Badger Basket WT-2 User manual - Known Thickness
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.
OTEE:
N
Every 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
. 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.
