Application Examples
Inductance Measurements
You can use the current probe to measure the inductance of coils that have either a low-impedance or high-impedance pulse
source of a known value.
Low-Impedance Pulse Sources
This fi gure shows a constant-voltage pulse
generator of extremely low output impedance
connected to an inductor that has low
resistance.
1. Connect the inductor across the output
terminals of the pulse generator.
2.
Maintain a constant voltage across the
inductor.
3. Clamp the current probe over one of the
source leads.
NOTE.
If the probe impedance is a signi fi cant
part of the total circuit inductance, measurement
accuracy will be affected. Refer to the probe
speci
fi cations for probe insertion impedance.
