PX-7 Ultrasonic Thickness Gauge

Selecting Measurement Mode

The PX-7 is equipped with four measurement mode options (echo-

echo, interface-echo, auto, or plas). In echo -echo mode, the gauge has the

ability to read thin metals down to .006 inches (.15 millimeters). The echo -

echo mode also allows the user to measure the thickness of metals that

have been previously coated or painted on the surface. This enables the

user to determine the thickness of the metal without having to remove the

paint. In interface-echo mode, the gauge has the ability to read plastics

and thicker materials. The PX-7's auto mode will automatically switch

between echo-echo and interface-echo according to the different materials

being measured. Finally, the plas mod can be used to measure thin plastics

using a special graphite tip. The following section outlines how to switch

between measurement modes:

Measurement Modes

1) Make sure the PX-7 is on.

2) Press the UP arrow key to toggle between measurement modes.

The gauge will display GatE followed by I-E, E-E, Auto, or PLAS

depending on which mode the PX-7 was last used in.

3) Repeat step 2 until the desired mode has been displayed.

Note: Once the mode has been selected, the user can use the built-in

LOC feature to prevent additional users from accidentally changing

the mode. When the PX-7 is in LOC mode, all features (with the

exception of the calibration and units), are locked and cannot be
