Figure 64: Impedance characteristic
Complex characteristic can be formed with the ZQMPDIS ( 21) function. Figure 65 shows
for example, when zone 1 is set to combined quadrilateral and mho characteristic, zone 2
is set to forward mho characteristic, zone 3 is set to reverse mho characteristic and, zone
4 and 5 are set to quadrilateral characteristic.
