How Does A Paint Thickness Meter Work?

1. Power on/off of the Paint Thickness Gauge

Push the power button until the power is turned on.

NOTE: If there are magnetic metals near the magnetic probe at the moment of the switch on, the magnetic pull-off gauge will display an alarm “Surround Error!". Under this circumstance, you should take the gauge far from magnetic metals and wait few seconds it can go normal.

When the gauge is switched on, press the power button a while to turn the power off.

NOTE: Mikrometry's magnetic coating thickness gauge can power off automatically if no operation for 3 minutes. Before turning it off, it will sound for a few beep prompt. If you do not want to power off, simply press any key that can abort.

2. Measuring Procedure of Paint Thickness Gauge

2.1 Parameters selection

First, confirm measuring parameters and instrument used to measure paint thickness should suitable for your requirements.

2.1.1 Measurement Mode

There are two modes: Single Mode and Continuous Mode. It's displayed in the upper left corner of the LCD display.

It is usually to choose Single Mode, that is, when a measurement is completed, you should lift the probe and then the next point measurements. In this mode, the measurement data can be stored automatically, and calculated mean value.

Select "Continuous Mode", and you can slide the probe on the measuring surface for measurement continuously. However, this mode will not perform data storage and statistical processing.

2.1.2 Measurement Units

The instrument has two kinds of units available for selection: μm (microns) and mils (micro inch).

2.2 Accuracy verification

2.2.1 Using a calibration substrate and Standard thickness foil to verify the instrument. Generally if the measurement.

error is not out of the accuracy of specifications it can be used normally.

Methods: Select a Single-Mode and μm, press the probe on the surface of the substrate, and push for zeroing. Place a foil on the substrate to measure. Comparing the measured value and the standard value of the foil to obtain the measurement error.

2.2.2 If the error is large, calibration is needed.

2.3 Test piece ready

2.3.1 Test-piece should be ferromagnetic base material coated with a non-magnetic coating;

2.3.2 The measuring surface should be regular, and smooth;

2.3.3 The thickness of the test piece is not less than 2mm;

2.3.4 The measuring surface should be clean and free of grease.

2.4 Measurement

Press the probe perpendicular to the surface of the test piece.

When the thickness values is obtained, a sound is uttered. In Single Mode, then you can lift the instrument to read or do the next measurement. In Continuous Mode, then you can move the probe to the next measurement position. This is almost the whole process of how does a paint meter work.

NOTE: In Single Mode, you need to lift the instrument away from the test surface 10cm or more, and the time interval between two measurements should be no less than 1 second.

Using Continuous Mode often, may cause the probe wear and galling test surface is easy. We, therefore, recommend to use Single Mode for normal measurements, if not


2.5 Data read and browse

2.5.1 Read measuring value

Read the measured value from the LCD

The maximum point for the statistical set is 9. It will start the next statistics set automatically if more than 9 points. Enter the menu or push will renew statistical set and average.

2.5.2 Data Browse

In Single Mode, each measuring value is stored automatically In the

measurement mode, you can press the "arrow-down" button to browse them.

Data Browse of Magnetic Coating Thickness Gauge

NOTE: The magnetic film thickness gauge can store up to 500 of the measurement value. The greatest number is the most recent measurement. After the data store reaches 500, the following data will be stored and pile out the first data automatically. Therefore, record the user data as soon as possible for not to lose it.

2.6  Passing measurement

2.6.1 In the Single Mode, you can also be set upper and lower limits for passing judgment and screening tests.

2.6.2 When the measured value exceeds the tolerance, it will

sound indication.

2.6.3  To set upper and lower limits
