Procedure B: Maximum
Allowable Pulse Amplitude
To determine the maximum allowable pulse amplitude do the following:
1.
Measure the pulse width at the 50% points.
2.
Divide the Ampere-second (or Ampere-microsecond) speci
fi
cation for the
range setting of the probe by the pulse width. The quotient is the maximum
allowable pulse amplitude; the peak amplitude of the measured pulse must
be less than this value.
For example, the TCP312 Current Probe has a maximum Ampere-second
product of 500 Arms in the 10 A/V range setting. If a pulse measured with
a TCP312 probe has a width of 15
μ
s, the maximum allowable peak current
would be 500 Arms divided by 15
μ
s, or 33.3 A.
