Parameter
Note: DC output is performed by the Base parameter.
*1: Accuracy is specified at leading edge - trailing edge = 1µs
For example, accuracy specifications are
given as ±% of set/measured value (0.1%)
plus offset value (30pA+200fA×Vout) for the
100nA range. The offset value consists of a
fixed part determined by the set/measuremet
range and a proportional part that is
multiplied by Vout.
