FORCE GAUGES,
LOADCELLS &
FIXTURING
Note: Loadcells and force gauges
are delicate pieces of equipment
and can easily be damaged
irreparably.
COMMUNICATION
WITH EXTERNAL
DEVICES
Note: The external cable must not
exceed 3 metres in length.
You will need to attach a force measuring device to your
MultiTest 1; this will usually be an Advanced Force Gauge
(AFG), Basic Force Gauge BFG) or an S-beam loadcell. Attach
an AFG or BFG by screwing a dovetail bracket to the back of
the gauge, slide it (with the loadcell stud pointing downwards)
onto the moving crosshead dovetail (C, in fig. 1), and then
tighten with the Allen key provided. Attach an S-beam loadcell
by screwing it into a tensionblock module, then proceed as for
attaching a gauge. If you have purchased special fixturing,
attach this to the gauge/loadcell and/or your MultiTest 1.
One way of causing irreparable damage would be to drive the
test frame downwards until the loadcell (or loadcell stud on
AFG & BFG instruments) hits something ‘solid’. This is a risk
when a user is not yet familiar with operating a new test frame.
Consequently it is essential to set the limit switches (B, in fig. 1),
so that upwards/downward travel of the crosshead is limited
to prevent over travel and drive the gauge into the grips, stand
or apply excessive load to the sample. Adjust the limit switches
(B, in fig. 1) according to your sample dimensions and testing
requirements.
There is an external control port at the rear of the MultiTest 1.
The Display Unit Interface (b,in fig.2) enables the MultiTest 1 to
respond, via the appropriate Mecmesin cable, to signals from
an AFG. For further information please refer to the AFG
Operating Instructions.

The MultiTest 1 must be
powered off when
attaching or disconnecting
the cable. When the
display unit interface is
not in use please ensure
that it is covered with the
supplied shield at all
times.
