2/11/2010 - LC Meter kit has sold out
The LC Meter is a Morse code inductance / capacitance meter kit.
It offers:measures capacitance with a 1 pF resolution
measures inductance with a .01 uH resolution
code speed can be varied from 5 to 35 wpm in ARRL steps
use with supply / battery from 7 to 15 volts
16 selectable sidetone frequencies
all board mounted parts included, just add a piezo speaker, power connector
and test (alligator) clips to complete the kit
capacitor measurement range: 1 pF to roughly 1 uF
(measuring electrolytic and other polarized caps isn't recommended)
inductor measurement range: .01 uH to roughly 10 mH
accuracy: probably worse than the +/- 1 percent calibration capacitor
note: some builders have reported that inductance readings seem too low (6 percent). I've seen inductance readings
about 2.5 percent low as compared to other LC meters.
For more details, please download the LC Meter manual, the
and the hookup diagram
in Adobe Acrobat format.
