--- Quote from: woody on December 19, 2016, 06:55:21 pm ---It is nearly impossible without testing equipment, the easiest way is to connect the coil to a variable frequency source and connect a small resistor in series with one coil wire and vary the frequency with an oscilloscope across the resistor, when resonance is achieved the signal voltage across the resistor will rise. The higher you can get the frequency the better in most cases but other effects like ringing need to be observed. Another way is to buy an automatic LCR type meter and measure the inductance, these give a Q reading, the higher the Q the better in most cases.

Would this type of LCR meter be okay to use:

UT600 series RCL meter is a kind of 3.5-bithandheld digital meter with stable performance, safety, reliability, highaccuracy and manual range.
It can be used to measure the magnification times β of audion, diode forward voltage drop and circuit continuity.
UT 603 is applicable to testingresistance, capacitance and inductance of electronic laboratory, productionline, maintenance point and teaching.
It is the ideal tool of maintaining formany users.

You need the inductance to measure down into uh. Not mh.

Total overkill , but if its cheap...
