Deformation and Load will remain live displays during the test. When deformation reaches the
target value, the test stops.
Testresultsareshownonthereportingscreen:
PEAK LOAD: XXX.X g
DEF@PEAK: XXX.X mm
WORK: XXXX.X mJ
FINAL LOAD: XXXX.X g
TEMP: XXX.X F
Figure III.27
Peak load is the maximum load measured during the test. Temperature at peak load is only shown
if temperature probe is used.
Def@Peak is the sample deformation at the peak load. The trigger position is the zero deformation
reference point.
Workistheareaundertheloadcurveandismeasuredinmillijoules.
Final load is the load at the target deformation.
NOTE:Itisnotpossibletoperformtensiontestswiththe100gloadcell.
TARGET HOLD-TO-LOAD – this test applies a constant force to the sample material for a
user-dened time interval.
Thetargetholdsetupscreenallowstheoperatortoassignfourvariables:HoldTime,TriggerLoad,
Target Load, and Run Speed.
TherstlineallowstheoperatortoinputaHoldTime.Thetimeisenteredaswholeseconds;the
HOLDTIMEeldlengthisfourdigitslong.TriggerforceandTargetLoadentriesconformtothe

Note that the information to the left of the screenshot details the instrument type, the maximum
allowable trigger value with its associated resolution, and the proposed target load maximums and
resolution.Alsolistedisthetargetedholdaccuracyof0.5%fullscale.
The target load value is in whole grams and corresponds to approximately 0.01 Newtons for most
load cells. However, the same resolution restrictions as used in Trigger Value entry will apply. For
example,with50000gloadcell,theleastsignicantdigitinNewtonmodewillbe0.05N.
Pressing the Select Knob, when the cursor is positioned over the HOLD (time) text, will start the
