Smart ,filed calibration instrument
二.The latest features
1.32 bit high speed digital signal processor
it is for the first time adopt 32 bit with high s peed 50 MH2 DSP of IT and high performance 16bit AD with 12 channel on domestic ,the wide digital multiple with multi-functions was successfully developed by floating point operation to ensure that the filed data is accurate ,high stable , high reliable
2.can measured two meter error simultaneously or just only one 's ,which can improve not less than once work than traditional calibration method to measure error .
3. wiring simulation function
The maximum interval of automatic capture time can be set to 999 hour 60 min .the minimum interval time 1 min for Electric energy accumulation.
4.GPRS communication function , high- end system
All field data can be copy to the computer of official by GRPS or SMS ,it is helpful high-end system to solve the problem which happen on site offer advantages . if the instrument is installed with a wiring identifier inside ,then the high-end system will upload solution to instrument by also GPRS or SMS for field operator reference .by which ways can greatly reduce requirements for technical level of field personnel .
5.wiring simulation function
Instrument can be simulate the scene of variety of wiring and get corresponding the result of wiring in officer without access to voltage or current signal situation therefore .the function can be a use tool of checking line and also improve the skill for the field operation staff
6. self-checking for 5A clamp error
the inside of the instrument can produce (5A ,0.25A)current signal transferred to 5A clamp ,thus we can measure 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
7. the inside of the instrument is equipped with 512M storage space .
No load can also be identified wiring. when high supply high time.the minimum of starting current is 1mA
1.It adopt 7 inch ,16:9 industrial grade and width color screen of TFT , artistic .enough information .rich content .each function parameter of the instrument are directly and clearly display on the screen simultaneously .even if the sun shining are also so . Thus the user can clear seen out all data which appear on the screen when user .
2.The instrument can measured the active error .reactive error .voltage .current .active power .reactive power .phase .frequency .power factor . vector diagram simultaneously and measured results .
3.There is no adjustable resistance in the inside of the instrument .thus measured error need to amended by soft ware and get accuracy of data after revised
3.The display range of i current input way is up to 10000 times .
4. English version of the input method
5. we can choose the clamp mete (5A .100A.500A.1000A) to directly measure the ratio of low current transformer,by which we can conveniently found out some fault which happened in circuit breaker in CT two circuit,bad contact . short circuilt of ramp for internal of CT ,as well as the ratio of CT nameplate whether meet with the actual ratio of CT .
6.can real measurement of three-phase voltage and its current (A.B.C) ,as well as measured range of harmonic ( 2-21 times ) .let us to know power grid supply situation .
7.can measured the waveform for voltage and current og three -phase (A.B.C)
8. Wide power supply is 80V-480V
9.The instrument is installed on the USB can be directly connected to the computer with the function of data upload or copy.
10.all parameter need to input and all data for field range need to download can be set up freely by user the maximum can be accept 5000 users data on it
11.can measured all kind of electric energy meter on domestic and abroad .
