Fitting and Connecting an AFG 

The MultiTest

-dV 

has a dovetail bracket attached to the moving crosshead; this is used 

to mount AFG devices.  

To fit an AFG first, attach the AFG mounting bracket (part no. 432-427) to the back of a 

Mecmesin AFG or AFTI digital force gauge. Then slide the gauge sideways onto the 

dovetail and secure it by tightening the dovetail screw with an Allen key.  

To prevent damage, do not over-tighten the grub screw in the dovetail when a gauge 
bracket is not present. 

 

 

 

 

 

 

 

 

 

 

Note: 

Take care when handling lower capacity AFGs, as damage can easily occur from 

mishandling.  

It  is also essential to  ensure that the attached grips and fixtures do  not  overload the 

gauge. If in doubt, please check the weight of any addition grips and fixtures before 

fitting these.
