Specifications: Probe: F probe, N probe Magnetic induction: Measuring principle(F), Eddy current effect(N) Measuring range: 0-2000um Precision: ±(3%+1um) Resolution: 0um-99.9um(0.1um) 100um-999um(1um) >1000um(0.01mm) Zero calibration: Support Statistics: Average, minimum, maximum, number Unit: um,mm,mils Minimum convex Radian: 5mm Minimum concave Radian: 25mm Minimum measured area: Diameter 20mm Minimum substrate thickness: 0.2mm 0.05mm Maximum measuring speed: 2 readings per second Power supply: 2*1.5V AAA battery(not included) Operating environment: Temperature 0-50°C, 20-90% rh (non-condensed) Preservation environment: Temperature:-10-60°C, 20-90% rh (non-condensation) Size /weight/material: 113mmX53mmX24mm/80g/ABS Measurement step: Step 1. Prepare the parts to be tested. Step 2. Stay away from the metal object at least 2 cm, press the switch key to turn on. Note: it is suggested that the instrument should be zeroed with reference to "zero calibration" before testing. Step 3. The probe is placed vertically and quickly on the surface to be measured until the drop is heard, and the measured value is displayed on the screen, and then the probe is lifted at least 2 cm away from the part to be measured, and the next measurement can be carried out. Note: if the automatic shutdown function is turned on and there is no operation within 3 minutes, the instrument will automatically shut down This machine has two calibration methods: 1. Basic calibration: the base calibration should be carried out when it is used for the first time, or has not been used for a long time, or when replacing the tested substrate material. There are 7 calibration points in the basic calibration, and the calibration unit is mm.. a. Prepare 6 pieces of standard film, the thickness of which is in0. 04 ~ 0.06,0.09 ~ 0. 11, 0.22 ~ 0.28, 0. 45 ~ 0.55,1. 90 ~ 1.05,1.90 ~ 2.00. b. First hold down the up key to hold, then press the on key, LCD full screen kettle display, and then hear a BI, LCD display Display 00mm, the lower right corner of the LCD displays the CAL character,Release the up button indicating that the calibration screen is entered. c. Press the probe lightly on the uncoated aluminum base, at which point the LCD displays 0.00, and then BI-BI calibrates twice. d. Get rid of the probe and show the number of 0.05mm on the LCD. The second number calibration is carried out, and the probe is gently pressed on the aluminum base where the calibration sheet is placed. After adjusting the value displayed on the LCD and the thickness of the calibration sheet by pressing the upper and lower keys, remove the probe and Bi-Bi-Sound, the second calibration point has been calibrated. Zero calibration: In order to improve the test accuracy, it is suggested that the instrument should be calibrated to zero. a. Preparation of uncoated substrate to be tested b. Hold down the right hand until you hear the drop, and the "zero calibration (ZERO)" on the screen will begin to flicker. c. The probe is placed vertically and quickly on the surface of the uncoated substrate to be tested. After hearing the dripping sound, the screen will display "0", and the probe can be lifted at least 2 cm away from the substrate, that is, to return to zero once.
