✻ Specification same as XTR105P and XTR105U.

NOTES: (1) Describes accuracy of the 4mA low-scale offset current. Does not include input amplifier effects. Can be trimmed to zero.

(2) Voltage measured with respect to I

(3) Does not include initial error or TCR of gain-setting resistor, R

(4) Increasing the full-scale input range improves nonlinearity.

(5) Does not include Zero Output initial error.

(6) Current source output voltage with respect to I
