The DLD100 combines the power­ful advantages of digital design with the detailed dynamic echo informa­tion that was previously only possible with an analog display. The high resolution color LCD display, 160 Hz update rate, and “single shot” measurement tech­nique produce a fast, smooth response for immersion and critical weld testing.

 
The quality, durability, dependability and ease of use remain on the DLD100. From rugged field inspections to high resolu­tion thin measurements, long acousti­cally clean materials, and immersion systems work, the DLD100 extends the range of applications that a portable instrument can perform.

Parameter Setups Files	Up to500 files stored instrument parameter setups.

Alarm	Selectable positive logic, negative logic, upper limit thickness or lower limit thickness alarm mode
Curved surface correction	Corrects sound path information when using an angle beam transducer to circumferentially inspect a curved surface for either tubular or bar inspections.
Auto Calibration	Measurement and setting of sound velocity and probe delay using two known calibration echoes (2-point calibration)
Auto Gain	Adjust automatically the system sensitivity to bring (increase or decrease) the measured echo to the suitable echo height. Echo height setting value from 10 % to 90 % of the screen height.
