S/N

Function

Built handle, that is, does not occupy space and convenient for users to carry instruments.

10.4-inch LCD touch color screen, multi-power intuitive display, full touch screen operation, more convenient operation.

The folding foot can raise the instrument by about 15° for optimal operation and reading view.

S/N

Function

Three-phase current fast connection terminal: the primary wiring can achieve a wide range of 0.2 mA ~120 A current measurement.

Three-phase voltage terminal: primary wiring can achieve voltage measurement of 6 V ~528 V.

Rich communication interface: including RS232, USB, LAN, easy for users to set up an automatic test system.

Shell ground: Make that the casing ground is reliably grounded before use.

Power interface: AC 220V power input interface with switch and safety pipe.

Pulse input terminal: from left to right, photoelectric pulse, electric energy pulse, synchronous signal and clock pulse PPS.

Pulse output terminal: from left to right is the electric energy pulse FL/ FH, Synchronous signal, clock pulse PPS 2.

Epitope difference / magnetic field measurement: it is used to measure the magnetic field in the 3 D magnetic field sensor; in the epitope difference sensor, it can measure the potential difference between the same phase voltage terminals of the multi-epitope device.

Temperature and humidity measurement: the temperature and humidity sensor is used to measure the temperature and humidity of the site.

• Each phase is equipped with a pair of fast terminals and wires, and the ac current of 0.2 mA ~120 A can be measured by direct connection, simplifying the wiring operation.

• Fully automatic switching range, the transformer does not shift at one time, no matter in which range suddenly into the large current will not lead to damage or measurement accuracy reduction

• The minimum measurement is limited to 0.2 mA, which can assess the accuracy and stability of the power / electric power of the R46 electric power device and its standard meter at the minimum starting current of 0.3 mA.

• There is complete electrical isolation between the voltage and current measurement circuits; in the limit state (500 V, 100 A), it will not damage the instrument, and can ensure the accurate value.

The main weight of the instrument is 9.9 kg and equipped with a special pull rod instrument box, which can put the host, test wire and laptop computer in it, and the transportation is very convenient. The notebook is equipped with special software meeting the requirements of JJG 597, which can automatically complete the error analysis, data recording, export or printing certificate of the device on site.

S/N

Function

The measuring channel has the function of oscilloscope, which can display the waveform of the measured power in real time.

Accurately measure the phase between the voltage and current of each phase, and show it intuitively in the form of the phasor diagram.

Calculate the harmonic distortion of THD / T (harmonic relative to full wave) and THD / F (harmonic relative to base wave).

The amplitude (RMS), content (%) and phase of the second ~ 127th harmonic of each phase voltage or current can be analyzed in real time, and the base wave measurement frequency is 45 Hz~65 Hz or 45 Hz~400 Hz optional;

It is used to check whether the harmonic content and phase of the complex waveform output by the R46 device meet the requirements of the procedure.

Show the frequency spectrum of each harmonic directly in the form of a bar chart (100%).

S/N

Function

Can choose full wave, base wave, single harmonic, harmonic section to measure power, electric energy.

It can be measured according to active power, reactive power and apparent power.

Harmonic section can be set to measure power or electric energy.

S/N

Function

Statistical analysis of data: calculate the maximum (Max), minimum (Min), peak-peak (P-P), the mean (Avg), the standard variance (S.dev) class.

Power stability test: during the test cycle, draw the curve of power change over time in real time.

Normal distribution histogram: displays the distribution of the counted power quantity during the test period.

Power stability test: the output power stability of the inspected electric energy device can be automatically calculated according to the algorithm of JJG 597-2005 "Verification Regulations for AC Electricity Meter Verification Device".

• Built-in small signal AC voltmeter, can measure the "potential difference between the same name buttons" of the device.

• The input terminal can continuously withstand a voltage of 250 V to prevent misaccess to 220V, and the high voltage causes damage to the internal voltmeter.

• Built-in standard second pulse input / output function, annual measurement uncertainty (k=2): 510-8

• The daily timing error of the device can be assessed.

• The built-in 3 D magnetic intensity meter for measuring weak magnetic signals has better performance than the ordinary one; the triaxial probe is not required to find the maximum magnetic field, which greatly improves the detection efficiency.

• The built-in environmental temperature and humidity measurement function can reduce the number of equipment carried by users to the site, and also save the initial investment.

• The rear panel of the instrument is equipped with RS232, USB, LAN and other rich communication interfaces, to facilitate the establishment of automatic test system.
