Notice

(1) Under the power supply condition of ±12V≤VC≤±15V, the measurement range of the sensor will be reduced;

(2) If the customer uses the rated load resistance, the current to be measured needs to be limited to the rated current. If the full-scale current is to be measured, the load resistance should be smaller than the rated resistance .

(3) Linearity data does not include zero offset.
