Note 1: 1000 Ohm load cell – Typically 0.53V for 350 Ohm cell
Note 2: Set by calibration resistor
Note 3: Limited by the 300Ω barrier impedance
Note 4: 1000 Ohms load cell – change R1 to suit other load cell impedances.
Note: Recommended bridge impedance is 1,000 Ohms
Note: The voltage between either of the power supply connections and the load cell shield should not exceed 50V.
Any leakage will be greater than 10M Ohms.
