Universal Bridge QS-18A

Universal Bridge Model: QS-18A Instrument: Applications: QS-18A Universal bridge is a lightweight portable multimeter bridge, can quickly capacitance, inductance, resistance element brief technical indicators to measure basic error. (according to the maximum count range) capacitor (CX) 0.5PF-100PF ± 2% ± (0.3PF), 100PF-100mF ± 1%, 100mF-1100mF ± 2% inductance (LX) 0.2uH-10mH ± 2% ± ( 0.3uH) 10mH-10H ± 1%, 10H-110H ± 2%, resistance (RX) 10mΩ-1Ω ± 2% ± (10mΩ) 1Ω-1MΩ ± 1% 1MΩ-10MΩ ± 2% residual impedance bridge: Capacitor about 2PF, inductance of about 0.1mH, resistance measurement range of about 1mW loss: Q value from the 0-1.1Q = 1 / DD value from 0-0.1,0-11 electrical internal bridge oscillator: Frequency: 1KC ± 10% output power:> 10mw consuming circuit; about 5mA bridge internal amplifier: magnification> 1500 noise about 100mv Current consumption: about 5mA this bridge internal oscillator and amplifier are common means another 2 6 9V flat battery as the power supply, the normal power supply, During normal operation of the total operating current of about 10mA, when measuring DC resistance bridge powered by the 150 ohms and 9V batteries in series protection resistors supplied by the meter refers to the zero bridge balance.
