Introduction
Operation
Thank you for choosing the Dillon Advanced Force
Gauge (AFG) or Advanced Force/Torque Indicator
(AFTI II) instrument. With correct use and regular
recalibration it will give many years of accurate and
reliable service.
The Dillon AFG is the latest in a series of highly
adaptable display units. By using the latest inte-
grated circuit technology it has been possible to
produce a truly universal display which can be used
to measure force, torque or weight when com-
bined with suitable transducers.
Upon receiving the unit please check for obvious
physical damage to the packaging material and the
instrument itself. If any damage is evident please
notify your Dillon distributor immediately.
We strongly recommend you keep all packaging for
future shipping requirements.
The most commonly used features such as force or
torque display, peak detection and the changing of
displayed units, can all be done with just one key
press per function on the front panel.
