This parameter is the multiplier associated to the setpoint of the digital outputs.

The real setpoint must be calculated as follows:

setpoint alarm 1 = dig_on1 * 10

range_dig1

The variable “setpoint alarm 1” is to be considered in the format of the relevant variable (in this

example var_dig1) which can be an A-, V-, P-, D- or C-type (see paragraph 2.1.1).

Note:

(1)

the maximum value of the multiplier is depending on the variable type and on the instrument

model according to the following table.
