Note 1: 1000 ohm load cell – Typically 0.55 V for 350 ohm cell
Note 2: Set by calibration resistor. Load cells with less than 1 mV/V sensitivity are not recommended – drift and noise
performance will suffer.
Note 3: 24 V supply minimum – includes loop wiring resistance
Note 4: 1000 ohms load cell – change R
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 50 V.
Any leakage will be greater than 10 M ohms.
