1 Specifications under standard operating conditions but at an ambient temperature of 23°C±1°C and excitation current of 1 mA.
2 Specifications under standard operating conditions. If the ambient temperature is between 5°C to 20°C or 26°C to 40°C, add
the temperature coefficient compensation to the accuracy. When excitation current Is[mA] is between 0.1 mA and 1 mA, add
