Product Description


IIntroduction

DFC***3A is a three phase portable reference meter, which is used to check many kinds of electricity meter. With small size, light weight, strong function, it is the best tool to check meter on-site.

DFC***3A use Analog to Digital Conversion (ADC) be the fundamental principle, sample the voltage and current. Digital signal processing unit control the sample and analysis the data in real time. It uses high-precision sampling technique and advanced signal processing technology, so the system accuracy is better than 0.*5% in wide voltage and current range.

II. Features

1. Function: Measure Voltage, Current, Vector, Waveform Distortion, Harmonic, Active Power, Reactive Power, Apparent Power, Phase, Power Factor, Frequency, Energy Error.

2. Power measurement: 

DFC***3A can measure the power below:

(1) Three-phase four-wire active power

(2) Three-phase three-wire active power

(3) Three-phase four-wire true reactive power

(4) Three-phase three-wire true reactive power

(5) *0°-balancing, reactive energy, triple-system

(6) *0°-balancing, reactive energy, cross-connected system

(7) Three-phase four-wire apparent power

(8) Three-phase three-wire apparent power

3. Wide range: Voltage *0V***0V, Current 1A,*0A, Auto switching range/Manual switching range.

4. Four quadrant three-phase simultaneous measurements for active, reactive, and apparent energy and power.

5. Receive high/low pulse from electric meter to compute error.

6. High/low standard electric pulse output.

7. Voltage and current harmonic analysis: ***1th harmonic content.

8. Complete software calibration, to eliminate the drawback of hardware calibration.

9. Built-in lithium battery, auxiliary power supply can be AC or battery. In outdoor use, it can be supplied with the electric wire. 

IIISpecifications

Note: In these specifications,”RD” is short for “read”,”RG” is short for “range”.

1. Voltage Measurement
