Describes accuracy of the 4mA low-scale offset current. Does not include input amplifier effects. Can be trimmed to zero.
Voltage measured with respect to I
RET
pin.
Does not include initial error or TCR of gain-setting resistor, R
G
.
Increasing the full-scale input range improves nonlinearity.
Does not include Zero Output initial error.
