当测得的功率因数等于或变得比拾取电平更滞后（即数值小于）时，PQM将操作用户选择的输出继电器。该输出可用于控制将电容连接到电路的开关设备，或向系统操作员发出警报。进入该状态后，当功率因数变得低于功率因数下降水平时，PQM会将输出继电器重置为非操作状态。除非所有三个电压均高于标称值的20%，且一个或多个电流高于0，否则功率因数1和2功能均被禁止运行。只有在所有相位上超过20%阈值时（当然，只有在功率因数保持在编程的拾取和丢弃水平之外时），才允许功率因数1和2延迟计时器计时。以相同的方式，
when the measured power factor is equal to or becomes more lagging than the pickup level (i.e. numerically less than), the PQM will operate a user-selected output relay. This output can be used to control a switching device which connects capacitance to the circuit, or to signal an alarm to the system operator. After entering this state, when the power factor becomes less lagging than the power factor dropout level, the PQM will reset the output relay to the non-operated state. Both power factor 1 and 2 features are inhibited from operating unless all three voltages are above 20% of nominal and one or more currents is above 0. Power factor 1 and 2 delay timers will be allowed to time only when the 20% threshold is exceeded on all phases (and, of course, only while the power factor remains outside of the programmed pickup and dropout levels). In the same way,
