Ultrasonic Thickness mainly consists of two parts, the host and the probe. Host circuit includes a transmitter circuit, a receiver circuit, counter display circuit of three parts, high-pressure shock wave generated by the transmitter circuit excitation probes, generating ultrasonic transmit pulse, pulse after reflection by the media interface receiving circuit for receiving, processing through the MCU count by the thickness of the liquid crystal display value, which is mainly based on acoustic wave propagation velocity in the sample multiplied by half the time obtained by the thickness of the sample specimen. Easy to use 456 coating thickness of 1 to boot. 2. Press the "Calibration" button (leftmost), select "calibration method" in the menu → "Rough / two" smart gauge, press the "Select" button, the meter prompts "recalibrate it now?", Press " Yes "to start the calibration. 3. The display appears on "Calibration step 1: the probe on the thickness of the calibration sheet or press Next", according to this prompt manufacturers to gauge the probe on the thicker calibration sheet (eg 125um membrane), and by ↑ ↓ keys to adjust the values ??or the calibration values ??to the diaphragm. Then press "Set." 3. The display appears on "Calibration step 2: the probe calibration on the thin sheet or press next," according to this prompt, the probe calibration on a thin sheet (for example 25um diaphragm), and the ↑ or ↓ key to adjust the value to the diaphragm calibrated value. 4. At this point calibration is complete, the instrument will prompt "test", a test with a known thickness of the diaphragm, if indication error to less than 3%. If the error is large, you can re-calibrate. Precision Thickness Gauge | Thickness | Branch instrumentation provided by the Qingdao Branch of the Instrument Co., Ltd.
