Explanation of the front panel from left to right:
• On/Off Indicator (red): Lights up when power to the instrument is on.
• Head Up: Used to raise the instrument head.
• Head Down: Used to lower the instrument head.
• Stop: Terminates whatever operation the instrument is performing, for example finding the gap zero,
mapping the bearing or running an experimental procedure.
• Start: Used to start an experimental procedure. (AR-G2 only)
• Bearing Lock: Applies a software lock to bearing to prevent the instruments shaft from rotating. This
lock will be over-ridden when the experimental procedure is started. (AR-G2 only)
• Zero Gap: Starts the automatic gap zero position finder.
• Release: Used as the Smart Swap release button.
• Smart Swap indicator light (green).
Smart Swap™
The AR rheometers’ feature “Smart Swap” technology that automatically senses the temperature control
system present and configures the rheometer operating software accordingly, loading all relevant calibra-
tion data. The use of this feature is covered in this manual.
Also available for use with the AR-G2 only are the Smart Swap™ geometries, which are an extension of
the Smart Swap technology. These geometries can be automatically identified when installed on the AR-
G2 rheometer. The magnetic coating on the head of each geometry provides the read/write technology that
will uniquely identify it to the instrument.
Auto GapSet Mechanism
The auto GapSet facility has three major functions, as follows:
• Automatic setting of gaps via software
• Programmed gap closure
• Thermal gap compensation
These features of the GapSet mechanism are described in detail in the TRIOS Software Online Help.
