2. PRINCIPLE OF OPERATION
a) The QTS25 consists of a bi-directional loadcell located in a cantilever beam, which is
driven by an electronically controlled motor drive system, to enable linear travel
within a user selectable range of 0.01mm to 420mm in increments of 0.01mm.
b) The sequence of linear movements of the beam is programmable by use of either the
"QTS Controller" keypad or dedicated software packages.
c) The use of the "QTS Controller" keypad is described in the following sections.
d) After programming a test method and fixing an appropriate probe or fixture to the
loadcell, the test is started using the 'Run Test' key. The probe travels at pre-set slow
speed until a sample is detected, this is the trigger point. From this point the probe
begins the programmed test sequence and the keypad provides a continuous display
describing the beam movement and test results.
