398.9 Velocity (VX)When the velocity setting (VX) is enabled, the ZX-6 will display will the materialvelocity as the primary measurement quantity instead of dimensional thickness. Thefeature is generally used for basic “nodularity” testing, as velocity is a key part ofdensity for determining hardness. An example might be casting manufacturerswhere the density/hardness will determine the strength of the material.When this feature is enabled, the ZX-6 is operating in reverse to the standard optionof the gauge. Only the ‘one point’ calibration can be used with this feature active,and a manual or auto zero is still required. The ZX-6 can be calibrated by enteringthe known velocity or entering the know thickness of the material at a given positionon the test material. Refer to the ‘making measurements’ section on page 27 for acomplete explanation of the zero and one point calibration procedure.The procedure to enable the velocity feature is outlined below:Velocity Gauge1) Press the key to access the menu items/features.2) Use the keys to scroll through the items/features until theVX feature is being displayed.3) Press the key to edit the setting. The edit icon will be illuminated andflashing.4) Use the keys to select the on/off option.Note: Pressing the key prior to pressing the key will abort to themeasurement screen without saving changes.
