The main functions and features:

1, Measuring transformer no-load loss, no-load current, heavy load loss, impedance voltage, zero sequence impedance, short-circuit impedance, voltage effective value, average value of voltage, current, power, power factor, frequency and other parameters.

2, All data are in the same period synchronous measurement, to ensure the measurement results are accuracy and rationality under the city power.

3, Automatic waveform distortion correction, voltage correction, the current correction, temperature correction, without any manual calculations.

4, Within instrument allow the measurement range can be directly measured, exceeds measuring range can external connection a voltage and current mutual inductor.

5, Locking display data, storing (100 times) or printing all measurement results, the instrument was built-in do not power-fail memory and mini-printer, can be stored for a long time measurement data , can print and refer at any time.

6, Large screen LCD display, all Chinese characters menu and operation tips, intuition and convenient.

7, Do not power-fail the calendar clock function.

8, With RS232 interface, can communication with computer.

The main technical indicators:

1, The basic measurement accuracy: voltage, current, plus or minus 0.2%

Power plus or minus 0.5% (COS φ >0.1), plus or minus 1.0% (0.01)

2, Voltage measuring range: AC0~450V

3, Current measuring range: AC0~50A

4, Volume: 350*270*120mm

5, Weight: 6Kg (excluding test line)
