Probing Principles
Ampere-Second Product is the maximum
width of pulsed current that you can
measure when the pulse amplitude is
between the maximum continuous and
maximum pulsed current speci
fi
cations.
The maximum continuous speci
fi
cation
varies by frequency.
To determine if your measurement exceeds
the Ampere-second product, you must
fi
rst
determine the maximum allowable pulse width
or maximum allowable pulse amplitude, as
described in the following section.
NOTE.
Always degauss the probe after measuring a current that exceeds the maximum continuous current, maximum pulsed
current, or Ampere-second product rating of the probe. Exceeding these ratings can magnetize the probe and cause measurement
errors.
