Toolbar (View Menu): The "Tool Bar" option is used to display or hide the Movie and Main Tool Bars. These tool
bars can be toggled by clicking this menu item on and off. If a Real-time window is active, this menu item
affects the Main Tool Bar. If a Movie window is active, this menu item affects the Movie Tool Bar.
Trigger Force: See "Triggering".
Triggering: Refers to the Recording Parameters dialog box. This dialog box allows you to .trigger. the start of a
recording based on a force value. If you enter a value in the .Trigger Force. field, and select the appropriate
measurement units, recording will not begin until that force is exerted on the sensor. Enter a zero in this field to
disable .triggering.. Only one Trigger Force value may be entered, and will apply to all sensors being used for
testing. See "Recording Parameters".
U
Uncalibrate (Tools Menu): The "Uncalibrate" command removes the sensor’s calibration data. When this item is
selected, a dialog box will appear, giving the option of canceling the Uncalibrate operation. Uncalibrate does
not affect the Sensitivity setting. See "Sensitivity".

Zeroing Preload (Tools Menu): The "Zeroing Preload" command modifies the calibrated data to correct for
residual pressure (referred to as the ‘Offset Load’) on the sensor at zero load. This operation is useful if the
sensor is under some load for the entire duration of the recording, or if the sensor must be secured in place by
hardware which would cause load to be detected by the sensor. The raw data is not affected by the Zeroing
Preload function, but an extra calculation is performed when converting the raw data to calibrated data. If the
sensel is reading raw pressure, it is set at zero raw before the calibration scale factor is applied. Zeroing
Preload is recommended only for single point calibration and may increase error when using a multi-point
calibration.
