III.6 Operating Menu
The CT3 Texture Analyzer offers seven test modes, one calibration mode and one parameter
selection table.
Normal – single compression cycle.
Hold Time – compress and hold.
Cycle Count – compress sample several times.
Bloom – compression test measures gelatin bloom strength.
  TPA–twocycleTextureProleAnalysiscompressiontest.
Tension – pulls apart a sample using tensile force.
Hold to Load – applies constant force on a sample.
Static Load – monitors load while hanging weights for calibration.
Global Parameter – allows setting pretest speed, post test speed and temperature units.
Each test mode requires parameters to be set. All test mode selection and parameter setting is done
using the Select/Scroll knob (see Figure I.2). This knob is both rotated and depressed during operation.

These parameters, once set, will be maintained by the CT3 even after power down to facilitate
repetitive testing. The test mode used prior to powering down will be presented on the screen at
the next power up. A test is started by depressing the start button.
Thetestparametersaredenedasfollows:
Trigger: The load, in grams, measured by the CT3 to indicate that the probe is in contact
withthesample.Oncethetriggervalueisreached,thetestwillbeginatthedened
speed.BrookeldrecommendstriggervaluesasspeciedinTableII.1Setting
trigger value to zero disables trigger function so test will immediately start
from current position.
Deformation: The total downward distance the probe will travel once the trigger value is reached.
Speed: Thespeedatwhichtheprobewilltravelthespecieddistance.
Time: Thenumberofsecondsthattheprobewillbeheldatthedeneddistanceduring
a Hold Time test.
Count: The number of cycles (Speed and Distance) that will be applied to the sample
during a Cycle Count test.
