LCD back light & Automatic power off Before turn on the gauge, hold pressing CAL , and press ON/OFF button to turn on, the back light will active, every will turn on the back light for 7 seconds until press ON/OFF to turn off the unit. If no any for 2 minutes, the will turn off automaticly and the back light function will be cancelled.
Sound velocity measurement With a given thickness to read out sound velocity of material: Obtains the thickness of material by using vernier caliper / micrometer, then couple the transducer with that sample material until a reading displays on the LCD, remove the transducer and press or to adjust the reading match the thickness by caliper/mirometer, then press VEL to display the sound velocity and save in current velocity memory unit.
Auto linear compensation: this advanced software program enhances the by correcting the non-linear accuracy of transducer. Use and keys to make a quick adjustment for the sound velocity /thickness,and a quick recall to the stored data.
Coupling status indication: Observing the coupling to learn if the coupling is accomplished or not. 10 thickness measurement storage and recall function is available. Auto calibration to assure the accuracy.
the saved data Press the memory unit NO and stored data displayed. You can the saved data in 1-10 units by pressing and and they are read-only. Press STOREwill back to measurement mode. Low battery indication When flashes, please replace the batteries for further measurement.
