*1: The accuracy is applicable when offset
cancellation has been performed.
*2: The offset current specification is
multiplied by one of the following factors
depending upon the ambient temperature
and humidity (RH = Relative Humidity):
Vout is the output voltage in volts.
Iout is the output current in amps.
For example, accuracy specifications are
of set/measured value (0.04%)
plus offset value (200nA+1nA
1mA range. The offset value consists of a
fixed part determined by the set/measuremet
range and a proportional part that is
multiplied by Vout or Vout/100.
For example, accuracy specifications are
of set/measured value (0.02%)
plus offset value (1mV+13
range. The differential mode offset value
consists of a fixed part determined by the
measurement range and a proportional part
