Procedure B : Maximum
Allowable Pulse Amplitude
To determine th
e maximum allowable pulse amplitude do the following:
1. Measure the pulse width at the 50% points.
2. Divide the Ampere-second (or Ampere-microsecond) specification for the
range setting of the probe by the pulse width. The quotient is the maximum
allowable p
ulse amplitude; the peak amplitude of the measured pulse must
be less than this value.
For example
, the TCP312 Current Probe has a m aximum 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 μs, the maximum allowable peak current
would be 500 Arms divided by 15 μs, or 33.3 A.
