Preparation for measurements

  1. Press the POWER button to turn the meter on.
  2. Check that the display is on and that the low battery icon is not on.
  3. If the low battery icon appears, replace the batteries.
  4. Attach either the sensing head or the magnetic base by screwing it into the vibration sensor.

Measurements

  1. Press the MODE button to step through and set the function (velocity or acceleration) and the units desired.
  2. For non-ferrous surfaces, gently hold the meter (as shown) with the sensing head against the vibrating surface.
  3. For ferrous surfaces, attach the meter to the surface with the magnetic mount.
  4. The meter must be held perpendicular to the surface to maintain measurement accuracy
  5. Read the measured value in the display.
