micro field calibration instrument
Products model :QAS-1D

micro field calibration instrument

二.the latest function
1adopt.32  bit high speed 150MHZ DPS of IT ,high performance of 16-bit  AD with 6 channels
The digital multiplier with multi-function was successfully developed by floating point operation to ensure the accuracy of calculation

2.No- load  can also check line function .
 can correctly check line without  no-load or small current  situation  for  user

3.wiring simulation function
Instrument can be simulate the scene of variety of wiring and get corresponding the result in officer without access to voltage or current signal situation . Therefore .the function can be a use tool as checking line  and improve the skill for the field operation staff .

4. self-checking for 5A clamp  error
the inside of the instrument can produce 5A current signal transferred to 5A clamp.thus we can measure the error of clamp meter .
Thinking into account 5A clamp has a 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 and remind relevant staff timely to clean clamp bite .

5.Ultra wide current measuring  range
500 times current range to ensure measuring  index :1000 times current display range ..
The minimum starting current is 1mA, NO-LOAD also can identify the wiring when high supply high time

6.Electric energy accumulation function
a.  can  calibrate  electric energy meter without electric energy  pulse output, or as a test  of energy saving index

b. using 4.7 inches   16:9 industrial grade and wide color screen of TFT ,artistic  .enough information .rich content  .each function  parameter of  the instrument are directly  and clearly  display on  the screen simultaneously without turning .  this can make them  to be clear  at a glance when the user  to see this function on it .

c.   can be measure electric energy error ,voltage .current .active power .reactive power .phase. frequency .power factor (PF) and display vector diagram  simultaneously ,as well as calibate results.

d.    There is no install adjustable resistance  in the inside of the instrument , all errors need to revised d by software
e.     English version  input method

f.       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 circuit of ramp for internal of CT ,as well as   the ratio of  CT nameplate  whether meet  with the actual ratio of CT .

g      .can real measurement  of three-phase  voltage  and its current (A.B.C)  ,as  well as  measured range of  harmonic ( 2-51 times )  .let us to know power grid supply situation .

h  .can measured the waveform for voltage and current og  three -phase (A.B.C)

I .Wide power supply is 45V-480V

J. all parameter need to input and all data  for field range need to download can be set up freely by user ,which can be connected with a number of systems to achieve the funtion of data's download and upload .
