Where the supply of Zhanjiang, Maoming has sold the film thickness gage galvanized equipment distributor where the sale, where the production of galvanized gage, galvanized gage price, brand gauge galvanized, galvanized gage configuration, galvanized thickness measurement range, precision gage galvanized coating thickness gauge first chapter is a professional measuring metal surface for coating thickness of the cover layer objects professional non-destructive testing instruments. It uses the following different methods in accordance with different measurement metal substrate. A, the magnetic thickness measurement method, non-destructive measurement of magnetic metal substrates: Thickness (such as steel, iron) non-magnetic coatings (eg: zinc, chromium, indium, enamel, rubber, powder, paint, electrophoresis, enamel , coating, spray coating, etc.) B, eddy current thickness measurement method, non-destructive measurement of non-magnetic metal substrates (such as: non-conductive coating thickness of aluminum, copper, stainless steel) (eg: paint, powder, plastic, rubber, enamel, enamel, electrophoresis, coating, etc.) DR260 models have features A above; also known as: magnetic coating thickness gauge, the instrument used: GB / T 4956-1985 standard (magnetic method) DR270 models have above function of B; also known as: eddy current coating thickness gauge, the instrument used: GB / T 4957-1985 standard (eddy current method) DR280 model has all the functions of the above A and B, known as: dual coating thickness measurement instrument, the instrument used JB / T 8393-1996 standard instrument uses widely used in coating industry, manufacturing, metal processing industry, chemical industry, commodity inspection and testing fields. Chapter l Instrument features simple operation, test speed, good sensitivity, high accuracy measurement l have two test methods: continuous (CONT INUE) and single (SINGLE) measurement l There are four statistics: Maximum ( MAX), minimum (MIN), the mean (MEA), the number of measurements (No) l large capacity storage, can store more than 800 measurement data l connect the computer to communicate, read out the stored data is saved or printed (for U-type host) l There are two calibration methods: l zero calibration point calibration procedure and has beep marked (single measurement mode) l automatic identification of iron-based and non-ferrous base metal l metric conversion μm / Mil l Large backlit LCD display mode, low voltage indication l manual / automatic shutdown function Chapter III technical parameters A, measuring range: 0-1250 / 3000μm (more than 1250μm in advance to tell manufacturers customized separately) B, use of the environment: Temperature: 0 ℃ -50 ℃, Humidity: 20% RH-90% RH, the absence of a strong magnetic field environment using C, thinnest substrate: 0.4mm D, measurement accuracy: ± (1% -3%) + 1.5μm E, Resolution: 0.1 μm / 1μm (100μm following is 0.1μm, 100μ above is 1μm) F, the minimum base area 10 * 10mm G, the minimum curvature: convex 5mm; concave 25mm H, Dimensions: 130mm * 70mm * 24mm I, Weight: 100g J, Power supply: three (7) Chapter alkaline batteries Screen Display Method Description Chapter instrument after instrument battery installed, press the "" button to boot, so after the buzzer sounds, the LCD display, the instrument automatic measuring mode, the probe vertically directly and quickly pressed onto the surface of the coating thickness, the instrument automatically measured by the probe coating thickness, and the thickness value is displayed by the display out (figure: current diagram shown as the current measurement result 102um, measurement times: 20 times). (Note: Note the measurement probe remain vertical) mode conversion Chapter 6.1 metric conversion: μm / Mil, the instrument defaults to metric units μm; such as the need to convert to English: Mil, as follows: After the instrument is switched into the measurement state Press the button, you can convert the unit: mil 6.2 inch two test modes: namely, continuous (CONT INUE) test mode and single (SINGLE) 6.2 .1 measurement mode measurement mode conversion: Instrument default test mode for continuous (CONT INUE) test mode; the probe vertical pressure on the measured object, the instrument of the points automatically and continuously test, measurement results and the number of measurements in the LCD display readings; if you need to convert a single (SINGLE) test mode operation as follows: In the shutdown mode by simultaneously pressing the "" key and the "" key, the first release, "" and then release the "" button, then the instrument test mode for a single test mode can be tested directly. Chapter VII of the statistical functions 7.1, when measured at the lower right corner of the LCD displays the number of measurements, measurement times up to 999 times. 7.2, four statistical values: Maximum (MAX), minimum (MIN), the mean (MEA), press the button, you can take turns reading the statistics. Chapter VIII instrument delete all the data stored in the off state of 8.1 while pressing the "" key and the "" key, the first release, "" and then release the "" key, you can delete all the measurement data storage equipment. 8.2 can also delete data through software, specific operations, see the software instructions. (For U-type machine with software version) Chapter IX instrument calibration (operation when the instrument measuring error, or need calibration) 9.1 zero calibration, the probe vertically quickly pressed on an empty matrix does not let go, and then hold down zero key "", then there will be a beep, is displayed on the screen until "CAL", then lift the probe, zero success; then the instrument can take the test piece (specific operations, see fifth point) . (Such as school zero head pressure is not measured on an empty matrix, then the zero calibration failure, the test will not be required to correct the instrument zero to normal use) 9.2-point calibration steps:? Calibrate zero. Steps:? Well zero after school, according to the measurement of coating thickness, choose a relatively close to the standard value of the film coating thickness of the workpiece, the diaphragm on the air base, the probe will measure the vertical pressure down quickly, if test out the value of the diaphragm has a small error, you can "" "" button to fix the probe after the lift. (Note: When corrected, lift the probe) [Note: because the material provided by the manufacturer of the matrix (ie, iron or aluminum) may now not exactly user base piece, that zero is different, so you want to measure results more most When accurate, it is recommended to find a workpiece material and the same substrate (no Coating substrates) do zero calibration, then measure. ] Chapter restore the factory settings the user during use, can not be tested or when there is a large error, you can restore the factory settings. Operating with the following: In the off state while holding down the "" key and the "" key, then the first release, "" key, then release the "" key, the screen on the left will look Fe and NFe in turn display, which indicates recovery The factory setting is successful, you can then boot off the normal tests. Chapter XI an instrument maintenance, instrument storage temperature: 0 ℃ -40 ℃, relative humidity ≤85%, when the instrument is not in use, remove the batteries, periodically clean the probe and diaphragm. 2, away from strong magnetic fields, oil, heavy dust, damp place to prevent collisions. Frequently Asked Questions 1. coating thickness normal boot, but the test did not respond? A: The first rule is empty zero calibration, re-zero to normal operation (see Chapter IX operation). 2. Test data error value is large, or how to deal with the chaos of data transfer? A: The first colonel in the empty matrix to zero, then the standard patch test on a substrate, such as the emergence of small errors, ie press the "+" "-" key to fine-tuning. When the error value is large, you can directly restore the factory settings (see Chapter 10).
