3 OUTLINE CUTE 103 is Portable instrument designed with advanced features for Non-destructive Testing (NDT) of concrete quality by Ultrasonic Pulse Velocity (UPV) measurement method. Applications include estimation of properties of concrete such as strength, uniformity, crack depths, etc. CUTE 103 comes with our experience of over 20 years in design and manufacturing of UPV measuring instruments for concrete testing. Several new features are added over our earlier popular model CUTE102 series and it incorporates state of the art technology in the design. The instrument is designed to comply with the recommendations of BS EN :2004, ASTM C (re-approved 1979) and IS 13311(Part I); Description: CUTE 103 uses through transmission of ultrasonic pulses to measure the time taken to travel in the concrete under test. It consists of two Transducer probes, which are used interchangeably as Transmitter & Receiver during test. The Transmitter generates pulses of ultrasonic frequency, which are coupled into the concrete specimen under test. The receiving transducer is used to detect these pulses & to convert them back into electrical pulses. Suitable coupling media are used to minimize the losses due to acoustic mismatch at the transducerspecimen interfaces. A 10MHz Quartz time base ensures accurate measurement of pulse transit time (T) with a resolution of 0.1μS. Besides the use for basic measurement of Ultrasonic Pulse Velocity (UPV) in the concrete under test, the instrument can also be used for checking uniformity of concrete and for Compound measurement to estimate crack depth, when only one surface of the concrete is accessible for testing. Measurement log of max readings can be stored in the instrument memory. Each reading is stored with ID no., Date, Time & other parameters set during test. The waveform of the received signal can be viewed on the display during carrying out testing on site. This feature can be useful in verifying behavior of the Ultrasonic Signal in the concrete under test. These observations can help in estimation of compaction and uniformity of the concrete under test. 3

4 Canopus Instruments provides a Free Windows based Software Utility for communication of PC with the instrument using USB connection. This Utility allows user the following options. a. Download the measurement data stored in the instrument memory to the PC. This can be stored in File and can be Exported to EXCEL for report generation, trend analysis, etc. b. Live View of Measurement Waveform on the PC screen for analysis. This can be stored in File and can be used with other software for further analysis in Time domain or Frequency domain CUTE 103 is a fully portable model powered from external 5V DC adapter. It is provided with an Internal 3.7 VDC Li-ion Rechargeable Battery with in-built charger. Battery back-up time of more than 6 Hours is provided in continuous operation of the instrument. The battery icon on the screen indicates the battery charge level remaining so that the user is aware of the available back-up time during outdoor use. The Green OLED graphical display provides good readability even in the presence of bright ambient light. Graphical Icons on the display help in easy navigation of the user, without using a manual, for setting the instrument parameters using tactile keypad on the instrument front. The instrument is supplied with 54 KHz Transducer pair for normal concrete testing applications. Other values of Transducer frequencies are available as spares on request. CUTE 103 is small in size, lightweight & comes in a rugged cast aluminum enclosure suited for on-site use 4

7 Why use CUTE 103? For the Professional user, the instrument provides easy to use Quick key interface to test and record UPV test readings at site in a short time. It is small in size, lightweight & comes in a rugged cast aluminum enclosure suited for rough handling at site. The Transducers are made smaller and lighter in weight to provide ease of handling. The in-built Li-ion battery gives battery backup time exceeding 6 Hours in continuous operation, which can be more than doubled during actual use as the instrument is operated only while recording readings. Thus CUTE 103 is a very handy test instrument for Professional Concrete NDT applications. For the Researcher, the instrument provides several different test settings to carry out exhaustive testing procedures as demanded by the research work. Transducers of different Frequencies are available for specific needs. The USB interface along with On-line waveform viewing software package provides facility to view the test waveforms on a computer screen and SAVE them in a file, to be used with other software for further analysis in Time domain or Frequency domain. Thus CUTE 103 is an in-dispensable tool for research study of Concrete and other Composite materials. More so, CUTE 103 comes with our commitment of prompt & efficient after sales service to ensure proper upkeep and trouble free operation for years of use. 7
