設(shè)置時(shí)間/日期：這些消息用于設(shè)置PQM軟件時(shí)鐘的時(shí)間和日期。PQM軟件時(shí)鐘保留約一小時(shí)的電源中斷?？梢詥⒂脮r(shí)鐘未設(shè)置警報(bào)，以便在時(shí)鐘數(shù)據(jù)丟失時(shí)發(fā)出警報(bào)。時(shí)間和日期用于所有帶時(shí)間戳的數(shù)據(jù)。如果尚未設(shè)置時(shí)鐘，則所有時(shí)間戳數(shù)據(jù)的顯示時(shí)間右側(cè)將顯示“？”。按照以下步驟設(shè)置新的時(shí)間和日期。時(shí)間和日期也可以通過Modbus通信設(shè)置。有關(guān)計(jì)算參數(shù)示例，請(qǐng)參閱第7.2.10節(jié)功能代碼16-廣播命令。PQM可編程為通過各種方法計(jì)算計(jì)量量和需求。XTRACT基本信息：PQM可被編程為使用真實(shí)RMS值或采樣數(shù)據(jù)的基本成分計(jì)算所有計(jì)量量。當(dāng)該設(shè)定值設(shè)置為DISABLE（禁用）時(shí)，在進(jìn)行計(jì)量計(jì)算時(shí)，PQM將包括所有諧波含量，最高32次諧波。
SET TIME/DATE: These messages are used to set the time and date for the PQM software clock. The PQM software clock is retained for power interruptions of approximately one hour. A CLOCK NOT SET alarm can be enabled so that an alarm will occur on the loss of clock data. The time and date are used for all time-stamped data. If the clock has not been set, a “?” will appear on the right-hand side of the displayed time for all time-stamped data. Follow the steps shown below to set the new time and date. The time and date can also be set via Modbus communications. Refer to section 7.2.10 FUNCTION CODE 16 - BROADCAST COMMAND for an example Calculation Parameters The PQM can be programmed to calculate metering quantities and demand by various methods.XTRACT FUNDAMENTAL: The PQM can be programmed to calculate all metering quantities using true RMS values or the fundamental component of the sampled data. When this setpoint is set to DISABLE, the PQM will include all harmonic content, up to the 32nd harmonic, when making metering calculations.
