How to use Reed TM-8811 Ultrasonic Thickness Gauge

With the Reed TM-8811Ultrasonic Gauge turned on, select the correct unit of measure by pressing the mm/inch button. Place the Ultrasonic sensor on the material surface being measured. Select the correct Material selection code and verify the coupling is okay by verifying that the Coupling indicator symbol is on. The reading on the display is the measurement value. The reading will be held until a new measurement is taken or until the unit is turned off.

To select the Sound velocity code, simply continue pressing the Plus or Minus buttons until you see a 4-digit number in the display. The 4-digit number represents the last sound velocity measurement taken. When selecting this velocity, you can measure the thickness of the same material as the last.

Measuring Sound Velocity – Press the “VEL” button and the display will show the last velocity measurement.
