltage is very low.
2-2 Replacing The Battery
Place the gauge upside down on a suitable surface.
Remove the screws from the battery compartment with
a cross tip screwdriver.
Raise the lid of the compartment.
Remove the battery.
Close the lid and fasten with screw.
Caution: make sure the anode and cathode are
correctly positioned.
2-3-1 Menu System
Press to power on; the gauge will work in
measuring mode. Press red-bar button into MENU
mode. See following MENU system arranges:
NOTE: MENU system arranges need to be known well
for your works.
