• Notes
• The RCA WV-510A Master VoltOhmyst is a high-quality, solid-state electronic voltmeter especially designed for stable, drift-free operation. It measures DC voltage from 0.01 to 1,500 volts, direct current from 0.01 milliamperes to 1.50 amperes, AC RMS voltage from 0.20 to 1,500 volts, AC peak-to-peak voltage of complex waveforms from 0.50 to 4,200 volts, and resistance from 0.20 ohms to 1,000 megohms.
  
  Seven overlapping ranges are provided for AC voltage, DC current, and resistance measurements, and eight ranges are provided for DC voltage measurement. Accuracy for all voltage and current functions is ±3% of full-scale reading.
  
  The solid-state measuring circuit features excellent stability and linearity, with minimum effect caused by temperature variations. Current drain is very low, assuring long battery life. Accuracy is maintained throughout the usable life of the batteries. A convenient battery test function is provided.
  
  An input resistance of 21 megohms on all DC ranges permits accurate test results on even the most critical low-impedance circuits.
  
  ACCESSORIES INCLUDE:
  (a) Model WG-301A Crystal Diode Probe. (Increases AC frequency range to 250 MHz);
  
  (b) Model WG-411A High Voltage Probe, less resistor. (Increases DC voltage range to 50,000 volts); and,
  
  (c) Model WG-436A Multiplier Resistor for WG-411A Probe.
