	Noise Meter 2ch Input Freq Range:10Hz~500KHz,without weighing filters Voltmeter Range:10μV to 300V,full scale, 16ranges in 1,3,10 sequence; -100dB to +50dB,full scale(0dB=1Vrms)and -98 to +52dBm,full scale (0 dBm = 0.775 Vrms). Accuracy : a) At AVERage reading : ±3 % of full scale, except 10 uV range. b) At QUASI-PEAK and R.M.S reading : ±5 % of full scale,except 10 uV and 30 uV ranges. (Note : Not applicable at above 100V or 42 dBm,or when using a weighting filter.) Adjustable Sensitivity Range : 0 to more than -10 dB. Input Impedance : 1MΩ,approx.30pF in shunt : unbalanced. Maximum Input Voltage : AC : 10Vrms, DC : 450V,in 10uV to 30mV/range. AC : 330Vrms, DC : + AC peak,above 100mV range. *Output Voltage : At meter full scale and at open circuit : AC:1Vrms ±10 % DC:1V ±10 %
