Q: How to Capture the I_Coil Waveform Using the GRL-C3-MP-TPR Tester?
A:
The AC current measurement fixture by GRL can be used to measure the actual coil current as shown in the image below.
Below is a sample screenshot of the I_Coil capture which displays the voltage, not current in amps, if you probe the I_Coil.
For example:
Ipp = Vpp/(10*.02)
10 is the amplifier gain
0.02 is the series resistor value
