WY2851D Digitel Q Meter

Q Meter is a high-frequency resistance measurement instrument functioned by series resonance principle, applying to test inductors, capacitors, insulators with high-frequency for their effective inductance, Q, capacitance as well as ∑,tgδvalues.
WY2851D digital Q meter has been digitally intelligentized based on the old Q meter’s structure which has improved the security of the tuning mechanical structures.


  • Automatically Q value reading capability which enhances the accuracy and speed of measuring。
  • The residual inductance is below 20nH, guaranteeing a small deviation occurred during reading the Q value at high frequency.
  • Special LCD screen menu form is able to display several parameters: Q value,test frequency, tuning state, etc.
  • Q value range could be automatically or manually controlled.
  • Digital Q value preset which improves the reliability and speed of the batch test.
  • VCO adjustable test frequency, possessing a smooth and continuous frequency change, facilitates Q value measuring with △f method.
