 SV- MFD800C  Portable ultrasonic   crack tester   Summary The MFD800C is an advanced digital ultrasonic flaw detector featuring a multi-color TFT LCD and a host of new features to meet challenging inspection requirements. It combines powerful flaw detection and measurement capabilities, extensive data storage, and the ability to transfer detailed inspection data to the PC via its high-speed USB port. The instrument incorporates many advanced signal processing features including a 15MHz RF bandwidth to permit testing of thin materials, narrowband filters to improve signal to noise in high gain applications, a spike pulser for applications requiring higher frequencies, and a tunable square wave pulser to optimize penetration on thick or highly attenuating materials. Functions & Usage The instrument can be widely used in locating and sizing hidden cracks, voids, disbands, and similar discontinuities in welds, forgings, billets, axles, shafts, tanks and pressure vessels, turbines, and structural components.   Specifications Range: 0 to 9999 mm, at steel velocity Material Velocity: 1000 to 9999m/s Display Delay: -20 to 3400µs Probe Delay/Zero Offset : 0 to 99.99µs Sensitivity: 110 dB max in selectable resolution 0.1, 1.0, 2.0, 6.0 dB and locked Test Modes: Pulse echo, dual element and thru-transmission Pulser: Tunable Square Wave Pulser Pulse Repetition Frequency ranges from 10 Hz to 1000 Hz Pulse Energy: 200V, 300V, 400V, 500V, 600V selectable Bandwidth (amplifier bandpass ): 0.2 to 20 MHz Gate Monitors: Two independent gates controllable over entire sweep range Rectification: Positive half wave, negative half wave, full wave, RF System Linearity: Horizontal: +/-0.2% FSW, Vertical: 0.25% FSH, Amplifier Accuracy +/-1 dB Reject (suppression): 0 to 80% full screen height Units: Inch or millimeter Transducer Connections: BNC or LEMO Power Requirements: AC Mains 100-240 VAC, 50-60 Hz Operating Temperature: -10°C to 50°C Storage Temperature: -30°C to 50°C   Operations & Notes Clean the instrument and its accessories using a moist cloth.
