Probing Principles
Increasing Sensitivity
If you are measuring DC or low-frequency
AC signals of very small amplitudes, you can
increase measurement sensitivity of your
current probe by doing the following:
1.
Wind several turns of the conductor under
test around the probe as shown. The
signal is multiplied by the number of turns
around the probe.
2.
To obtain the actual current value, divide
the displayed amplitude by the number of
turns.
For example, if a conductor is wrapped
around the probe
fi
ve times and the
oscilloscope shows a reading of 5 mA DC,
the actual current
fl
ow is 5 mA divided by
5, or 1 mA DC.
NOTE.
Winding more turns around the probe increases the insertion impedance and reduces the upper bandwidth limit of the probe.
