FAQs

Quantum-II

How will I know if my RJL analyzer is operating correctly (calibrated)?

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.

Is there any chance of electrical shock while operating the RJL analyzers?

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.

Will climate affect the BIA test?

Yes, but only when climate changes are extreme.

Is the RJL equipment FDA approved?

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.)

What is the life expectancy of an RJL analyzer?

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.

Are the RJL analyzers very difficult to operate?

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.

How do I know when the Quantum-II or Quantum-X needs a new battery?

A line of decimal points will appear at the bottom of the LCD screen.

What is the difference between the Quantum II analyzer and the Quantum X?

The difference between the two units is the resolution. The Quantum II has a resolution to 1.0 Ohms and the Quantum X has a resolution to 0.1 Ohms., or ten times that of the Quantum II.

Both the Quantum II and the Quantum X are hand held analyzers that weigh 11 oz., and run on a 9-volt battery (ONLY).

Neither system stores data nor do they have serial communication capability.

All RJL BIA instruments test with equally accurate resistance and reactance results, and all RJL BIA results can be entered into our current software for body composition analysis.
