Programming the Sound Velocity

Since the MX-2 is a fixed velocity gauge with 8 factory set material

types, correct sound velocity for the material being measured must be

selected using one of the 8 materials in the MX-2, or programmed into the

gauge via the serial port on the bottom of the unit. Approximate sound

velocities for common materials can be found in appendix C .

Programming the MX-2

1) Connect the serial cable (Part No. N-306-0010) to a COM port on

a computer and to the RS232 connector located on the bottom of

the MX-2. Remove and replace the rubber plug before and after

programming.

2) Assuming that DakView2 PC software is installed and running,

select the MX-2 icon from the DakView2 gauge selector icons. A

window will appear with the title “MX-2 Velocity Upload Utilty”.

3) Under the Preset Velocity heading are two options. The first

option is a test box with a velocity number displayed. The text box

is editable. To change the velocity, click in the text field and type in

the appropriate velocity number. The second option is a list box

with a material type displayed. To change the material type, click

the down arrow located to the right of the list box. Use the arrows

or slider bar to scroll through the available material types. Click on

a material to select it. Note: Both velocities can be edited and

uploaded into the MX-2 at the same time.
