相位A/B/C最大视在功率信息将仅针对WYE连接系统显示。设置点S1 PQM SETUP\CLEAR DATA\CLEAR MIN/MAX POWER VALUES用于清除这些值。三相A/B/C PF最大值：这些消息中显示最大三相超前或滞后功率因数以及最大超前或滞后单个相位A/B/C功率因数。测量这些最大值的时间和日期也显示在这些消息中。该信息存储在非易失性存储器中，并在失去控制电源时保留。相位A/B/C最大超前或滞后功率因数信息将仅针对WYE连接系统显示。设置点S1 PQM SETUP\CLEAR DATA\CLEAR MIN/MAX POWER VALUES用于清除这些值。正方向的实际功率将增加到该累积值，而负方向的实际电力将增加到负瓦特小时值。
The phase A/B/C maximum apparent power messages will be displayed only for a WYE connected system. The setpoint S1 PQM SETUP \ CLEAR DATA \ CLEAR MIN/MAX POWER VALUES is used to clear these values. THREE PHASE/A/B/C PF MAXIMUM: The maximum three phase lead or lag power factor as well as the maximum lead or lag individual phase A/B/C power factor is displayed in these messages. The time and date at which these maximum values were measured is also displayed in these messages. This information is stored in non-volatile memory and will be retained during a loss of control power. The phase A/B/C maximum lead or lag power factor messages will be displayed only for a WYE connected system. The setpoint S1 PQM SETUP \ CLEAR DATA \ CLEAR MIN/MAX POWER VALUES is used to clear these values.3Φ POS REAL ENERGY: This message displays the positive watthours (in kWh) since the TIME OF LAST RESET date. Real power in the positive direction will add to this accumulated value, and real power in the negative direction will add to the negative watthour value.
