*1 The voltage/current input is no less than 10%FS (FS indicates the full scope).
*2 Range of current readback value: (1/(1/R+(1/R)*0.2%+0.01),1/(1/R-(1/R)*0.2%-0.01)
a) When voltage input value is less than 10%FS: 0.2%+0.1/Vin (s);
b) When current input value is less than 10%FS, the load current precision is:
±(0.2%xVin/R3mA);
*3 Range of resistance readback value: ( 1/(1/R+(1/R)*0.2%+0.001),1/(1/R-(1/R)*0.2%-0.001)
