Specifications	Range
Steel Thickness Range	5MHz probe: 0.040 to 20'' (1.0 to 508mm); 10MHz probe: 0.030'' to 2'' (0.76mm to 50.8mm)
Material velocity calibration range	0.200 to 0.7362 in/μS (0.508 to 18.699mm/μS)
Languages	English, French, Spanish, Italian, Czech, German, Portuguese, Slovak, Finnish, and Hungarian
Hold Mode	Holds display to retain last thickness reading with reverse video display
Freeze Mode	Freezes display (ideal for high temperature readings)
Fast Min/Max Mode	Displays Min or Max and actual thickness value at 20 measurements/sec
Units	Inches/Millimeters/Microseconds
Alarms	Audible beeping; illuminae flashing display and keypad; and vibration feedback
Illuminating Keypad	F1 = Red, F2 = Yellow, F3 = Green for easy, go/no-go testing
Gain - Variable adjustment	In 1dB steps from 20-90dB or Automatic Gain Control (AGC) for waveform
B-Scan - Displays a cross section of the test piece	Displays a visual cross section of inspection area with no correlation to distance. B-Scan alarm colors consist of: Red = below minimum/above maximum; Yellow = Caution; and Green = Good.
Echo to Echo	Measure the metal thickness only (paint & coatings do not affect base material thickness value)
Differential Mode	Displays the difference from the actual thickness measurement and a user entered reference value
Velocity Mode	Displays acoustic sound speed to measure thickness of unknown materials
Datalogger	Stores 50k readings (expandable to 100k) and 5,000 waveforms; file names up to 20 characters long; and the included Extech XPorter software extracts .csv data files that can be opened for viewing in MS Excel, Notepad, or Wordpad. File compare & grid review
Range	Adjustment of manual range control or auto zoom tracking to center echoes independent of selected range
Rectification Modes	RF, Half Wave Positive, Half Wave Negative and Full Wave Rectification
Live Waveform (A-Scan)	Full adjustments for gain in 1dB step or AGC, main bang blank, blank after first received echo, range including zoom auto tracking to center echoes independent of material and rectification
Battery Life	8 to 14hrs (depends on operating conditions)
