So what is hot,
The following is not a definitive list of what is available, however, it is a list of what I have used and have proved capable to do the job, and what should be avoided.
If you agree, disagree, or simply have another comment to add then please do get in touch.
Fluke 123 Industrial Scopemeter (tba)
Full Disclosure Recorders
When it comes to purchasing gear, the route to follow is actually quite simple. If your main emphasis is tracing faults then one definitely requires the 'oscilloscope' type. They are quicker (but not easier) to use and are easily moved from one place to another. If it is the long term survey or investigation, or where the actual fault is to still be established, then the 'full disclosure' type is the only one to be considered.
The latter do not weigh in at a cheap price and this has made many buy the wrong type in the first place. When it comes to consultancy work, the 'full disclosure' can pay for itself in less than a year. Buying both types will increase performance three-fold meaning at least twice as much work (i.e. double income, at less than double the outlay!).
If you are not sure what to buy (especially if you are being pressurised by a salesman), then please write. I will gladly write to the company who wants you to buy from them. The test is simple - If they let me have a unit, this will go some way to proving their financial standing and can fund the technical support backing you may require. The second test is how it compares with the RPM-PR. Remember, we want to feature anything that credits PQ engineering.
