a. Accuracy: ± (% of reading or setting value + offset value). Vout is the output voltage in volts.
b. Iout is the output current in amps.
c. The accuracy is applicable when offset cancellation has been performed.
d.
The offset current specification is multiplied by one of the following factors depending upon the ambient
temperature and humidity. See
HRSMU Current Range, Resolution, and Accuracy
