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-defined time interval.
The target hold setup screen allows the operator to assign four variables: Hold Time, Trigger Load,
Target Load, and Run Speed.
The first line allows the operator to input a Hold Time. The time is entered as whole seconds; the
HOLD TIME field length is four digits long. Trigger force and Target Load entries conform to the
load cell type of the instrument as shown in Figure III.28:
TEST:TRGT HLD: ____ s
TRIGGER: _.___ N
TARGET LOAD: __.__ N
SPEED: 10.0 mm/s
4500 gram(44.127N)
500g trigger max(4.905N), 0.5 increments(0.005N)
4500g load max(44.2N), 1g increments(0.01N)
TEST:TRGT HLD: ____ s
TRIGGER: _.___ g
TARGET LOAD: __.__ g
SPEED: 10.0 mm/s
Figure III.28
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 significant 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
Hold Time data entry. The cursor will be repositioned over the left most digit of the time field, which
