1.3 Optional arbitrary one or more harmonic to calculate the harmonic compound of U. I. P. Q. VA and its percentage as well as harmonic wave active power of electric energy.

 

1.4 Can simultaneously single analysis component and measure value of each time U.I.P.Q.VA of three-phase harmonic wave and display its 51 time+PH /-PH  and percentage of fundamental wave to ensure influence of positive and negative harmonic on the metering. 

 

1.5 full wave reactive power is the algebraic sum of the reactive power of fundamental wave and harmonic wave at a turn.in order to avoid 90 degree phase shift in the past and in the case of harmonic wave reactive power test error .we can measure the brand with of electrical energy meter that can be detected and choose the number of each harmonic wave.

 

1.6 Can be simultaneously test two pulse that can be detected also test the pulse constant that tested too as well as work ways and completely different pulse number. 

 

1.7 Overload 2.4 times, all measurement points can ensure that the accuracy of 0.05% and also guaranteed the measure index of CT two rated current when it is 1mA .500 times current range ensure measure indicator.

 

1.8 500 times current range ensure measure indicator,1000times current display range .the minimum of 1m A starting current .high for high time .no load can be identified wiring.

 

1.9 Electric energy accumulation function can measure the electric energy meter that has not pulse output.

 

1.10 Display vector diagram can identify three-wire of 48 wrong wiring and four-wire of 96 wrong wiring as well as CT two cross wiring.

 

1.11 Adopt 7 inch 16:9 industrial grade and width color screen of TFT. Each function parameter of the instrument are direct and clear display on the screen simultaneously without turn screen .allow users to use at a glance. 

 

1.12 Instrument can be simulate the scene of variety of wiring and get corresponding the result of wiring and revised parameter in officer without access to voltage or current signal situation therefore ,the function can be a use tool of checking line and also can improve the skill for the field operation staff.

1.13 Instrument internal can produce the actual current signal of 0.05-5A and added into 5A clamp to check the error of clamp meter . thinking into account 5A clamp has  error change problem after being used for a long time.we should keep know the situation of closure about the clamp meter at any time . remind relevant staff timely to clean clamp bite,on the change of 5A clamp ,the error can be amend 0.2 grade.

1.14 Can be automatic input the number and code of electric energy meter(matching function) and support bar code scanning gun

 

1.15 Can read the total base number of active power and reactive power of multi-function electric energy meter (Apex, peak, flat, valley) by use 485 or Infrared electric head, read constant and correcting time. Support provision of the national standard DL645-1997 DL645 and DL645-2007.(optional feature)

        1.16 Instrument inside with 2G electronic disk.

 

1.17 Can connect 3 inches field printer battery directly with battery power supply converted the color screen to black and white being printer.

 

1.18 Using the clamp meter (5A100A500A100OA) directly to measure the ratio and ratio error of low voltage current transformer.

 

      1.19 Show the voltage and current waveform of three phase A.B.C.

 

1.20 Work power input range is 55V-600V.the normal three-phase voltage input industrial socket is 600V. Industrial switches switching connection city electric and three phase voltage as work power. 

 

1.21 all parameter need to input and all data for field range need to download can be set up freely by user .it can storage 5000 user data.

 

         1.22 Can be store the current screen to U disk.

 

1.23 Have temperature and humidity measurement (need to install temperature and humidity sensor).

 

       1.24 With USB port can connect U disk,the formation of super larger space convenient data copy.

 

1.25 Touch screen and press key operation, enter the keyboard using a computer keyboard column arrangement. Can also use the PC interface of the USB computer keyboard.

 

       1.26 Can adjust time by USB interface and PC machine.

 

1.27 The plat computer can directly control the instrument .operation interface same as instrument operation interface.

 

1.28 Voltage measurement socket and power switch switching for industrial grade can be used under 600V (ordinary city electric switch is 250V, in 380V for the use of the super range there are security risk).

 

1.29 High security design. city electric socket, voltage measurement socket, current input, between current clamp input is withstand voltage 4kv, separately isolated.

 

1.30 Electric energy pulse input protection.when input high voltage it will automatically start protection and display prompt message on the instrument .once the error correction.click on the interface to reset the protection.

 

1.31 The 5A clamp has self correcting function: the 5A's current signal is generated internally by the instrument added to the 5A clamp to measure the error of the clamp meter.

 

1.32 5 low power ARM chips are used, all calculating ability is greater than 1GIPS, and all parameters of the 51 harmonic and the full wave are calculated at the same time.

 

1.33 Using CE windows operating system with mature and genuine.its function is stable and reliable.
