minutes since the last key press or remote request or load change greater than 2% of full scale.
Holding down the ON/OFF key while the gauge ‘boots up’ will either enable or disable the auto-off function (i.e.
toggle from its current state). If the auto-off function is enabled then ‘Ao’ is displayed. If the auto-off function is
disabled then ‘No Ao’ is displayed. This setting is stored in the memory and is remembered when the gauge is
powered down.
Loadcell Diagnostic test
If you suspect that your loadcell transducer has sustained an overload it is possible to check the status of the
loadcell immediately.
Symptoms of overload may be (a) OL in display (b) probe not aligned perpendicularly to gauge (c) display will not
return to zero (d) F.S.D cannot be achieved (e) instrument readings are not repeatable.
An instrument showing an overload condition cannot be relied upon to provide accurate, repeatable

Place the gauge horizontally on a flat level surface without any accessories attached.
Hold down the
MAX
MAX
key whilst turning the gauge on. The value displayed is the percentage difference (Loadcell
offset) between the load currently present on the gauge and the gauges first ever calibration relative to full scale
counts.
For information:
For information:
If the % offset is between 5% - 10% it is advisable to contact your supplier to arrange a
recalibration of your BFG.
If the % offset is greater than 10% it is advisable to contact your supplier to arrange investigation and repair.
These values are given as an indicator only - the need for calibration/repair may vary according to the individual
characteristics of the loadcell.
Note: The % offset readings are for indication only and act as guidance and do not give an accurate indication

Removing the minus sign during data transmission
Press any key except the
ON/OFF
ON/OFF
key (which will turn the gauge off) to continue using the gauge.
Holding down the
TXD
TXD
key whilst turning the gauge on will enable or disable sending a minus sign with RS232
and Mitutoyo transmission. If the ‘transmit sign’ function is enabled then ‘2’ is displayed in the top row of the
display. This setting is stored in the memory and is remembered when the gauge is powered down.
Overload counters
If you suspect that the gauge has been subjected to overloading this can be verified by pressing the
UNITS
UNITS
key
whilst turning on the gauge this will display the number of overloads in tension first followed by the number in
compression. An overload is registered when the load exceeds 120% of the rated capacity.
Removing recorded overloads can only be undertaken by Mecmesin or an approved Mecmesin distributor.
Display messages
‘- OL -’
Overload - More than 120% of full scale load is
currently being applied to the transducer
‘OL’
Overload - The peak force reading was applied to the
loadcell in excess of 120% of full-scale
