III. OPERATION
III. Principle
The Brookfield LFRA Texture Analyzer drives a probe through a set distance at a set speed into a
sample material that is placed (or fixed) on the base table. The LFRA offers a variety of probes,
fixtures, and test parameters to provide the user with a range of options for evaluating the texture
of a sample material. The following section describes the use of the LFRA.
III. Emergency Stop
The LFRA Texture Analyzer can operate with up to 4500g (4.5 kg) of force dependent
on load cell. Be sure to place only the sample for test under the probe. Keep body
parts and clothing away from the probe during the test.
The LFRA Texture Analyzer uses a compression force to evaluate a material. The user must take
care not to place any body part or clothing in the compression zone. The LFRA Texture Analyz-
er is provided with an Emergency Stop Button for use in case of an operational problem.
Pressing the Emergency Stop Button will cause three immediate actions: 1) Stop the test in
progress. 2) Return the probe to the top most position. 3) Reset the LFRA to the Emergency
Stop display, Figure III.1.

wise. This will reset the LFRA firmware to the power up condition.
