Operation manual Operation manual Reference block for functional tests Power charger Optional transducers (if ordered) Warranty certificate Calibration certificate Description and operation of the instrument The present operation manual (from now on referred to as "operation manual") contains: · technical specifications, · description of design, · and operation principle of the А1207 Ultrasonic Thickness Gauge (from now on referred to as "thickness gauge" or “instrument”), · as well as information required for proper working with the instrument. Carefully read the operation manual before...

Operation manual Operation manual 1.2.1.2 Operation conditions The instrument is designed to work under the following conditions: · ambient air temperature ranges from - 30 to +50 С; · relative air humidity up to 95 % at +35 С. Technical specifications The table below lists the main instrument parameters. Table 1: Key instrument parameters Parameter Measurement range of the thickness (steel), mm from 0.8 to 75.00 (double-crystal transducer) Sampling rate of the thickness indication, mm: from 0.80 to 9.99 mm from 25 to 100.00 (double-crystal transducer) 0.01 0.1 Setting range of ultrasound...

Operation manual Operation manual 1.2.3.1 Instrument design А1207 Ultrasonic Thickness Gauge is a pocket-type one-piece case (see figure below) with a built-in accumulator battery and a built-in double-crystal transducer or singlecrystal transducer (if requested). Capsule of the piezoelectric transducer Tuning keys Digital display The instrument's design allows the replacement of the worn-out capsule of the built-in transducer by unscrewing the tip detaching the transducer capsule from the instrument without extra tools (see Replacement of the transducer capsule 14 ). The · switch the...

Operation manual Operation manual Thickness measurement result Accumulator charge level Measurements units Operation principle The instrument measures the time of the double movement of ultrasonic pulses through the inspected object from one surface to another. This time is converted to the thickness value using a known velocity value. The piezoelectric transducer integrated into the instrument’s case sends ultrasonic pulses into the inspected object and receives their reflections. The transducer is put on the surface of the tested object in the point where the thickness should be measured....

Operation manual Operation manual layer (0.1-0.3 mm). At that, the result of the measurements will include the thickness value of the paint layer. If there is a thick layer of paint on the surface or the paint starts to pill off, then remove it since the thick paint layer reduces the signal and can produce a false echo resulting in false measurement results. Putting the piezoelectric transducer onto the surface The piezoelectric transducer should be tightly pressed to the surface of the tested item to provide a good transmission of the ultrasonic sound into the material. When measuring the...

Operation manual Operation manual by the relatively big size of the grains and by the anisotropy of the sound velocity with respect to the grain orientation. Making the instrument ready for operation Surface preparation Carefully clean the surface of an inspected object from dirt, friable rust, and scale before measurements. Apply a sufficient amount of the lubricant to the area of inspection. Switching On/Off the instrument To switch on the thickness gauge, shortly press the On the instrument's screen, a moving message with the manufacturer name and firmware version is displayed for...

Operation manual Operation manual 1.3.3.4.1 Current ultrasonic sound velocity To view current ultrasonic sound velocity (see figure below) shortly press (hold no longer than 2 seconds) the key while in the measurement mode. 1.3.3.4.2 Edit current ultrasonic sound velocity To edit the current ultrasonic sound velocity value, do the following: · press (hold longer than 2 seconds) the or key while in the measurement mode, at that the current velocity value will start blinking; · set the required velocity value using the or key; The velocity value will stop blinking in three seconds, and the...

Operation manual Operation manual The velocity value will stop blinking in three seconds, and the instrument will switch to the measurement mode. At that, the measured velocity value will be saved. If there is no material sample, though the tested item is accessible from both sides, you can measure its thickness in the place convenient for inspection (using a micrometer), and then adjust the instrument in a way similar to adjustment using a sample of known thickness. 1.3.3.4.4 Calibration mode For a single-crystal transducer, calibration mode consists of two stages. The first stage is...

Operation manual Operation manual After calibration on the 5 mm for a single-crystal transducer or 25 mm for a doublecrystal transducer the determined velocity value in the instrument is shown on the display. The determined velocity value by the calibration procedure is not saved in the device memory! Notice the velocity value and manually set it in the instrument if needed! The maintenance of the instrument includes cleaning it from dirt and dust and recharging the accumulator. Accumulator battery The rechargeable battery of the instrument is designed for operation over a wide range of...
