4.5 Overload protection (OVERLD)
4.5.1 Function
The ESM303 protects a load cell or force gauge from overload by measuring incoming analog voltage
and stopping crosshead travel when the programmed percentage of full scale has been reached. The
default setting is for Mark-10 instruments (±1V full scale), however, the setting may be changed to ±2V or
±4V to accommodate other instruments.
Default setting: OFF
Available settings: MARK-10, OTHER 2V, OTHER 4V, OFF

4.5.2 Compression and tension overload settings (COMP OVERLD and TEN OVERLD)
This setting corresponds to the percentage of full scale at which crosshead travel stops. For example, a
setting of 80% for a 100 lbF capacity force gauge would stop crosshead travel when approximately 80 lbF
is reached.
Note:
Overload protection is active only for forces applied in the same direction of travel.
Default setting: 100%
Available settings: 20% - 120% (10% increments)
