That wording is included for two reasons:

The analyzer is susceptible to external voltages. As little
as a few millivolts external voltage can make the analyzer
not read zero.

There also can be calibration problems. (For a period of
time every analyzer was actually calibrated incorrectly.)

Reactance should be zero at resonance but the meter might
not dip to zero fully.
