Impedance(Ω):{{0}}.0001~60.0 Resolution:0.0001
Admittance(ms):{{0}}.0001~60.0 Resolution:0.0001
In-phase Component: ΔX=±(X×2%+Y×2%)±Dx (with Class 1 to spare)
Orthogonal Component (with Class 1 to spare)
"X","Y"--Values Displayed
"Dx, Dy"--Quantified Error Dx=2, Dy=5
(4)Percentage: Class 2 (with Class 1 to spare)
Current:(1%－149%)In (In =5A)
(5%－149%)In (In =1A)
(2) Voltage:(5%－149%)Un (Un =100V, 100V/ √3V)
(5%－200%)Un (Un =100V/3)
(3) Voltage: (5%－200%)Un (Un =110V, 110/ √3V)
(1) Current: TO X＜{{0}}.12Ω cosΦ=1.0
(2) Voltage: a to x＜0.25VA (100V)
(1) Application of 320×240 LCD, broad vision, long life self lighting, making it convenient to operate.
(2) All English interfaces, simple and nice.
(3) Extra-large display of percentage, ratio error and phase error, easy to observe.
(4) Automatic sampling, rightly meet the need of JJG314-1993 and JJG314-1994.
(5) Automatic identification of polarity fault and ratio error mistake.
(6) Software can be upgraded with time.
(7) Completely solve the testing problems that Class S encounters.
(8) Automatic switch of measuring range.
(9) Perfect combination of advanced circuit technique and DSP; ultimately avoid the instability of the impedance phase differential circuit.
(10) Power consumption:
<15VA (with micro-printer)
<25VA (without micro-printer)
(11) Harmonic Suppression Ratio: >40db
