Consult Welch Allyn if readings differ from those shown.
NOTE: Ohmmeters will not indicate a change in resistance of the load cell transducer when weights are applied to scale. This
is due to the extremely small change in resistance of the strain gauges employed (<1 ohm) and the fact that the bridge
configuration presents a constant value of resistance when measured from its terminals.
