– the displayed value is greater than the upper
force limit (NO GO HIGH)
– the displayed value is between the limits (GO)
– the displayed value is less than the lower force
limit (NO GO LOW)
Note: Set point indicators and outputs reference the displayed reading, not necessarily the current live
load.

6.4 Using Set Points to Control a Mark-10 ESM301 Motorized Test Stand
When using set points to stop/cycle crosshead motion on an ESM301 stand, the upper set point must
always be a value in the tension direction, and the lower set point must always be a value in the
compression direction. Both set points must be set, even if the intended application is to stop/cycle at
only one of the set points. The opposite set point should be a value sufficiently large that it does not get
triggered during the course of the test.
For certain other Mark-10 test stands, the tension and compression directions are reversed.
7 BREAK DETECTION
The break detection function identifies when a sample has broken, clicked, slipped, or otherwise reached
a peak force and then fell by a specified percentage drop. Upon detection of the break, the gauge can
perform several automatic functions, depending on the mode in which break detection is enabled, as
follows:
1. Transmit the peak reading (Auto Output).
2. Save the peak value to memory (Auto Storage).
3. Zero the primary and peak readings (Auto Zero).
4. Toggle a pin (for example, to stop crosshead movement on a Mark-10 motorized test stand).
Break detection functions and settings are configured from a central location, and apply to any mode in
which it is enabled. Refer to the Operating Modes section for details on configuring each mode.
