Each two points are connected by a straight line and the whole curve represents the relationship between the input value and the display value. In order to obtain more accuracy in the measuring it is recommended to program the highest possible number of points and reduce the segment length.

    4.1.1 Programming of the scale There are two methods for programming the scale, the SCAL method and the tEACH method. In the following diagram the SCAL menu is shown as an example; it is exactly the same menu as the tEACH menu.
  • Page 29 tEACH method Level 2 The input values are introduced directly from the signal present on the input connector when each point is programmed. The display values are programmed manually. This method can be used when it is possible to bring the process to the conditions of each one of the points to be programmed.

Three different functions may then be added to the functions available from the front panel keys. Each function is allocated to a pin (PIN 2, PIN 3, PIN 4) that is activated by applying a low level to each one with respect to PIN 1 or COMMON.
