A 500-ohm resistor is included with all the RJL analyzers. This resistor allows you to check the calibration of the analyzer. For an explanation on how to test the calibration of your unit, please refer to the manual.
No, all of the RJL analyzers are designed with isolation transformers that prevent any harmful current from being exposed to the subject while being tested.
Yes, but only when climate changes are extreme.
The Food and Drug Administration regulates all BIA devices as class II medical devices. Manufacturers must receive clearance from the FDA to market a class II device. Please visit the FDA website for more information on RJL registration and clearances. ( FDA Website – search for RJL Systems under Applicant Name or Owner Name.)
So long as you take care of your analyzer, it can last a long time. RJL has many of their customers (from as far back as 1980) using their originally purchased analyzers.
No, anyone can operate the RJL analyzers. It is helpful, however, to read the supplied manuals first.
In addition, anyone planning on using an analyzer in a clinical setting should practice applying the electrodes and collecting the resistance and reactance values to ensure that they are able to reliably and repeatably place the electrodes in the same spots on the skin every time.
