Measures currents in range of 10-11 to 10-15 amp by passing current through high-value precision resistor and amplifying voltage drop across resistor with direct-coupled amplifier of electrometer. British CV2348 is similar to CK5886. Bandwidth is 7.5 Mc. Zener diode D3 provides meter overload protection by damping at about 20% overload.-D.
