Motor Testing Tip
The Importance of Backing Up Data
The importance of backing up data cannot be overstated. After figuring out how to test motors, setting up a predictive maintenance program and spending a lot of staff hours to test the motors only to lose the data is detrimental to business. Data lose will not only cost time, but it will also cost information and the history of each motor. Spending a few minutes at frequent intervals backing up data will be time well spent. Data collected carefully and meaningfully gives a picture of the history of each motor and is an asset in determining the health of the motor. SO BACK IT UP!!!!

Accelerometer Installation Tip: Avoiding Ground Loops
In order to provide proper shielding and prevent ground loops, shield and common grounding should be carefully considered. Ground loops are developed when a common line (i.e. signal return/shield) is grounded at two points of differing electrical potential.
For sensors with coaxial cable, the center conductor carries the signal and power, while the outer braiding provides the shielding and signal return. Normally the cable shield is electrically isolated from the sensor housing. This isolates the shield from the mounting point of the machine and prevents ground loops. If a non-isolated sensor is used, it is recommended that an isolated mounting pad be used to break up possible ground loops.
For sensors using two conductor/shielded cable, the signal and power are carried on one lead and the signal common on the other. The cable shield serves to protect the signal from ESD and electromagnetic interference. The shield should be grounded at only one point, normally to the readout equipment.
NOTE: In all cases, it is very important that the cable shield terminations be properly grounded. Failure to do so in high EMI/ESD environments can result in damage to the sensor electronics.

Root Cause Analysis (RCA) Tips
RCA DEFINITION
One of the many problems with the use of the term RCA is that it has no standard, accepted definition. Even the major RCA providers on the market today cannot agree on a definition of RCA nor its essential elements. This is primarily because it is blocked by business concerns that if such definitions and elements are standardized, and my product or approach does not meet the requirements, I will be at a business loss {that is another article!).
My point here is that for proper communication within your own organization, you should develop a definition of what RCA is for your purposes. That way everyone can be on the same song sheet when it comes to RCA. Without such a definition, everyone interprets it to be what they want it to be and there is a breakdown in communication.
Below is a definition provided on a listserve I participate on, that we find acceptable:
Root Cause Analysis is any evidence-driven process that, at a minimum, uncovers underlying truths about past adverse events, thereby exposing opportunities for making lasting improvements. (5/20/04 – Mr. William Salot)
Use this as a draft to form your own definition, but whatever you do, define what RCA is for your organization.
