Features:Thephysical layer adopts UART to RS485 communication interface, with baud rate of 9,600, 8-bit data bits, 1-bit stop bits and no verificationThis Multi-function Metercan measure voltage, current, power, power, frequency, power factorOver power alarm: Active power threshold can be set, when the measured active power exceeds the threshold, it can alarmIt can display six measurement parameters on the computer when communicate through the softwareThe high test accuracy, better compatibility will make it use widely.Specifications:Brand: PEACEFAIR Model: PZEM-016Type(Optional): Type1: 1*Meter+1* Closed type CTType2:1*Meter+ 1*open type CTType3:1*Meter+ 1*Closed type CT+ 1*USB to 485Type4:1*Meter+ 1*open type CT+ 1*USB to 485VoltageMeasuring range:80~260VResolution: 0.1VMeasurement accuracy: 0.5%CurrentMeasuring range: 0~100AStarting measure current: 0.02AResolution: 0.001AMeasurement accuracy: 0.5%Active powerMeasuring range: 0~23kWStarting measure power: 0.4WResolution: 0.1WDisplay format:When the data is 1000W, it display one decimal, such as: 999.9WWhen the data is 1000W, it display only integer, such as: 1000WMeasurement accuracy: 0.5%Power factorMeasuring range: 0.00~1.00Resolution: 0.01Measurement accuracy: 1%FrequencyMeasuring range: 45Hz~65HzResolution: 0.1HzMeasurement accuracy: 0.5%Active energyMeasuring range: 0~9999.99kWhResolution: 1WhMeasurement accuracy: 0.5%Display format:When the data is 10kWh, the display unit is Wh(1kWh=1000Wh), such as: 9999WhWhen the data is 10kWh, the display unit is kWh, such as: 9999.99kWhReset energy: use software to reset.Communication interface: RS485 interfaceSize:90 x 60.5mm / 3.54 x 2.38inWeight: Approx.118~154gPackage includes:Type1,Type2,Type3,Type4 (Optional)Type1: 1*Meter+1* Closed type CTType2:1*Meter+ 1*open type CTType3:1*Meter+ 1*Closed type CT+ 1*USB to 485Type4:1*Meter+ 1*open type CT+ 1*USB to 485
