Maximum Allowable Puls e Amplitude
To de termine 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) specification
for the range setting of the TCP0150 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 TCP0150 probe has
a maximum Ampe re-secon d product of
15000 A-μs in the 150 A range setting. If a
pulse measured with the probe has a width of
40 μs, the maximum allowable peak current
would be 1500 0 A-μs divided by 40 μs, or
375 A.
