AH500 Module Manual temperature sensor, O n + and I n + have to be short-circuited, and O n - and I n - have to be short-circuited. ( n is in the range of 0 to 7.) *2. If users want to measure the resistance in the range of 0 Ω to 300 Ω, they can use a two-wire or three-wire sensor instead of a four-wire sensor. *3. User need to select an appropriate sensor. If a Ni100 temperature sensor, a Pt100 sensor, and a resistance sensor are used, the internal excitation current is 471.5 μA. If a Ni1000 temperature sensor, and a Pt1000 temperature sensor are used, the internal excitation current is 204.8 μA.
