Calibration Options
The Calibration Options are accessed by
touching the Calibrate key at the bottom of the
touch screen. The keys shown in the figure
below are displayed. A brief description of the
function of each key is provided in the table
below.
Key Name Description
TOUCH SCREEN Allows you to calibrate the touch screen display.
PROBE This procedure, sometimes called “initializing,” is used to calibrate zero force,
the LVDT, and the probe's compliance. It corrects for any difference in the
different probes used on the TMA and should be done every time you change a
probe on the TMA.
FORCE Force calibration calibrates the force exerted by the probe on the sample during
experiments using three different mass values (0, 50, and 100 grams) and can be
performed with any probe in place on the instrument. The first calibration point
is 0 grams. You may use weights other than the recommended 50 and 100 grams,
if desired (up to 100 grams is allowed). For example, you can use 10 grams for
force calibration if only low forces will be used in subsequent experiments.
This calibration should be performed periodically (approximately once a month).
