Getting started2.
Coating thickness gauge TW-6 is designed to measure the thickness of a steel, galvanized
steel or aluminium sheet paint coating. The measurement resolution equals 10µm. The device is
equipped with an internal EEPROM memory for 100 measurements which enables to check the
results after the measurement is made. The memory doesn’t get deleted after turning off the
device, although it is possible to delete it from the menu. The device has a LCD backlight which
makes measuring in places with insufcient light (e.g. garage) much easier.
Before You start to use the device, please place a new alkaline battery or a fully charged accu in
the back side of the device’s housing. In order to do it please take off the battery ap and place
correctly the battery or accu by connecting it to the clips on the cable.

Zeroing (calibration)
Before You start to take measurements, please check whether the gauge is calibrated. To do it
properly, please select the Zero function from the main menu and put the sensor against the
green side of the calibration sheet. If the display shows a 0 +/-10µm value, it means that the
gauge is calibrated. Should the aberration be larger than 0 +/-10µm, please put the sensor once

OK [MENU] button while the sensor still touches the sheet. On the display will appear a O K ...
caption and the device will return automatically to the main menu.
If the device is calibrated, You can cancel the Zero function by pressing the OK [MENU]
button. Please note not to press the OK [MENU] button before the ------ caption appears in
the second line of the display – otherwise the gauge will decalibrate!

To take a measurement please put the device’s sensor against the examined surface. The sensor
should adhere as at as possible. The examined surface should be clean and smooth, otherwise
the measurement may be incorrect. It is advised to hold the gauge with both hands and press
gently towards the examined surface to eliminate vibration. Usually it takes 1-2 seconds to
stabilize the measurement result.
Gauge manual3.
The device is operated with 2 buttons:
button • OK [MENU]: turns the device on, accepts the selected functions and returns
from them to the main menu, when pressed during the measurement it memorizes the
displayed value;
button • FUNCTION: switches between the functions in the main menu, switches between
the stored measurement values.
To turn the device on please press the OK[MENU] button for about 1 second. After displaying
the company’s logo and the device’s type, the device switches automatically to the main menu.
You will see on the display Measur in the rst line and Memory in the second line. The *
symbol indicates the currently selected function.

After You nish taking the measurements please return to the main menu with pressing the
OK[MENU] button.
Memory function - Memory
This function allows You to recall the latest

displayed result is the oldest one. After You get to the
last result the device returns automatically to the rst
one. To return to the main menu please press the OK
[MENU] button.
Off function - Off
After You accept this function with the OK[MENU] button the device turns off.
Substance function - Subst
The substance function allows You to choose the material which will be measured. You have the
following possible choices:
galvanized steel / aluminium (• Zn/Al);
steel (• Fe);
reference point (• Ref)
You can switch between the sheet materials with the FUNKTION button, to accept the selection
press the OK [MENU] button.
Reference point function - Ref
To take the measurement in reference to a sample You can
use the reference point function. You can easily compare the
further results with a sample one.
After choosing this function on the display will appear a Set
Ref caption in the rst line and in the second -------. In that
moment please put the sensor against the sample sheet,
wait until the result stabilizes and press the red button to set
the reference point.
Then, to take the measurement according to the reference
point, You have to choose the „reference point” option in the substance function menu. During
the measurement a Ref caption will appear on the display. If the result is negative, the thickness

of the coating is thinner than the sample. If positive, it’s thicker.
You can use this function to measure the coating thickness on Your own material sample. In
order to do this You have to set the reference point on a clear sample sheet, the same which will
be measured afterwards.
Delete function - Delete
Choose this function to delete all measurement values stored in the device’s EEPROM internal
memory. After deleting the stored results the device returns to
the main menu automatically.
Zeroing function - Zero
Use this function before You start to take measurements. After
choosing this function put the sensor against of the calibration
sheet. If the display shows a 0 +/-10µm value, it means that the
gauge is well calibrated. Should the aberration be larger than
0 +/-10µm, please put the sensor once more against of the
calibration sheet, wait until the result stabilizes and press the
OK[MENU] button while the sensor still touches the sheet.
On the display will appear a O K ... caption and the device will
return automatically to the main menu.
If the device is calibrated, You can cancel the Zero function
