Re: [TCML] LC Meter

[Ed Phillips <evp@xxxxxxxxxxx>]

If this question is for me you disconnect primary capacitor and inductor 
from each other and circuit [hoping I'm not getting too simple] and 
connect to the LC input terminal.  Same with secondary except nothing to 
disconnect.  Before reading inductance leads at inductor end and zero.  
For capacitance open leads at capacitor end and zero.  Does this answer 
you OK?  Note that this sort of instrument doesn't make measurements at 
fixed frequencies so results might not agree exactly with measurements 
made with a standard LCR bridge excited by a 1 kHz signal or readings 
taken with a Q meter at whatever frequency is appropriate for the 
inductor being measured.  However, 'good enough for government work' - 
this isn't a precision instrument but very convenient.  In order of 
decreasing accuracy LCR bridge [gives LOW FREQUENCY inductance], Q 
meter, and finally LC meter.  Since you'll be tuning your coil anyway to 
adjust for effects of actual streamer capacitance on 'maximum good' it 
doesn't really matter at all and the convenience is hard to beat.
