Use pliers to hold the bolt under the load cell and remove the nut. Don’t let the bolt fall through the
deck or you will need to unbolt the scale from the floor to retrieve it.
Loosen the setscrew holding the load cell. Remove the cell.
Check the new load cell. It should have “TOP” or a “T” written on it to show which side faces up when
installed. If not, install it so the serial number on the side is right side up. Reverse these steps to install
the new load cell.
After installing the nut, check to make sure the chain is not twisted. Straighten it if needed or the
weight readings will not track properly as gas is drained from the cylinder.
Recalibrate the side with the new load cell. This can be done before the lid is installed.
Troubleshooting:
If the weight goes negative when the tank is placed on the scale the load cell is upside down. It is
acceptable to reverse the positive and negative signal wires for that channel at the instrument or
terminal block instead of mechanically flipping the cell over. After fixing the problem remove the tank
and re-zero the instrument.
“AOL” or “-AOL” on the instrument means there is a wiring problem. Check the termial block for
loose or broken wires.
