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.
Notice: In order to obey the shipping security rules and passing the customs security check. We had put a insulation strip under the battery to make it insulated. You need to take the strip off and re-install the battery for the first-use.
Specification
Type: Painting Thickness Tester Measuring Range: 0.00mm - 2.20mm, or 0.0mil - 86.0mil Measurement Accuracy: For measurements in “NFe” or “Fe” test mode in which the tester has been properly calibrated: ± 0.05mm For measurements in auto test mode and on object with aluminum substrate: ± ( 2% of reading + 0.05mm ) For measurements in auto test mode and on object with steel substrate: ± ( 10% of reading + 0.10mm ) Note:The above accuracy specifications assume that the operating temperature is 23º C ± 5º C and the operating relative humidity is ≤ 75%. Resolution: 0.01mm/0.1mil Power Supply: 3V button cell, CR2032 or equivalent, 1 piece Operating Environment: 0°C~40°C, Relative humidity Temperature Coefficient: 0.15x(2% of reading ± 0.05mm)/°C(28°C) Storage Environment: Temperature: -10ºC to 50ºC Relative Humidity: ≤ 80% Size: 6.9*3.8*2cm Weight: About 29g(including button cell)
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. The display shows all segments and symbols momentarily. Then it shows the " AUTO " symbol and the measurement unit “ mm ”, and meanwhile, " ", " ", and " " appear on the display sequentially and repeatedly. 2. Press the " " button to select desired measurement unit - mm or mil. 3. After you turn on the tester, it will default to auto test mode and the display will show " AUTO " as an indication. You can repeatedly hold down the " " button for about 1 sec to step through " NFe " test mode ( " NFe " appears as an indication ), " Fe " test mode ( " Fe " appears as an indication), and back to the auto test mode ( " AUTO " appears as an indication ). I f you can not obtain the naked substrate of the object to be measured and have not calibrated the tester using the naked substrate of this object, you must select auto test mode. The advantage of using auto test mode is that it is not necessary to calibrate the tester, and the disadvantage is that measurement accuracy in auto test mode is relatively low.
If you have calibrated the tester using the naked substrate of this object in the " NFe " or " Fe " test mode, set the tester in the same test mode ( in which the tester has been calibrated by using the naked substrate of this object ). The advantage of using " NFe " or " Fe " test modes is that measurement accuracy in " NFe " or " Fe " test mode is high, and the disadvantage is that the tester must be calibrated in this selected test mode beforehand by using the naked substrate of this object.
4. Firmly press the tester's probe perpendicularly against the surface of the object to be tested. When the tester detects a stable reading, this reading will be shown on the display and it is the value of the total thickness of the non-magnetic coatings on the substrate. This reading will be held on the display until the tester turns off or you make a new measurement. If necessary, you can press the “ TEST ” button to erase this reading and then test again.
5. If you have not operated the tester about 30 secs, it will turn off automatically. To turn off the tester manually, hold down the " TEST " button for more than 1 sec.
HOW TO CALIBRATE THE TESTER
Before you make measurement in " NFe "or " Fe " mode, you must make sure that in this mode the tester has been calibrated by using the naked substrate of the object to be tested or using a naked substrate which is completely same as the substrate of the object to be tested.
After you finish calibrating the tester in " NFe " or " Fe " test mode, the tester will save the resulting calibration data in this test mode automatically. The calibration data will not be lost even when the tester turns off or when you replace the button cell. But whenever you calibrate the tester again in the same test mode, the already existing calibration data saved in this test mode will be overwritten by the new calibration data. Thus, only the lastest calibration data of all calibration data obtained in " NFe " mode can be retained in " NFe " mode, and only the lastest calibration data of all calibration data obtained in " Fe " mode can be retained in " Fe " mode.
