The following diagram illustrates the relationships.

Example 2:
The reactive power Q is to be output over analog output D1 with a sign and between 4 to 20 mA. A reactive
power Q = 0 % is to be equivalent to a current value of 12 mA. 80 % is sufficient as reference value because
the reactive power is referred to the nominal apparent power of the protected object.
We thus obtain the following settings:
Address 7330 MIN. VALUE D1/2 = -80%
Address 7331 MIN.OUTPUT D1/2 the minimum current output value in mA, = 4 mA
Address 7332 MAX. VALUE D1/2 = 80%
Address 7333 MAX.OUTPUT D1/2 = 20 mA
We thus obtain the relationships between measured values and current output values shown in the following
illustration.
