Basic Force Gauge User’s Manual
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.
To power up the gauge press the
ON/OFF
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
zeroes. This is because the gauge re-zeroes itself
during the self test routine. See note at left.
If a force is applied perpendicularly via the sensor
probe (hole at bottom of BFG), the reading on the
display will register the applied force.
Forces greater than 120% of full-scale will produce an
audible beep until load is released and an
OL
symbol
will appear on the display
for 30 seconds
.
Forces greater than 150% of full-scale will produce an
audible beep until load is released and an
OL
symbol
will appear
permanently
on the display. Consult your
Quantrol distributor to arrange repair.
To power down the BFG press the
ON/OFF
key.
When tensile forces are applied, the tension symbol
shown in Figure 2 is displayed.

When compression forces are applied, the compres-
sion symbol shown below is displayed.
A load indicator bar alerts the operator to how much
load has been applied to the transducer. As the load
approaches the maximum rating of the transducer, the
indicator bar changes appearance when above
approximately 80% of the rated capacity. This warns
you that steps should be taken to prevent overloading
Do not overload
the
transducer, as this will
cause irreparable
damage.

If the BFG has
suffered a serious
overload condition, the
load indicator bar will
be partially displayed
even when no load is
present. This is a
warning that the load
cell is damaged and
you should immedi-
ately contact your
Quantrol distributor to
arrange repair.
The load indicator bar
is independent of the
zero function and thus
provides good visual
reference of potential
overload conditions.
