Congratulations on the purchase of our coating
thickness gauge ComBi-D3.

Description

The ComBi-D3 is a simple and cost effective
measuring device. It belongs to a range of non­destructive coating thickness gauges.

Measuring ability of ComBi-D3:

It is easy and handy to use and allows the user
to make all necessary adjustments with the aid
of a menu (MODE–button). This allows for
change to be implemented quickly and simply.
The gauge ComBi-D3 can be used for a wide
variety of applications and has to offer a large
measuring range from 0 to 3.5 mm. Modern

electronic and the robust casing guarantee an
extended lifetime for the high precision
instruments.

Battery exchange

The ComBi-D3 gauge is powered by a 9 V
alkaline battery. The battery compartment can
be found in the top back portion of the
instrument. If a battery icon appears in the
display, the battery has to be exchanged.
If a replacement battery is not available
immediately, several measurements can still be
taken until the gauge shuts down completely
(the display shows bAT and a discontinuous
beep tone is audible).

Attention: Exhausted batteries are hazardous

waste. Used batteries not with the domestic
waste decontaminate, but deliver at stated
collective places.

Switching on and off of the device

➢ The gauge can be switched on manually

via pressing of ON/OFF-button or by
directly placing the probe on the
measurement object.

➢ It appears Cd3 (name of device) and then

the last measured value.

➢ The gauge switched off automatically after

40 seconds of non-use or by long pressing
(about 3 seconds) of ON/OFF-button.

Handling and storage

The ComBi-D3 gauge is a high precision
instrument with a wide scope of applications. It
is therefore of great importance that the device
is handled with care to ensure a long life and a
prerequisite for precise and accurate
measurement results. The following guidelines
are to be followed to achieve the above:

➢ Protect the device from dust and dirt.

➢ Do not drop the device to the floor.

➢ Protect the device from moisture,

aggressive vapors and chemicals.

➢ After use please put the device in the

carrying case.

➢ Avoid direct strong sunlight and

temperature shocks as these can have a
negative influence on the measurement
result.

➢ Precise measurement results can be

achieved only with a clean probe.
Therefore, use regularly a clean, damp
cloth.

➢ Check the probe regularly for soiling such

as paint or iron particles.

➢ If the device is not used for a long time, it is

advisable to remove the battery to avoid
possible damage caused by the leakage of
a battery.

➢ If the device has a failure, contact your

supplier for help.

Taking measurements

➢ Hold the device vertically on the location to

be measured.

➢ Place the probe flat (avoid tipping!).

➢ To get the best results, place the thumb on

the elliptical indicated position with the
other fingers behind the gauge for balance.

➢ A beep is audible and the measured value

appears on the display.

➢ Improper placement, as well as picking up

the device before the end of the
measurement and the zeroing on a non­metallic surface (substrate) is displayed
with Er0 (error).

➢ If the coating thickness exceeds the

maximum range (3500 µm) or if the device
is placed on the incorrect substrate (wood,
paper, cardboard etc), the display shows InF
(infinite).

➢ The V-groove on the measuring head helps

by measurements on round objects, such
as rods, tubes, shafts, radii etc.

Please do not perform measurements on
magnets and in magnetic fields.

Magnetic f ields influence the results by the
Fe- and strong electromagnetic radiation
has the influence by the NFe
measurements.

Zero calibration

A zeroing of the instrument is necessary after
switching on, by different measurement
processes, inserting of new battery or after
prolonged use.

Place the device on the iron- or the aluminum
plate in the carrying case. You can also use a
piece of uncoated ferro ( Fe) or non- ferro (NFe)
metal (substrate) used in your process. If the
displayed value is out of the basic tolerance,
the instrument has to be zeroed. The following
steps are to be taken to zero the gauge:

➢ Remove the device from the zero plate or

the substrate.

➢ Press the Zero button. The display shows

P0.0 (zero point).

➢ Place the gauge on the zero plate or the

substrate. PIn (infinity) appears followed by
a beep tone.

➢ Lift the device at least 5 cm from the zero

plate. 0.0 appears followed by another
beep.

➢ To check the zeroing place the gauge on

the zero plate or the substrate again. 0.0
should appear on the display followed by
beep. If the result is different repeat the
zeroing procedure.

➢ The device is now ready for accurate

measurements.

Note that it is not necessarily to receive the
same displayed result by repeated
measurements at the same location.
Measurement variations can be caused by
roughness, dirt or bumps.

The menu of Com Bi -D3

The various options from the menu can be
accessed by repeatedly pressing the Mode­button. Pressing the Enter-key allows to select
the displayed option. Now the Mode-button
change or select the setting. Pressing of Enter
confirms your choice and exits the menu.

rST - Resetting the average value (mean)

of the measurements
(YES - Yes, no - no)

GAG - Choice of substrate material

AUT - automatic detection

(recommended) indicated by AUTO
icon in the display

FE - only steel or iron
nFE - non magnetic metals

(aluminum, copper etc.)

CnT - continuous measurement indicated

by CONT icon in the display
(On - On, OFF - Off)

UnT - Choice of measuring unit between

microns / mm and mil
(25.4 - µm/mm, 1.00 - mil)

bEP - Switching on or off of tons keys

(On - On, OFF - Off)

Sn - Displays the serial number of the

device

iron

NFe:
all isolating

coatings such as
lacquers,
synthetics,
enamels, paper,
glass, rubber etc.

on copper,

aluminum or brass.
This includes
anodized coatings
on aluminum as
well.

Automatic detection for the measurement
on ferro or non-ferro

The automatic detection of subsurface
material (Fe - ferro or NFe - non-ferro) is
indicated by the AUTO icon in the display.
Before each measurement, the device
checks the material and selects the
corresponds measurement method.
If the device is placed on magnetic material
(ferro), Fe icon is indicated in the display. By
measurements on non magnetic metals (non
ferro), nFe icon is indicated in the display.
The GAG option of the menu enables or
disables the automatic detection.

Display of the average value (mean) and the
number of measurements

The device calculates with each measurement
and without storing of individual results the
average value. The display of mean is due to
the short press (less than 3 seconds) of the
ON/OFF-button and is indicated with Ave
(average) icon in the display. If the ON/OFF­button is short pressed again, the number of
last measurements applied to the mean
together with n icon appears in the display. The
rST option of the menu resets these values.
