  • Page 30: Vibration Pickup Placement And Connection

    Preparations Vibration pickup placement and connection Vibration axis Environmental vibrations are normally measured in two horizontal planes (front/back and left/right) and one vertical plane. This means that complex vibration phenomena are reduced to three axes (X, Y, Z), for easier observation. The axes are defi ned as follows (facing the vibration source).
  • Page 31 Preparations Vibration Pickup placement Install the sensor on a solid horizontal plane. As necessary, fasten the sensor with bolts on the vibrating surface. Important Avoid locations exposed to direct sunlight or to drastic temperature changes. Such condi- tions can cause changes in Vibration pickup sensitivity, which will impair the accuracy of measurement results.

  • Page 110: Command

    There are two types of commands: setting commands and request commands. Setting command This type of command serves for changing the VM-56 status or mea- surement parameters. Only some commands of this type will produce a response from the VM-56. The response consists of status information returned after the setting command has been processed.
