SMART SENSOR Ultrasonic Thickness Gauge This unit is an intelligent handheld product, which adopts ultrasonic measuring principle, and is controlled by micro processor, provides quick and precise measurement of thickness for most of industrial material. This unit is widely
used in various precise measurement for different hardware / parts in industrial realm; one of its important application is to monitor the level of thickness-decreasing during operation of various and pressure container. Diffusely
applied in manufacture fields, metal processing, and commercial inspection.

Scope of application  
This unit is suitable for measuring materials that are good ultrasonic conductor such as metal, plastic, ceramic, glass etc.,as long as the measured part in two parallel surfaces for measurement of thickness. This unit is not suitable for cast iron
due to its big crystalloid composition.

Operation Guide

 

1. Before measurement

 (1) Connect the transducer with the main unit, press ON/OFF to turn on,LCD display full screen for 0.5 second with backlight,then vertical  bar is displayed

 twice circularly, meanwhile the main display area show 0000 to 9999 progressively.After that, LCD display the last applied sound velocity with registered

 memory unit, indicating the gauge is ready for use.

850-0_

 

 (2) Sound velocity selected & adjustment Press “VEL” to enter sound velocity interface, press “VEL” again, you can select reserved velocity data by pressing

 “850-2_ ” or “850-3_” with the word “VEL” blinking on LCD ; If you need to adjust sound velocity data, press “VEL” once more, the “VEL” and “m/s” will keep blinking,

 indentifying the unit is on adjusting status. Then, increase or decrease the sound velocity to the data you want by pressing “850-2_ ” and “850-3_ ”,and this data will

 be automatically stored into current sound velocity memory unit. After that, press “ VEL” to confirm new sound velocity, and the icons of “VEL” and “m/s” stop

 blinking.

850-4_

 

 

 2. Calibration
 A calibration should be made for every replacement of transducer or batteries, this operation is sufficiently important to assure the measuring precision.

 If necessary,this step should be repeated. Pressing “CAL” for 2 seconds, LCD displays “CAL”, indicating that the unit is on calibration status, vertical bar

 displayed circularly on the left of LCD. put few provided coupling agent on the stan-dard sample block to couple the transducer and the sample block. Until

 the LCD display 4.0mm indicating the calibration is completed. After calibration, sound velocity will back to your selected value, and ready to measurement.

850-5_

 

 3. Thickness measurement
 Put the coupling agent on the area to be measured to couple the transducer with the hardware/workpiece, LCD will display the thickness reading.

 Notes: 860-12 icon on the screen indicates a well coupling, if the icon flashes or not shows that means a poor coupling. After remove the transducer, the reading

 will be hold.

850-6_

 

 4. 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 850-2_or850-3_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.

850-7_

 

 5. Data storage
 (1) Keep pressing STORE for 2 seconds to enter save thickness data mode, LCD display THICKNESS, mm, M icon with first memory unit. If the first memory
 unit is not being registered, so LCD will display 0.0.
​​​​​​​ (2) Press 850-2_ or 850-3_to select your desired memory unit (1-10).
 (3) After picked up the memory unit, it will begin to work. While measuring, the memory unit NO will flash and the new

 measurement will be renew the memory unit, when the measurement completed, the last reading will be stored in the selected memory unit automatically

 with the memory unit NO stop blinking.

850-8_

 

 6. Review the saved data
 Press the memory unit NO and stored data displayed. You can review the saved data in 1-10 units by pressing “850-2_ ” and “850-3_ ” and they are read-only. Press

 “STORE” will back to measurement mode.

850-9_

 

 7. Low battery indication

 When 850-10_ icon flashes, please replace the batteries for further measurement.

 8. 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 operation will turn on the back light for

 7 seconds until press ON/OFF to turn off the unit. If no any operation for 2 minutes, the gauge will turn off automaticly and the back light function will be

 cancelled.
