Item Description:
This tester is designed to not-destructively measure the thickness of non-magnetic coatings(including paint, enamel, plastic, epoxy, etc)on iron, steel or aluminum.
EM2271 Specifications:
• Measurement range: 0.0 to 2.0 mm, 0 mil to 80 mil
• Accuracy: 2%rdg +-0.1 mm, or 2%rdg+-4 mil
• Resolution:0.1 mm/1 mil
• Measuring technology: Magnetic
• Size :6.9 x 3.8 x 2 cm
• Weight: About 23 grams (including button cell)
How the device work:
1. Probe
Before measurement, place the tester with its probe firmly against target surface.
2. Display
3. “TEST” button
（1）. Press “TEST” button to turn on the tester. Press and hold down this button for about 1 second to turn off the tester.
（2）. Press “TEST” button to delete the reading on the display, the display will show “- -“.
4. “UNIT” button
Press this “UNIT” button to select desired unit: mm or mil
EM2271A Specifications:
The upgraded EM2271.
It can measure the Fe & NFe.
Accuracy improved 10, measurement range extended,
resolution higher, better cost-efficiency.
For measurements in AUTO test mode and on object with steel substrate
±(10% of reading + 0.10mm),
most car is made of steel, and, if you get result of 0.00mm or 0.01mm , it is under normal
condition, acceptable error, because most car paint thickness is 0.1-0.15mm.
Operating Instruction:
1. Hold the tester and make sure that it is as least 20cm away from the object to be tested and other objects. Then press the “TEST” button to turn on the tester.”–“appear on the display and flashed, meanwhile the unit “mm” appear.
2. Press the “UNIT” button to select desired unit – mm or mil.
3. Place the tester’s probe perpendicularly on the surface to be tested, the display will show the coating thickness.
*If the display shows”–“,it means that the tester does not detect any iron, steel or aluminum substrate.
*If the display shows”OL”,it means that the coating thickness exceeds the tester’s measuring range.
*If the display shows”- 0″,it means that the probe has wear or the substrate under the coatings may be other kind of metal other than iron, steel or aluminum.
4. When you make measurement, the reading will remain on the display if you move quickly the tester away from the surface under test; and you can press the “TEST” button to delete this reading, the display will show “–”
5. If you do not press any button and the tester does not detect the presence of steel, iron or aluminum for about 30 seconds, the tester will turn off automatically. If you want to turn off the tester manually, press and hold down the “TEST” button for more than about 1 second.
