(stainless steel, aluminum) to plastics (acrylic, Black Delrin, Nylon). Clean with a nonabrasive cloth using solvents that are appropriate for both the sample material and the material of the probe and/or fixture. Do not apply excessive upward, downward or sideways force to probe while fixed to CT3. Damage may occur to the load cell. AMETEK Brookfield Page 11 Manual No. M08-372-F1116... -
Page 12: Quick Start
Set the test speed and distance. See Section IV.3 for more information. Press the START button. The weight of the probe will autozero and then the test will start. Record all test results. Remove sample and clean the probe. AMETEK Brookfield Page 12 Manual No. M08-372-F1116... -

2) The probe immediately returns to the home position. 3) The Emergency Stop condition can be canceled by rotating the Emergency Stop Button clockwise. This will reset the CT3 firmware to the power up condition. Tension: Pressing Emergency Stop Button during a tension test will: 1) Immediately stop probe movement and display the emergency stop screen. AMETEK Brookfield Page 13 Manual No. M08-372-F1116... -
Page 14: Iii.3 Base Table
The Rotary Base Table (P/N TA-RT-KIT) is a disc shaped surface and should always be centered under the probe when conducting compression tests. There are two methods of adjusting the height in order to place the sample close to the probe for testing. The locking knob on the base of the Rotary Table allows quick height adjustment; just unlock the knob, raise or lower the table, then lock it into position. The table is also mounted on a threaded shaft held securely with a fine adjustment nut. Unlocking the fine adjustment nut and rotating the table will raise or lower the test surface to give even more range to the height adjustment. AMETEK Brookfield Page 14 Manual No. M08-372-F1116... -
Page 15: Iii.4 Probes
There are a range of fixtures available for use with the CT3 Texture Analyzer as described in Appendix A. These devices are designed to hold a sample in place during measurement. Each fixture is designed to attach to either the Rotary Base or Fixture Base Table. Refer to the instructions provided with the fixture for proper installation. NOTE: Brookfield can design custom fixtures to meet your application. Contact AMETEK Brookfield or your local authorized dealer for details. AMETEK Brookfield Page 15 Manual No. M08-372-F1116... -

Page 22: Bloom Test
TPA TEST – performs two compression cycles on the sample and reports five established Texture Profile Analysis results. The operator sets the trigger value, target deformation (travel distance into the sample) and the test speed using the TPA menu screen: AMETEK Brookfield Page 22 Manual No. M08-372-F1116... - Page 23 Adhesiveness is a measure of stickiness and is calculated as the area under the negative peak as probe withdraws after the first compression. TENSION TEST – this test can be used to pull apart a sample, usually using grip fixtures to apply tension load on the sample. AMETEK Brookfield Page 23 Manual No. M08-372-F1116...

When clamping the sample try to exert only minimal lateral loads on the probe shaft. Pressing Start as shown below will start the test: *CLAMP SAMPLE *PRESS START TO CONTINUE Figure III.25 During the test the running screen is seen as shown below: TEST: TENSION DEFORMATION:XXXX.X mm LOAD: XXXX.X Figure III.26 AMETEK Brookfield Page 24 Manual No. M08-372-F1116... - Page 25 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 AMETEK Brookfield Page 25 Manual No. M08-372-F1116...

Page 29: Surimi Test
The test speed for all surimi testing has historically been 1 cm/s, so this is the default value. The test speed can be set from 0.1 mm/s to 10 mm/s, which is equivalent to 1 cm/s. Changing the test speed is likely to change the gel result. AMETEK Brookfield Page 29 Manual No. M08-372-F1116... -
Page 30: Iii.8 Global Parameters
It may be set from 0.1mm/s to 10.0mm/s. For some tests, Such as TPA, the post test speed is irrelevant because it will always be the same as the test speed. The two tests for which this is the case are TPA and the Cycle test. Rotate the Select Knob to LOAD UNITS. When the cursor is over the “L” in LOAD, pressing the Select Knob will reposition the cursor to the “g” or “N” at the far right of the field. Rotating the knob will alternate between the “g” and “N” (grams and Newtons). AMETEK Brookfield Page 30 Manual No. M08-372-F1116... -

This was left to ensure that a complete break between probe/sample interface was made during probe retraction so that adhesiveness characteristics could be evaluated.
