Portable Relay Test Set Vector Network Analyzer Secondary Circuit Test Tools

Portable Vector Analyzer , Multifunctional Phase Parameter Comprehensive Tester,Secondary Circuit Test Tools

I. Product Description and Advantages:

• Large screen dot matrix LCD display, can measure simultaneously, with the screen display of 16 parameters, such as U1,I1,φ1,U2,I2,φ2,U3,I3,φ3,φU1U2,φU2U3,φU3U1,φI1I2,φI2I3,φI3I1 and U1F.
• Voltage measurement resolution of 10 mV, current measurements up to the highest resolution 0.1 mA.
• In the measurement range of 45.00 ~ 65.00 Hz voltage frequency, resolution of 0.01 Hz.
• In the range of 0.0 ~ 360.0 °, measure the phase between U-U, U-I, I-I, the resolution of 0.1 °. While testing phase, require input voltage range of 10 ~ 500V, input current range of 10 mA ~ 120A. Void phase measurements with the symbol "..." indication to avoid that the operator will normally take the phase value "0.0 °" as a valid measurement when no signal is input.
• Direct dynamic or static vector graphics display system.
• After choosing ML250 clamp type current transformer, detect the polarity of the transformer, and direct display the ratio R (R = I1/I2) between I1 and I2 and the phase φI1I2 reflecting polarity between I1 and I2.
• Built-in memory save 50 group (panel) measurements data. By operating buttons on the panel access to the saved historical data sets and vectors.
• With RS-232 interface, instrument measurement data can be uploaded to a PC and formed a database for storage by PC management software, or print the report for file.
• Install rechargeable battery in it, the continuous working time is up to 15 hours or more when the LCD backlight is off, and for 11 hours or more when the LCD backlight is on.
• Using software calibration techniques, simple operation, reliable data, long-term stability.
