"Can Buy It Now in my ebay store" Model No.: RVT322 Brand: REK RVT322 RVT322 DOUBLE CHANNEL AC MILLI-VOLTAGE METER General description Double channel input terminals, The scope of the operation frequency is 10Hz?1M Hz,the scope of voltage is 300?V?100V,It can be seted according to the difference switch and process the input signal separately or synchonously,It can eliminate the outer signal inductance 0n the status of low frequency because of the BNC terminals input.It can be used as a voltage lever meter with decibel scale(0dB,AC 1V square root value)and milli-watt scale( The output terminals is connected with oscillator to observe the waveform or used as preamplifier Basic charateristics The test frequency range :10Hz?1M Hz, The ACV test range:300?V?100V Milli-volt,decibel,milli-watt triplex read scale Hi reliability and stability. Electronical characteristics Volatage range:12 separate test range from 300?V?100 V Decible range: 12 separate test range from -70 dB?40 dB Precision : 1kHz benchmark?3% Input impedance: 10 separate range all have 10 M? impedance, The input capacitance?40uF Frequency bandwidth response: ?3% 20 Hz?200 kHz ?5% 10 Hz?500 kHz ?10% 10 Hz?1 MHz Noise: noise?s scale warp within 2% in the state of input terminals? short,The maximum of the input voltage ( DCV+the peak of ACV ) 300 V( 300 ?V?1 V Range) 500 V( 3 V?100 V Range) Amplifier output: 0.1 V(Sqare value) ?10% ,Without load. Current and power: 220 V( 50 / 60 ), Approximate 6W. |
