Calibration Error 3
Initial dead load overshoots to negative range. Check if the cell is loaded in
opposite direction, or +SIG and –SIG of the load cell are connected in reverse
order.
If Calibration Error 3 persists while load direction and cable connections are
correct, Zero calibration must be performed again after inserting a resistor
between +EXC and –SIG terminals of the load cell for shifting zero point. See
the table in the previous section “Calibration Error 2” for determining the
resistor to be inserted.
