key. A short self test runs during which the display will show the model and capacity in newtons.

After the self test, providing no load has been applied  to the instrument, the display will show all zero’s.  This is
because the gauge re-zero’s itself during the self test routine.

Please note that a BFG measuring very low forces may not show zero if it is moved during the self test

routine. Once it is properly mounted and zeroed the reading will be stable.

If a force is applied perpendicularly via the extension rod to the loadcell, the reading on the display will register
the applied force.

Should the instrument have sustained a catastrophic overload, the symbol ‘OL’ will be permanently displayed and
the instrument must be returned to Mecmesin or an approved Mecmesin distributor for repair.

Forces greater than 120% of full-scale will produce an OL symbol which will remain on the display all the time the
overload is present.
