La description

{

  1. Check the error of active and reactive of watt-hour meter at the same time, and meanwhile check the error of main and secondary meter in the same circuit.

2.     Display the electrical constants such as: voltage, current, power, power factor, phase and frequency and etc.

3.     Measure CT ratio, wave form display.

4.     Measure ***1 voltage and current harmonics.

5.     Judge wrong wiring.

6.     Measure the baud rate for multi-function energy meter and meter number reading.

7.     PT、CT secondary loading function.

8.     Automatically correct the Clamp error.

9.     U disk upgrading system, download the calibration data to achieve paperless office.

*0.   Battery power supply or wide voltage (*7.7V***0V) online power supply/charging.

*1.   Accuracy: class 0.*5, class 0.1.

Main Functions:

1.     High differentiation color screen display.

2.     Simultaneously measure active/reactive power、voltage、current、frequency、phase position and other parameters and these parameters are corrected by the software.

3.     The device is WITHOUT potentiometer, which totally avoids the error change due to the transportation, and greatly increases the stability and reliability.

4.     Clamp self-calibration function, which ensure the high-accuracy stability of the clamp.

5.     Mutual check between phases, which ensure the accuracy stability of the device for long term.

6.     Measure reactive without the affect by voltage/current unbalance、phase angel asymmetric、frequency change and etc. And the accuracy for the reactive can reach to 0.1%.

7.     Energy accuracy is class 0.*5 or class 0.1.

8.     Can be with 5A clamp with class 0.2.

9.     Can be with clamps of *0A、**0A、**0A、***0A to measure the composition error. If with 5A clamp, it can measure CT ratio.

*0.   Voltage range: *0V～**0V, current direct 5A.

*1.   Wide working power source: AC *7.7～**0V, and battery power supply(no need connected to recharger).

*2.   Display *8 wiring mistakes for three phase three wire, display *6 wiring mistakes for three phase four wire and display any Connection hexagon chart.

*3.    Three phase voltage/current wave form display, and measure and save 2～*1 harmonics data.

*4.   Can save all measured data for ****0 meters.

*5.   Can communicate with PC, downloading data to PC or software upgrading by U-disk or port.

*6.   Can test the energy meter automatically or manually.

*7.   Can also test the transducer.
