+Maximum isometric force
+\end_layout
+
+\begin_layout Standard
+Chronojump allows, using a sensor force, to perform a test of maximum isometric
+ force to measure some parameters like:
+\end_layout

+This parameters can be measured from:
+\end_layout

+\begin_layout Itemize
+Real force or raw data (Black).
+\end_layout
+
+\begin_layout Itemize
+Modeled force using an inverse monoexponential function (Blue).
+\end_layout
+
+\begin_layout Standard
+The RFD refers to Rate of Force Development.
+ This variable is the derivative or the slope of the function force versus
+ time.

+\end_layout

+\end_layout

+Taring
+\end_layout
+
+\begin_layout Standard
+The taring process consists in indicating at which state the sensor should
+ register a force of zero Newtons.
+\end_layout
+
+\begin_layout Standard
+To perform this process put the sensor in a horizontal and stable surface
+ and, without supporting any external force apart from the weight.
+ Then press the button

+Calibration
+\end_layout
+
+\begin_layout Standard
+The calibration consists in stablishing a lineal relationship between the
+ electrical signal of the sensor and the real force.
+ This relation could change in function of the sensor, temperature, humidity...
+ For this reason it is recommended to calibrate once per session.
+ By default Chronojump will use a generic calibration.
+\end_layout
+
+\begin_layout Standard
+To perform the calibration, in Chronojump enter the mass in kilograms of
+ an object with a known weight.
+ Tie this object to the force sensor and lift it making the sensor to hold
+ all the weight.

+Each value of the RFD can be calculated from two types of signals:
+\end_layout

+\begin_layout Itemize
+The Raw signal shows the values of force registered by the sensor during
+ the test.
+ All that is refered to this signal will be black.
+\end_layout
+
+\begin_layout Itemize
+The fitted signal refers to the inverse monoexponential function that better
+ fits the raw data.
+ This fitting is made adjusting the Fmax (maximum force) and K (the speed
+ at which the maximum force is reached)

+Besides, the RFD can be calculated in various ways:
+\end_layout
+
+\begin_layout Itemize
+Instantaneous.
+ The RFD is calculated at the instant specified in milliseconds.
+\end_layout
+
+\begin_layout Itemize
+Average.
+ The RFD is calculated measuring the increment of force between two instants,
+ specified in milliseconds, divided by the elapsed time.
+\end_layout
+
+\begin_layout Itemize
+% Force max.
+ The RFD is calculated in the instant when the force is equal to a percentage
+ of the maximum force.
+\end_layout
+
+\begin_layout Itemize
+RFDmax.
+ The RFD calculated is the maximum of the test.
+\end_layout

+\begin_layout Standard
+In all cases the RFD is plotted as a line with a slope equal to the RFD
+ and located at the points specified.
