EN_1 digital display meter (EN_2)Detailed product description：

The WY2851D digital Q meter (50MHz) is a high-frequency impedance measurement instrument based on the principle of series resonance, which measures the high-frequency effective inductance, Q value, capacitance value, and ∑, tg δ of inductors, capacitors, insulation materials, etc The WY2851D digital Q meter has been digitized on the basis of the original WY2851Q meter, and the mechanical structure has been improved in terms of long service life.

Features:
*Our company's innovative automatic Q-value reading technology greatly improves the accuracy and speed of Q-measurement
*As low as 20nH residual inductance, ensuring minimal error in directly reading Q values at high frequencies
*Specially designed LCD screen with menu style display of multiple parameters, Q value, test frequency, tuning status, etc
*Q-value range automatic/manual range control
*Digital Q-value presetting can improve the reliability and speed of batch testing
*The VCO adjusts the test frequency, and its smooth continuous frequency variation enables convenient measurement of Q value for Δ f.
