INPUT: Range 10E3-10E11 V/A 1pA=100mV output Voltage Burden:＜200μV（18C-28C）for inputs＜100μA ＜10mV for inputs ≥ 100μA 20μV/C temperature coefficient. Maximum Overload:100V on 10E4 to 10E11 V/A ranges;10V on 10E3V/A range. Higher voltage sources must be current limited at 10mA. Current Suppression +-5nA-+-5mA OUTPUT: Range:±10V,1mA;bias voltage off. Impedance:<100Ω DC-175kHz.
LOW PASS FILTER: Ranges:10μs to 300ms（+-25%）in 1,3,10sequence or OFF. Attenuation:12dB/octave.
