MATERIAL SELECTION

1. Press either Power switch to turn on the unit.

2. Press SELECT. The display shows the code cdxx or xxxx. The cd is an abbreviation for code and xx is a number between

01…11 corresponding to a particular pipe material. xxxx is a four-digit user-dened material sound velocity.

3. Press or to select the correct pipe material code then. Press SELECT to conrm. The display shows 0. If you select a

material code but do not conrm the selection, the code automatically changes to 0after several seconds. The meter saves

the material code before exiting.

OTE:NIf you press while displaying cd11 or cd01, the last user-defined sound velocity displays.

OTE:NYou do not have to select the material code once the code is stored to memory unless you need a new

material choice.

4. To browse the material code choices, press SELECT and then use or to scroll through the list. To stop browsing and

make a material selection, press SELECT again. The code changes back to 0and returns you to the measurement mode.

CALIBRATION

1. Place a small amount of couplant on the calibration stage.

2. Press CAL. The CAL indicator appears on the display.

3. Press the face of the transducer to the calibration stage. The coupling icon appears if the connection between the

transducer and the calibration stage is established. 0.197 inch or 5.0 mm and CAL alternate on the display. When the

alternation stops, press CAL to conrm. The unit automatically returns to measurement mode.

OTE:NThe unit saves the calibration result automatically once confirmed. It is unnecessary to calibrate often unless the

accuracy of measurement is suspect.

MEASURING PROCEDURE

1. Press either Power switch to turn on the unit.

2. Press Inch

mm to select the desired measurement unit.

3. Select the correct pipe material code. See Table 1.

4. Place a bead of couplant on the pipe surface.

5. Press the transducer onto the pipe surface to make a measurement. The display shows the wall thickness value.

6. Verify that coupling is established and the coupling icon is on (see Figure 1).

OTE:NThe reading is held until a new measurement is made or until the power automatically turns off.

OTE:NTo turn o the power, press either of the power switches or wait until the power automatically turns o after a period

of inactivity.

MEASURING USING A KNOWN VELOCITY

1. Press VEL. The display shows the last pipe sound speed velocity used.

2. Set the known pipe velocity by pressing or in velocity mode.

OTE:NEvery press increments or decrements the velocity by 32.8 fps (10 mps). To change the velocity in 328 fps (100 mps)

jumps, press and hold or for more than four seconds.

3. Place a bead of couplant on the pipe surface.

4. Press the transducer onto the pipe surface to make a measurement.

5. Verify that coupling is established and the coupling icon is on (see Figure 1). As long as the pipe's sound speed is set

correctly, the reading on display is the wall thickness of the pipe.

MEASURING AN UNKNOWN WALL THICKNESS USING A SAMPLE OF

KNOWN THICKNESS

1. Using a sample pipe of known thickness, obtain the pipe's sound speed value by incrementing or decrementing the sound

speed value until the wall thickness reading matches the known thickness value.

2. When the thickness values match, the velocity reading is the actual sound speed for the pipe sample.

3. With the known velocity for that pipe type set, measurement of the wall thickness of any pipe of the same type can

be done.

BATTERY REPLACEMENT

1. When the battery symbol appears on the display, it is time to replace the batteries.

2. Slide the battery cover away from the instrument and remove the used batteries.

3. Install fresh AAA batteries, paying careful attention to polarity.
