Basic Force Gauge User’s Manual
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 Quantrol
TM
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.
