1.NOTE
Default:
Colors: black and white.
Measurement range: 0–2000μm.
Power supply: 2 × 1.5V AAA batteries.
Probe modes: AUTO, Magnetic Induction (F), Eddy Current (NFE).
In AUTO mode, the device auto-detects and switches probe modes.
F mode is for coatings on ferromagnetic substrates.
N mode is for coatings on non-ferromagnetic metal substrates.
Substrate types: Fe = ferrous metal, NFE = non-ferrous metal.
Display type: LED.
Supports zero-point calibration.
Provides average, minimum, maximum values, and measurement count.
Units supported: μm, mm, mils.
Features auto power-off.
For better accuracy, perform zero calibration before measurement.
Basic calibration is recommended when first using, after long storage, or when changing the substrate.
Mainly used for measuring non-conductive coatings on metal surfaces, and non-ferromagnetic coatings on ferromagnetic metals (e.g. iron, nickel, cobalt).
Due to page limitations, some parameters may not be fully listed.

5. FAQs
Q1: Can the device automatically detect the base material?
A1: Yes, in AUTO mode, it automatically identifies ferrous (Fe) or non-ferrous (NFE) substrates and selects the correct measurement method.
Q2: When should I calibrate the device?
A2: Calibration is recommended before first use, after long periods of inactivity, or when changing the type of substrate.
Q3: Is it suitable for measuring coatings on aluminum?
A3: Yes, use the NFE (eddy current) mode for non-ferrous substrates like aluminum.
