TheCT3displaysthefollowinginformationwhiletheTargetHoldtestisbeingrun.:TIMEAT
TARGET, DEFORMATION, and the current measured LOAD. The sequence of events, and the
correspondingdisplayelds,isasfollows.
The display begins with the TIME at 0 while the probe descends at the selected PRE-SPEED (assigned
by the user in the GLOBAL PARAMETERS screen described elsewhere). Pressing and holding
the START button prior to reaching the TRIGGER load will override the PRE-SPEED setting for
theprobewithadefaultspeedof4.5mm/sec(knownasjogging).TheDISTANCEremainsat0.0
until the TRIGGER load value is reached when the probe makes contact with the sample. The
LOADeldthenstartstodisplaytheactualforcemeasuredbytheCT3.

When the measured LOAD reaches the assigned TRIGGER value, the probe speed is changed to
the assigned SPEED from the Target Hold setup screen. As the probe approaches the target load
atthepre-assignedspeed,therewillbeaxeddecelerationalgorithmthatreducesthespeedofthe
probe until it reaches the target load, based on a percentage of the load cell full scale. Therefore,
the pre-assigned probe speed only represents the maximum allowable speed. For example, if the
appliedload,whentheTRIGGERpointisreached,issufcientlyclosetothetargetholdload,then
