2.2 WORKING CHARACTERISTICS
The NexPTG device has been specially designed for measuring the thickness of lacquer coat layers
on car bodywork. It is intended for testing steel, galvanized steel and aluminum surfaces. It has the function of
automatic identification of the tested substrate. The device performs a lacquer coating analysis and transmits
data wirelessly to a dedicated mobile application (installed on an external device), where it is interpreted.
Allows examination and comparison of individual car bodywork for the thickness of the lacquer coat.
Detects possible interference with the coating in the wider automotive industry (auto detailing / sheet
metal works / lacquering / mechanical).
Dedicated to appraisers / claims adjusters / employees of the insurance industry for private use

2.4 CONSTRUCTION OF THE DEVICE
The gauge consists of two panels: the front panel (with diodes indicating power supply and connection, and a
multifunction key –switch on, switch off, save measurement) and the rear panel with the battery cover. The
electronics assembly is terminated with a probe with a measuring sensor.
3. OPERATION OF THE NexPTG GAUGE
Turn the device on or off by pressing the button and holding it down for 3 seconds, until the red diode on
the front panel lights up. Pressing this button once briefly saves the measurement in the application.
The NexPTG application can be downloaded from: Google Play and App Store.
3.1 FIRST START-UP
In order to start the NexPTG gauge the button 3 should be
held down for three seconds until the power diode lights up on
the panel 2 Next, start the NexPTG application on the mobile
device (external). Correct communication will be signaled by the
lighting up of the blue diode 1 .
WARNING: The first start of the gauge requires access to the
Internet.
If there is no communication, the device (telephone, tablet,
smartphone) should be restarted and the NexPTG mobile
application should be restarted.

3.2 CALIBRATION OF THE GAUGE
The gauge is calibrated at the factory. Calibration is performed after prolonged non-use of the gauge. Both
devices should communicate with each other via a wireless connection. Correct communication is signaled by
switching on the blue diode. We carry out calibration after starting the NexPTG gauge and application. The red
diode indicates that that the device is properly turned on.
Spread the calibration plates from the kit on a hard, stable and flat surface with color upwards (steel - blue and
aluminum - white, each 90μm). When calibrating the gauge, the plates should lie on a non-metallic surface, so
as not to disturb the calibration process and should be clean. Do not hold the plates in your hands during
calibration. The gauge should be pressed against the plates so that the probe adheres firmly with its entire
surface. The device must not stand on them loosely.
In the main menu of the NexPTG application, find the calibration icon and clicking on it follow the
messages that appear. The calibration process consists of two steps:
1. To calibrate, apply the gauge to the supplied steel plate, colored blue.
NOTE: the gauge should be placed in the center of the calibration plate
2. Next, apply the gauge to the supplied aluminum plate, colored white.
NOTE: the gauge should be placed in the center of the calibration plate.
Its correct implementation should end with a text message with the text "Calibration completed successfully". A
correctly calibrated gauge should indicate 90 μm plates (accuracy according to the table).
If this is not the case, start the device and application again or contact the distributor.
3.3 PERFORMING MEASUREMENTS
FOR NEXPTG STANDARD AND NEXPTG ADVANCED METERS
Before starting measurement, make sure that:
all radios are switched off (radio, CB radio). If there is a CB antenna on the vehicle –remove it from the
car for the duration of the measurement;
there are no devices nearby that generate strong electromagnetic radiation and there is no close
presence of static electric charges, as they may cause erroneous measurements;
no measurement is made in conditions such as: significant presence of dust, sediments, air bubbles,
high moisture, high humidity, rain, snow;
the tested surface is clean.
The device is designed to test magnetic metal (steel, galvanized steel) and non-magnetic (aluminum) surfaces of
car bodywork. The types of surface tested are detected automatically. Attention should be paid to the correct
use of the device so that the probe does not slip or move from the test surface. It should be applied so that it
adheres firmly to the bodywork of the tested vehicle with all its diameter (20 mm) (see below).

Then wait for the measured value to appear on the screen of the external device.
FOR NEXPTG PROFESSIONAL METER
Before starting measurement, make sure that:
all radios are switched off (radio, CB radio). If there is a CB antenna on the vehicle –remove it from the
car for the duration of the measurement;
there are no devices nearby that generate strong electromagnetic radiation and there is no close
presence of static electric charges, as they may cause erroneous measurements;
no measurement is made in conditions such as: presence of dust, sediments, air bubbles, high moisture,
high humidity, rain, snow;
the tested surface is not dirty.
The device is designed to test magnetic metal (steel, galvanized steel) and non-magnetic (aluminum) surfaces
of car bodywork. The types of surface tested are detected automatically. Attention should be paid to the
correct use of the device (see below).
Then wait for the measured value to appear on the screen of the external device.

3.4 OPERATION OF THE NexPTG APPLICATION
The application has been designed and written specifically for the NexPTG gauge and is an inseparable part of it
that allows the proper functioning of the device. The measurements are displayed in the main application view
and the MEASUREMENT tab.
SETTINGS measurement mode unit of measure other functions
The full NexPTG application manual is available on the manufacturer's website at www.nexdiag.com and in the
main application menu in the HELP tab. All copyrights and licenses relating to the NexPTG application are the
property of the manufacturer. It is prohibited to use the application in any other way than the author has
assumed.
4. MAINTENANCE
It is recommended to periodically clean the device with a cloth. Remember to keep the probe clean.
Its soiling can cause differences in measurements.
4.1 BATTERY REPLACEMENT
To replace the battery, unscrew the screw that secures the battery cover to the housing,
raise it as shown in the picture below. Then replace the batteries with new ones and screw
on the cover.
The gauge is powered with 1.5 V LR6 (AA) alkaline batteries –2 pcs. The low battery indicator displayed on the
screen of the mobile device (external) indicates the need to replace the batteries with new ones. Their
discharge status is displayed as a percentage in the lower left corner of the main menu of the NexPTG
application.
IMPORTANT!
Pay attention to the polarity of the battery.
Incorrect operation of the gauge may be caused by battery depletion.
Alkaline batteries should be used.
