Intellectual Property Protection 浙公网安备 33010002000092号 Power up the wattmeter, power supply and multimeter and let them warm up for 30 minutes. However it is strongly discouraged to use this wattmeter directly on mains voltages, it is unavoidable that people will still do so, I want to give some instructions to limit the risks: The circuit diagram in figure 10 shows how the wattmeter is connected to a voltage source and the load. This ensures also that there is enough processing time left for the main program. Simultaneously the values are corrected for the sensitivity and calibration data. KOSTENLOSE Lieferung bei Ihrer ersten Bestellung mit Versand durch Amazon. 1 In Stock: 1: $79.87 : Buy. | 3: The analog input section of the wattmeter. Onetouch It is destined to measure active or reactive power in AC power networks.

Lazada, Browse Alphabetically: You can check the power consumption of your appliances through the digital reading on the meter. The same goes for measuring voltage and current and the selected parameter determines which property of the voltage or current is measured. Therefore the tasks are divided over four interrupt calls. If the voltage and current have the same polarity, the measured power is positive. Replace the Cdiv value in the code with this number. We'll assume you're ok with this, but you can opt-out if you wish.

Connect the voltage terminal to the point whereof the power must me measured, eg.

When choosing a range, anticipate to higher peak values rather than the nominal value. Nachdem Sie Produktseiten oder Suchergebnisse angesehen haben, finden Sie hier eine einfache Möglichkeit, diese Seiten wiederzufinden. 19,69 € 19,69 € 5% Coupon wird an der Kasse zugeordnet Sparen Sie 5% mit Rabattgutschein. The die-casting frame is alloy aluminum with excellent mechanical strength.

浙公网安备 33010002000092号 The measured values are unreliable if there is an overload indication. The ADC measures three inputs: the input voltage, the current and the null-reference.

The new voltage conversion factor is calculated as: | The meter deflection is proportional to the VI, which is power. To calibrate the wattmeter, a reliable multimeter and a stable adjustable power supply is needed.

This secondary averaging is done with an array to get a more flowing presentation of the measured parameters. Amateurfunk HF-Wattmeter RF-Powermeter. How Power Meters Work. To convert this in the common used Ampere*hour (Ah), divide the reading by 3600. Accept Read More, The ohm meter is an instrument used to determine resistance. |

The wattmeter measures the energy in the SI-unit: Joules (J), or Watt*seconds (Ws). After this adjustment, calibrate the voltage and current range again to confirm the accuracy.

To reset the parameters: hold down the fourth button (reset) and press the first button (line select). Entdecken Sie jetzt alle Amazon Prime-Vorteile. Four times per second all the parameters are calculated as floating point numbers from the averaged and directly from the ADC obtained values and put in the result array. This is not feasible with the standard Arduino analogRead function. Notes . First of all: don't use an external adapter.

At the same time an indicator "^" at the affected parameter is shown between the value and unit. This article incorporates text from a publication now in the public domain: Chisholm, Hugh, ed.

Considering the amount of calculations that is performed by the interrupt routine, the sample frequency is set at 19231 Hz. The conversion from the raw ADC-values to the real voltage and current values is done with a scale factor: For voltages this is Vscale = ADCsense * Vdiv, and for current Cscale = ADCsense * Cdiv. The wattmeter uses fixed coils to indicate current, while the movable coil indicates voltage (as shown in below Figure).

Bitte versuchen Sie es erneut. The wattmeter is an instrument which measures DC power or true AC power. Both number must be filled in the code under "Calibration & Hardware Data" as shown in the code section below.
