The parameters of the products

1 , Working environment
  1 ) Temperature : 5 ℃ ~ 40 ℃; Relative humidity : <80% (25 ℃ when )
    Altitude : <2500m
    Power frequency : 50Hz ± 0.5Hz; Supply voltage : 220V ± 5V
 2 ) Measuring range:
    Phase component ( % ) : 0.0001 ~ 200.0 ; Resolution : 0.0001
    Quadrature component ( stars ) : 0.001 ~ 700.0 ; resolution: 0.001
    Impedance (Ω): 0.0001 ~ 20.0; Resolution : 0.0001
    Admittance (ms): 0.0001 ~ 20.0; resolution: 0.0001
 3 ) Basic error:
    Phase component : ΔX = ± (X × 2% + Y × 2%) ± Dx ( with an optional )
    Orthogonal components : ΔY = ± (X × 2% + Y × 2%) ± Dy ( with an optional )
              "X", "Y" - the instrument display
              "Dx, Dy" - the quantization error of the instrument
               Dx = 2, Dy = 5
  4 ) dial indicator : level 2 ( level 1 available )
2, Scope of work:
 1 ) Current : (1% ~ 149%) In (In = 5A)
          (5% ~ 149%) In (In = 1A)
  2 ) Voltage : (5% ~ 149%) Un (Un = 100V, 150V, 100V /)
          (5% ~ 149%) Un (Un = 100V / 3)
3, the working load:
  1 ) Current : TO right TX <0.12Ω cosΦ = 1
  2 ) Voltage : a pair of x <0.25VA (100V)
4 , wrong polarity indication
  When the operating current ( voltage ) reaches the rated current ( voltage ) of more than 5% error for more than 180 %, the proper polarity indication .
  Note: If greater than the rated operating current ( voltage ) more than 10% , should not appear polarity indication , there is a fault , please do not increase the current
  ( Voltage ) , so as not to burn the instrument .
5 , ratio error indication :
  When the operating current ( voltage ) reaches the rated current ( voltage ) of more than 5% error of more than 30% but less than 180% , the proper ratio error indication.
6 , insulation and pressure test and description:
  Terminal TX () terminals connected
  Power outlet on the casing can withstand 1.5kV, 1min pressure


Power supply: AC110V/115V/120V/127V/220V/230V/240V optional
Input frequency: 50Hz/60Hz optional
Note: The users can select the corresponding power which based on their local supply voltage and frequency, and we will confirm it before the delivery (or inform us that the goods will be used in which country advance)
