Product features
Multifunctional test function
The power meter with same specifications, different constants and different communication protocols can be checked.
The harmonic test function, the 1~21 harmonic is set arbitrarily, and the harmonic influence test is carried out.
Automatically calibrate the period of demand.
It can simulate on-the-spot operation for time interval switching and combination error test.
The timing error is tested by a high precision clock tester with a precision of 10-7.
Correspondence test;
When GPS broadcast the school, the data in the table is verified, reading and writing the meter number.
Time zone time interval testing and setting;
Measured value error test;
In accordance with the requirements of verification regulations, automatic verification can be carried out for verification items such as sneaking, starting, basic error and standard deviation.
Can carry out positive and negative phase sequence test, positive and negative power test, four quadrant reactive power test;
Voltage impact test, frequency effect test and voltage unbalance influence test can be done.
It can receive all kinds of pulse input signals, including mechanical dial, light emitting diode, infrared diode, electrical pulse and so on.
Functional characteristics
The cabinet and the aluminum alloy hanging rack are divided into two parts, beautiful and light.
