LCFM-1 - PORTABLE METER INDUCTION, CAPACITY AND FREQUENCY - PLATE PCB

Producer: AVT

When dealing with radio systems, we often face the problem of measuring small capacitances, inductance or frequency of radio signals. LC bridges and frequency meters are best suited for this type of tasks. However, these devices do not belong to the cheapest ones, so the novice electronics usually only has a universal multimeter at its disposal. Most popular multimeters allow you to measure capacitance and frequency, but not inductance. In addition, the measurement of capacitors of 1 nF or less is subject to a significant error, while the maximum frequency usually does not exceed several hundred kHz. Due to the lack of an inexpensive measuring device that allows measurements of these values, the idea of making an appropriate measure on its own was born.

Recommendations: the instrument will without doubt be useful in the workshop of every constructor's electronics.

Basic information:

  • capacity measurement with 0.1pF resolution in the range of 0.5 pF.0.1 mF (± 3%)
  • inductance measurement with a resolution of 10 nH in the range of 10 nH.10 mH (± 3%)
  • frequency measurement in two measuring ranges with an accuracy of ± 30 ppm:
    • 50 Hz.12 MHz with a resolution of 4 Hz
    • 1 kHz.250 MHz with a resolution of 64 Hz
  • input sensitivity: 20 mV rms.
  • input impedance: 2 kV.180 V (ends of ranges).
  • LCD display: 2ž16 characters.
  • Power: 3 V (2 AAA batteries).
  • dimensions: 118 mmž74 mmž29 mm.
  • automatic power off, if the meter is not used for 5 minutes.
  • a printed circuit board and documentation in the set
