INTRODUCTION

This product is a portable coating thickness gauge, which can quickly, nondestructively, and accurately measure non-metallic coating thickness (such as paint, film, etc.) of the metal substrate. It Is widely used in detection areas like the manufacturing industry, Car washing industry, metal processing industry, chemical industry, and commodity inspection.

FUNCTIONS

1. The measure coating thickness of the metal substrate surface
2. Two modes: Car/User
3. Three measurement ways: single measurement, continuous measurement, and difference value measurement
4. Three calibration functions: zero calibration, two-point calibration, and basic calibration
5. Metric unit and imperial unit
6. Auto power off.

OPERATION INSTRUCTION

1. Turn on: Short press the power button to turn on the instrument. After LCD full-screen display, mode information will show on the screen (indicator Car appears under Car mode, no indicator appears under User mode), then follows the measurement interface.
2. Select mode: Long press the MODE button under the measurement interface to switch Car/User mode
3. Car mode: Car mode can be used without calibration, which can measure the coating thickness of three substrate materials-iron, aluminum and zinc, suitable for measuring the coating thickness of cars.
4. User mode: User mode requires calibration before buse, which can measure the coating thickness of substrate material for calibration.
5. Auto power off: The instrument will power off automatically in two mins of no measurement, or in five mins after measurement.

MEASUREMENT OF COATING THICKNESS

1. Press the power button in the air to turn on the instrument after LCD full-screen display follows a BI sound, which means that the measurement state begins. Every time of power on is regarded as a single measurement.
2. Press the probe lightly on the coated metal substrate, the instrument will let out two sounds of BI-BI, with LCD showing the measured value of coating thickness.
3. Press the MODE button to select the measurement way. There are three measurement ways to choose from: ingle measurement, continuous measurement, and difference value measurement.
4. Single measurement means one data each time. Continuous measurement means as long as the probe does not leave surface of the substrate, the instrument will keep measuring. Difference value measurement means the difference value between this time and last time of measurement.
5. Press the UNIT button to choose a unit. There are metric unit (mm) and imperial units (mil) to choose from.
6. If you turn on the instrument on a metal substrate, ERR (error) will show after the LCD full-screen display, then the instrument will power off because of wrong startup way.

THREE CALIBRATION WAYS UNDER USER MODE

1. Basic calibration: if the instrument is in its first use or not in use for a long time, or the substrate material to be measured is changed, substrate calibration should be taken. There are seven calibration points for basic calibration, the unit during calibration is mm.

   • Prepare 6 standard calibration films, the thickness of which is 0.05, 0.10, 0.25, 0.50, 1.00, 2 mm, and the unit is mm. At the same time, prepare the corresponding metal substrate.If you need to measure the coating or film thickness on the surface of zinc, use zinc block as substrate.The same to iron and aluminum.
     Attention: the diameter of the substrate should be longer than 50mm.iron substrate will be taken as an example to illustrate the basic calibration process in the following part:

   • Press the MODE button to maintain, then press the power button, after LCD full-screen display follows a BI sound. LCD screen shows 0.00, and the lower right part of LCD shows indicator C. which means entering into the calibration interface :

   • The probe is lightly pressed on iron substrate without coating on the surface, then the LCD shows 0.00, followed by two sounds of BI-BI, which is 0.00 calibration.

   • Remove the probe, and LCD shows 0.05mm. Now start the second calibration by putting the 0.05mm calibration film on the iron substrate and pressing the probe lightly on the iron substrate. After two sons of BI-BI, the second Calibration point is finished.

   • Remove the probe, the LCD shows the third data, do calibration in turn according to the previous method. Until the last calibration film is calibrated, LCD displays OVER, the instrument turns off after two sounds of BIBI, and the basic calibration is complete.

   • After basic calibration is completed, the coating thickness of the same material as the calibrated substrate can be measured.

2. Zero calibration: after turning on the instrument in the air, choose User mode and then gently press the probe on the surface of the substrate. Short press the ZERO button, the LCD displays 0.00, and zero calibration is completed.

3. Two-point calibration

   • First, carry out zero calibration
   • Take a calibration film (such as 1.00mm), the measured value of which is 1.05mm. Do not remove the probe, pressing the increase or decrease button calibration data, until LCD displays 1.00mm. Remove the probe and two-point calibration is completed.

OTHER ITEMS

Attention:

1. Factors that influence the accuracy of measurement and related instruction:
   • Metal thickness of substrate: Each instrument has a critical thickness for a substrate metal. If the thickness is greater than this value, the measurement will not be affected by the thickness of the substrate metal. Refer to requirementsonproduct specifications for the critical thickness of the instrument (≥0.5mm).
   • Edge effect: The instrument is sensitive to the steep change of the specimen’s surface shape. So it is unreliable to make measurements near the edge or inner corner of the object under measurement.
   • Curvature: The curvature of the object under measurement has an influence on the measurement. This influence always increases significantly as the curvature radius decreases.
   • Surface roughness: The surface roughness of substrate metal and coating has an influence on the measurement. As the degree of roughness increases, the influence increases. Rough surfaces can cause system errors and accidental errors. In each measurement, users should conduct moretimes of measurements at different places to overcome this kind of accidental error. If substrate metal is rough, users must take a few spots on uncoated substrate metal with similar surface roughness to calibrate zero point of the instrument; or dissolve and remove coating with a solvent that does not corrode the substrate metal, then calibrate the zero point.
   • Surface cleanliness: Before measurement, any attached substances such as dust, grease and corrosive substances on the surface should be removed, but do not remove any coating material.
   • The instrument cannot distinguish iron substrate from the nonferrous substrate.
   • The instrument can only measure non-metallic coating.

NOTICE FOR USERS

1. Since Car mode has built-in data, the user can no longer conduct calibration. Car mode can directly measurecoating thicknessof iron, aluminum, and zinc substrate, suitable for measuring the coating thickness of cars.
2. Under User mode, after calibrating the metal substrate, the user can only measure the coating thickness of this metal’s surface, not other metals. For example, if you calibrate an iron substrate, you cannot measure the coating thickness of the aluminum substrate.
3. User mode calibration will not influence Car mode.
4. Car mode is the default factory setting.
5. The default factory setting uses an iron substrate to calibrate the User model.
6. Calibrating under the User model, the diameter of substrate should be≥50mm, and the substrate thickness should be≥0.5mm.
