4.5 Upper and Lower Travel Limits (UPPER LM and LOWER LM)
This setting corresponds to the travel distance the crosshead moves before stopping or cycling. Upper
and lower limits are programmed individually. The programmed distances are relative to the zero position
of the crosshead. The travel indicator can be zeroed by pressing and holding STOP for 3 seconds.
Default settings: +12.000 in, -12.000 in
Available settings: From -19.000 to +19.000 in
Label Description
+
Increases the travel limit setting by .001 in or .02 mm.
Holding down + will increment at an increasingly faster rate.
–
Decreases the travel limit setting by .001 in or .02 mm.
Holding down – will increment at an increasingly faster rate.

4.6.1 Overload Protection (OVERLD)
The ESM301 protects a force gauge from overload by measuring incoming analog voltage and stopping
crosshead travel when the programmed percentage of full scale has been reached (see Section 4.7). The
default setting is for Mark-10 gauges (±1V), however, the setting may be changed to ±2V or ±4V to
accommodate other force gauges.
Default setting: OFF
Available settings: MARK-10, OTHER 2V, OTHER 4V, OFF
4.6.2 Compression and Tension Overload Settings (COMP OVERLD and TEN OVERLD)
This setting corresponds to the percentage of force gauge full scale at which crosshead travel stops. For
example, a setting of 80% for a 50 lbF capacity force gauge would stop crosshead travel when
approximately 40 lbF is reached.
Note:
When the crosshead is moving in the UP direction, only the tension overload setting applies. When
the crosshead is moving in the DOWN direction, only the compression overload setting applies.
Default setting: 100%
Available settings: 20% - 100% (10% increments)
