Tyco 1540 - Manual (Page 40)

In the example above, the unit has an analogue output range of 0 to 1 mA, all power is imported
and the load is inductive. The 1 mA Output range covers a reading power factor range of 0.6,
from 0.9 capacitive to 0.5 inductive. The capacitive overlap is provided in case of over-
compensation of power factor. The Output to Reading correlation is as follows:
Reading European Convention North American Convention
Output Output
0.9 PF cap. 0 mA 1 mA
1 PF 0.167 mA 0.833 mA
0.9 PF ind. 0.333 mA 0.667 mA
0.8 PF ind. 0.500 mA 0.500 mA
0.7 PF ind. 0.667 mA 0.333 mA
0.6 PF ind. 0.833 mA 0.167 mA
0.5 PF ind. 1 mA 0 mA
