– 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.
