5 OPERATING MODES
5.1 Mode Overview
The ESM301 can be operated in several modes, including combinations of these modes:
1. Basic Mode
Manual control of crosshead motion.
2. Auto Return Mode
Crosshead moves to a limit switch or force set point, travel distance, preload, or sample
break (referred to as soft limits), whichever occurs first. Then, it reverses and moves at
maximum speed to the other limit, whichever occurs first.
3. Cycling Mode
Crosshead cycles between limits at the selected speed(s), and pauses at each limit or set
point for a selected period of time.
4. Preload Mode
Crosshead moves until the preload has been reached, and performs the action programmed
in the setting. An auto-return, cycle/dwell time, or break detection sequence may follow.
5. Load Holding Mode
Crosshead moves to a force set point, stops, then dynamically adjusts position to maintain
the programmed force. An auto-return or cycle/dwell time sequence may follow.
6. Break Detection
Crosshead stops when a sample break has been detected. An auto-return or cycle/dwell time
sequence may follow.
7. PC Mode
See Communications section.

The item selected will be capitalized, as shown in the figure above. The set speed can be changed in
Test Feature Setup. If enabled, the up and down speeds can be configured independently of each other
(UP SPEED and DN SPEED). Otherwise, the SPEED setting corresponds to crosshead speed in both
directions.
