频率：此消息显示频率（Hz）。频率根据A-N相电压（当设定点S2 SYSTEM SETUP\CURRENT/voltage CONFIGURATION\VT WILING为WYE时）或A-B相电压（设定点S2系统设置\电流/电压配置\VT WIRING为DELTA时）计算。如果施加到PQM端子的电压不足（A相上的电压低于30 V），则显示值0.00。FREQUENCY MIN（频率最小值）：此消息显示测量的最小频率以及出现最小频率的时间和日期。S1 PQM设置\清除数据\清除最小/最大频率值设置点清除这些值。FREQUENCY MAX（最大频率）：此消息显示测量的最大频率以及出现最大频率的时间和日期。S1 PQM设置\清除数据\清除最小/最大频率值设置点清除这些值。
FREQUENCY: This message displays the frequency (in Hz). Frequency is calculated from the phase A-N voltage (when setpoint S2 SYSTEM SETUP \ CURRENT/VOLTAGE CONFIGURATION \ VT WIRING is WYE) or from phase A-B voltage (when setpoint S2 SYSTEM SETUP \ CURRENT/VOLTAGE CONFIGURATION \ VT WIRING is DELTA). A value of 0.00 is displayed if there is insufficient voltage applied to the PQM’s terminals (less than 30 V on phase A). FREQUENCY MIN: This message displays the minimum frequency measured as well as the time and date at which the minimum frequency occurred. The S1 PQM SETUP \ CLEAR DATA \ CLEAR MIN/MAX FREQUENCY VALUES setpoint clears these values. FREQUENCY MAX: This message displays the maximum frequency measured as well as the time and date at which the maximum frequency occurred. The S1 PQM SETUP \ CLEAR DATA \ CLEAR MIN/MAX FREQUENCY VALUES setpoint clears these values.
