B: Main functions and features
1. It can semi automatically or manually inspect the basic errors of various power frequency meters (voltmeter, ammeter, power meter, frequency meter, power factor meter, phase meter) in the power system, as well as the changes caused by factors such as voltage, current, waveform, and power factor.
The power supply section can generate distortion waves with harmonics ranging from 2nd to 31st, and the number, order, amplitude, and phase of harmonics on the fundamental wave can be programmed.
The working frequency band of the 3 power amplifiers is 40H_Z～1kH_ZHas good linearity. The current amplifier is a constant current source, and the voltage amplifier is a constant voltage source. Due to its lightweight, this device is more suitable for on-site verification.
4. Equipped with RS-232 interface. Through the upper computer software (optional), this device can be controlled by a computer for automatic or manual inspection, and the results can be processed and managed.
5. Equipped with a large capacity non-volatile memory, it can store 300 pieces of raw data from the tested instruments for reference and uploading.
6. The electricity meter can be calibrated by detecting the load point or selecting the point according to the electricity meter.
