Gain - Variable adjustment

—

Low, Standard, High

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. TKG250 also has file compare & grid review features.
