1. Technical specifications
Basic specifications of the device:
- measurement on steel, galvanized steel, aluminium sheets and other by defining
a reference point;
- measurement based on a defined reference point;
- measurement resolution: 1 or 10µm;
- measurement range: from 0µm to 2100µm;
- measurement memory (also after turning the device off): 100 units;
- zeroing function;
- LCD backlight;
- automatic shut-off after longer idleness;
- powered by 9V alkaline battery (e.g. 6LR61) or corresponding accu.
2. Getting started
Coating thickness gauge GL-6+ is designed to measure the thickness of a steel, galvanized steel or
aluminium sheet paint coating. It is also possible to make a measurement based on a defined reference point..
The device has a LCD backlight which makes measuring in places with insufficient 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 flap and place correctly the battery or
accu by connecting it to the clips on the cable.
WARNING! The device is preset to galvanized steel and aluminium (Zn/Al)! Should the measurement be
taken on older cars with non-galvanized steel bodywork, the „Steel” option shall be chosen.
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 more against the green side of the calibration
sheet, wait until the result stabilizes and press the “OK” button while the sensor still touches the sheet. On the
display will appear a „OK...” 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) button.
WARNING! While zeroing, the calibration sheet should be placed on a flat, stable non-metalic surface (e.g.
do not place the sheet on the bodywork). Also, please avoid holding the sheet in Your hands as this may affect
the operation.
Please note that zeroing is worth to be made when the measurement conditions are changing (e.g. the
temperature or humidity rises or falls).
ATTENTION!
1. Use only alkaline batteries as normal batteries provide unsufficient power.
2. Instead of a alkaline battery You can use a compatible, fully charged accu.
3. If the device seems to work improperly it can be caused by an empty battery or accu.
To take a measurement please put the device’s sensor against the examined surface. The sensor should
adhere as flat 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.
3. Gauge manual
The device is operated with 2 buttons:
- (OK / MENU): turns the device on, accepts the selected functions and returns to the main menu, when
pressed during the measurement it memorizes the displayed value;
- (FUNCTION): switches between the functions in the main menu, switches between the stored
measurement values.
To turn the gauge on please press the (OK) button for about 1 second. After displaying the company’s logo and
the device’s type, the device switches automatically to the main menu. In the first line You will see a
„>MEASUR” caption and in the second „SUBST” and the battery monitor. The „>” symbol indicates the
currently selected function. Please press the (FUNCTION) button to switch between the following functions:
-MEASUR –measure function: takes measurements;
-SUBST –substance function: allows to choose the measured material;
-MEMORY –memory function: recalls the stored measurement values;
-REF PT –reference point function: sets the reference point;
-OFF –off function: switches the device off;
-DELETE –delete function: deletes the stores measurement values;
-ZERO –zeroing function: calibrates the gauge;
-ASSIST - Enables / disables the measuring assistant.
To select a function please press the (OK) button.
Measure function
After You select this function the display will show the currently selected material, e.g. “Zn/Al” and the
battery indicator in the first line and „----um” in the second. The gauge is ready to take measurement.
After You put the sensor against the bodywork the result of the measurement will be shown on the display in the
second line.
To store the result please press the (OK) button when taking the measurement. A „*” symbol appears next to the
shown value. Attention! The capacity of the device’s memory is 100 results. After that the latest stored values
are deleting the oldest ones.

After You finish taking the measurements please return to the main menu by pressing the (OK) button.
Memory function
This function allows You to recall the latest measurement values. Please press the (FUNCTION) button to
switch between the stored results. The first displayed result is the oldest one. After You get to the last result the
device returns automatically to the first one. To return to the main menu please press the (OK) button.
Substance function
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 (FUNCTION) button, to accept the selection press the
(OK) button.
Reference point function
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 first line and in the
second „-------”. In that moment please put the sensor against the sample sheet, wait until the result stabilizes and
press the (OK) 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.
Off function
Accept this function with the (OK) button to turn the gauge off.
Delete function
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
Use this function before You start to take measurements. After choosing this function 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 well
calibrated. Should the aberration be larger than 0 +/-10µm, please put the sensor once more against the green
side of the calibration sheet, wait until the result stabilizes and press the (OK) button while the sensor still
touches the sheet. On the display will appear a „OK...” 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) button.
WARNING! While zeroing, the calibration sheet should be placed on a flat, stable non-metalic surface (e.g.
do not place the sheet on the bodywork). Also, please avoid holding the sheet in Your hands as this may affect
the operation.
Please note that zeroing is worth to be made when the measurement conditions are changing (e.g. the
temperature or humidity rises or falls).

Assistant function
The function enables to interpret correctly if the measured body-work has ever been repaired.
While the measurement is taken and the ‘assistant’ function is on, following phrases may appear:
-LAC.OK –LED is off
-2xLAC! –LED flashes
-PUTTY! - LED light continuously
For technical reasons the mentioned phrases are abbreviations. The producer reserves the right to reduce or increase the number of
compartments in the process of modernization of the device.
The assistant function is to be helpful in the measurements interpretation. It cannot be the only hint to decide if
the body-work has or has not been repaired. However many people who use the device claim that it is helpful in
interpreting the results.
