2.5.3 Calibrating by Material Velocity (PROBE&CAL - VELOCITY)

When calibration blocks/pieces are not available, or a procedure requires a specific material velocity to be used during an ultrasonic wall thickness test, the DMS Go can be calibrated by adjusting the material velocity.

1.

In the

MAIN menu, scroll to the PROBE & CAL submenu using the joystick (

).

2.

Move the joystick ( ) to view

VELOCITY, the calculated velocity after the calibration is shown. Move the joystick (

) to change the velocity. If you see VELOCITY in capital letters, it indicates that you are using a preset velocity from the internal material table, while velocity in lower case letters appears when you have fine-tuned the velocity or performed a calibration that adjusted the velocity.

3.

Press F3 or F4 key to open a preprogrammed list of material velocities, and continue pressing those keys to scroll through the list.

Adjustments in increments of 1 are made with the joystick.
