AFG Control Test
With an additional cable (351-092), a Mecmesin AFG digital force gauge can be used to
set load limits to control crosshead movement.
Load setpoint, action (reverse/stop) are all set on the gauge under the ‘STAND’ menu.
Here you can select the action when the limit is reached; ‘REVERSE’ or ‘STOP’ and the
type of control limit ‘BREAK’ or ‘LIMIT’.
