This product is mainly used to measure the thickness of non-conductive coating on metal surface, as well as the thickness of non-ferromagnetic coating on ferromagnetic metal (such as iron, nickel, cobalt, etc.), such as paint thickness on automobile surface, coating thickness of metal parts and so on. This product also has built-in magnetic induction and vortex double principle probe, can 

  automatically identify the measured metal substrate, only need to be placed on the measured surface, can automatically calculate the thickness of the coating.

  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,ʺRelease 

  the up buttonʺ 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.
