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 schematic and the hookup diagram in Adobe Acrobat format.
