MITECH Instrument
MFD500B - 1

Display
Hi-resolution ( 320× 240 pixels) multi-color TFT LCD with 4 user-selectable
brightness control provides high contrast viewing of the waveform from bright,
direct sunlight to complete darkness.
The hi-resolution multi-color TFT LCD display with fast 60 Hz update gives an
? analog look? to the waveform providing detailed information that is critical in
many applications including nuclear power plant inspections.
Range
Up to 9999 mm in steel. suitable for use on large work pieces and in
high-resolution measurements.
Pulser
Pulse Energy selectable among Low, Medium and High.
Pulse Width tunable from 0.1µ s to 0.5 µ s to match the probes with different
frequency.
Pulse Repetition Frequency adjustable from 10 Hz to 1 KHz in 1 Hz increments.
Damping selectable among 100©
200© and 400© for optimum probe
performance
Test Modes include Pulse echo, dual and thru-transmission
Receiver
Sampling 10 digit AD Converter at the sampling speed of 160 MHz
Rectification Positive Halfwave, Negative Halfwave, Fullwave and RF
Analog Bandwidth: 0.5MHz to 15MHz capability with selectable frequency
ranges ( automatically set by the instrument) to match probe for optimum
performance.
Gain 0 dB to 110 dB adjustable in selectable steps 0.1 dB, 2 dB, 6 dB, and locked.

Gates
Gate Start: Variable over entire displayed range

Functions
Semiautomatic two point calibration: Automated calibration of transducer zero offset and/ or material velocity
Flaw Locating Live display Sound-path, Projection ( surface distance) ,
Depth, Amplitude,
Flaw sizing: Automatic flaw sizing using AVG/ AVG or DAC, speeds reporting of defect acceptance or rejection.
Digital Readout and Trig. Function: Thickness/ Depth can be displayed in digital readout when using a normal probe and Peam path, Surface Distance and Depth are directly displayed when angle probe is in use.
Both the DAC and the AVG method of amplitude evaluation are available.
Curved Surface Correction feature
Crack Height Measure function
Weld figure feature
Magnify gate spreading of the gate range over the entire screen width Video Recording and play Auto-gain function
Envelope: Simultaneous display of live A-scan at 60 Hz update rate and envelope of A-scan display
Peak Hold: Compare frozen peak waveforms to live A-Scans to easily interpret test results.
A Scan Freeze Display freeze holds waveform and sound path data B Scan display feature
Real Time Clock

The instrument clock keeps running tracking the time.
Communication
High speed USB2.0 port.
The optional DataPro software helps manage and format stored inspection data for high-speed transfer to the PC. Data can be printed or easily copied and pasted into word processing files and spreadsheets for further reporting needs. New features include live screen capture mode and database tracking.
