Re: [TCML] Terry Filter Resistors

[Ed Phillips <evp@xxxxxxxxxxx>]

I also have a 27XT multimeter.  If I take a 1.0K Ohm, 1/2W carbon comp resistor (i.e. NO significant inductance) and try to measure its inductance with this meter, it reads 184mH.  I don't think so!

Bottom line - don't try to measure inductance of resistors with this meter!

	Measuring any kind of coil with this type of meter is sort of a gamble unless you know what you're doing - the measurement technique is quite an indirect one.  Works OK with reasonable coil Q but not at all suitable for measuring the inductance of a WW resistor.  To do that I'd break one and try to figure out the number of turns and then calculate it.  I don't think even a good impedance bridge would give useful results.
