 +====== VC10TCoupleT ======
 +
 +The VC10TCoupleT function __Converts a voltage value, expressed in microvolts, to the corresponding temperature value, expressed in tenths of a Celsius degree, connected withe a thermocouple type T__.\\
 +Input range : from -5600 μV to 21000 μV\\
 +Output range : from -1998 °C<sup>-1</sup> to 4020 °C<sup>-1</sup>
 +
 +===== IMPLEMENTATION =====
 +
 +**VC10TCoupleT (mvhot, dgradi_hot, gbError)**
 +
 +Parameters:
 +
 +^IN/OUT^VARIABLE TYPE^EXAMPLE NAME^DIM^^
 +|  IN  |  GLOBAL  |  mvhot  |  L  |It is the voltage value to convert expressed in micro Volts.|
 +|  OUT  |  GLOBAL  |  dgradi_hot  |  L  |It is the converted temperature value expressed in tenths of a Celsius degree.|
 +|  OUT  |  GLOBAL  |  gbError  |  B  |Variable containing the error code|
 +
 +==== Error ====
 +
 +Once invoked the function if there are any errors the error variable having the following values:\\
 +0 - No error\\
 +1 - Value less than the minimum\\
 +2 - Value higher than the maximum\\
 +3 - Value indicating disconnected input
