          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.
