What do F, N and FN stand for in coating thickness gauges?
The coating thickness gauge can non-destructively measure the thickness of non-magnetic coatings (such as aluminum, chromium, copper, enamel, rubber, paint, etc.) and non-magnetic coatings on magnetic metal substrates (such as steel, iron, alloys and hard magnetic steel, etc.) The thickness of the non-conductive coating (such as enamel, rubber, paint, plastic, etc.) on the metal substrate (such as copper, aluminum, zinc, tin, etc.). So what do F, N and FN stand for in coating thickness gauges? Shenzhen Yuanhengtong Technology Co., Ltd. will introduce to you in detail:
F stands for ferrous ferromagnetic substrate. The F-type coating thickness gauge uses the principle of electromagnetic induction to measure non-ferromagnetic coatings and coatings on ferromagnetic metal substrates such as steel and iron, such as paint, powder, plastic, and rubber. , synthetic materials, phosphate layer, chromium, zinc, lead, aluminum, tin, cadmium, porcelain, enamel, oxide layer, etc.
N stands for Non-ferrous non-ferrous substrate. The N-type coating thickness gauge adopts the eddy current principle; it is used to measure enamel, rubber, paint, plastic layers, etc. on copper, aluminum, zinc, tin and other substrates.
The FN type coating thickness gauge adopts both the electromagnetic induction principle and the eddy current principle. It is a two-in-one coating thickness gauge of F type and N type.
How to replace the battery of coating thickness gauge
1 When the battery voltage is about 2.5V, the battery symbol will appear on the display and the battery needs to be replaced.
2 Open the battery cover and take out the battery.
3 Install the battery correctly according to the label on the battery box.
4. If the meter is not used for a long period of time, please remove the battery to prevent the battery from rotting and damaging the meter. The computer connection is as shown on the label on the battery box. The optional "USB data cable output", "RS232C data cable output" and "Bluetooth data cable output" can be used to communicate with the computer to achieve data collection, processing, analysis and Printing and other functions. Please refer to the online instructions for specific operations and install the battery correctly.
