1. A combination of vibration monitor and vibration diagnostic instrument, comprising:
- a vibration monitor located at a rotating machine, comprising;
a vibration sensor;
a memory having stored thereon an alarm threshold value, wherein the value is based upon machine parameters;
a processor coupled to the memory and the vibration sensor and configured to process data acquired by the vibration sensor to determine if the alarm threshold value has been reached; and
a communication module coupled to the processor and configured to receive the alarm threshold value and send an alert signal when the alarm threshold value has been reached; and
a vibration diagnostic instrument at an external location from the vibration monitor, comprising;
a user interface for receiving operational parameters of the machine;
means for processing the operational parameters and determining one or more alarm threshold values; and
means for downloading the alarm threshold values to the vibration monitor.

Abstract
A user provides relevant information about the parameters of a machine to be monitored to a vibration diagnostic instrument. The user also specifies a location of the machine to be monitored, an alarm level to be set, and the type of alarm to be sent. The instrument then automatically generates appropriate alarm thresholds and transmits the information to a removable stand-alone monitor. The stand-alone monitor acquires vibration data about the machine and sends the appropriate alerts when an alarm threshold has been reached.
