Introduction
BFG Power
Supply
When alkaline
batteries are fitted, the
AC adaptor/charger
must NEVER be
connected to the BFG
due to risk of acid
leakage which could
damage the instru-
ment.
The QuantrolTM Basic Force Gauge (BFG) can
measure tensile and compressive forces accurately
while still being easy to operate.
Please check the unit for any physical damage. If any
damage is found, please notify your authorized
Quantrol dealer.
The most commonly used features of the BFG are
accessed with a single key press on the instrument:
• displaying force
• peak hold
• zero
• changing units of measure
Other features can be accessed easily by pressing
and holding different 2 key combinations.
The BFG comes with five Nickel Metal Hydride AAA
rechargeable batteries. For safety reasons the
batteries are shipped discharged. To obtain maximum
battery life we recommend that you charge them with
the charger/adaptor supplied for at least 14 - 16 hours
when you first receive the BFG.
To insert the batteries you must first remove the
battery cover on the rear of the gauge by unscrewing
the two retaining screws. Fit the batteries in the
battery holder. Be sure to match the marked polarity.
Refit the battery cover and tighten the screws.
Connect the AC adaptor/charger to the BFG charger
socket and charge the batteries for 14 - 16 hours.
Only use the adaptor/charger supplied.
The BFG can also be powered directly from the AC
adaptor. You can do this with or without the recharge-
able batteries installed. Connect the AC adaptor/
charger to the BFG and a properly grounded outlet of
the correct voltage. Only use the adaptor/charger
supplied.
If the rechargeable batteries are installed, a trickle
charge will continue during AC use of the unit.
The BFG can also be powered by AAA 1.5V alkaline
batteries (not supplied). Follow the same instructions
as above, except for use of the charger. See warning
at left.

Mounting to a
test stand
Powering up
Affix either the short extension rod (30mm long) or the
long extension rod (130mm long) to the load cell
probe in the hole at the bottom of the gauge by
tightening it gently with the fingers.
Your chosen grip or accessory may now be connected
to the extension rod.
When fitting a grip ensure that it is screwed finger-
tight only. Excessive torque can damage the load
cell.
On the rear of the gauge there are two M5 threaded
holes, which can be used for mounting the gauge to a
Quantrol test stand.
Each Quantrol test stand is supplied with a dedicated
‘dovetailed mounting bracket’ and screws for this
purpose.
If you wish to mount the gauge to another type of
stand, ensure that the screws used are threaded into
the gauge to a maximum depth of .21 inch (5.5mm).
The final thread is peaned but if screws are fitted
beyond this depth, damage to the load cell will occur.
As shown in Figure 1 the control panel has 6 keys.

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.
Figure 2
Tension symbol
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.
Display of
Tension/
Compression
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.

Zeroing the
Gauge
Any load applied prior
to zeroing must be
considered as part of
the full-scale capacity.
Changing the unit
of measurement
Max (Peak)
Readings

the transducer.
For tensile forces the indicator bar is solid then
dotted. For compressive forces the indicator bar is
dotted then solid. See Figures 3b & 3c
During the operation of the gauge it is often necessary
to zero the display – e.g. when you wish to tare out
the weight of a grip, so it does not become part of the
measured reading. Press and release the ZERO key.
The display will blink momentarily as the zero opera-
tion is carried out.
You can choose from the following units of measure-
ment depending on the capacity of your gauge:
milliNewtons, Newtons, gram-force, kilogram-force,
ounce-force or pound-force.
To change the display units press and release the
UNITS key. Each successive key press will select the
next available unit of measure until the gauge returns
to its original setting. The BFG automatically converts
readings as new units of measure are selected.
The gauge detects and stores maximum (peak) force
in both compressive and tensile directions.
Press the MAX key. The display will show the word
MAX together with the highest tensile force and the
highest compressive force detected during the test.
The current load being applied to the transducer is
also displayed.

Press the MAX key again and the word MAX disap-
pears from the display. The display indicates forces
applied in both directions as they are applied to the
transducer and maintains a running display.
