Purpose and characteristics

The HG1365 multifunctional standard table (hereinafter referred to as the standard table) is an intelligent multifunctional standard table with a 240 * 320 high brightness backlit LCD screen display and a good human-machine interface. This standard table adopts the latest technologies such as high-speed DSP and 100K sampling rate, high-speed A/D converter with self calibration, etc. to sample AC signals at high speed, and adopts special data processing methods to eliminate the synchronization link in the circuit, avoiding measurement errors caused by inaccurate zero crossing in the synchronization link, thus achieving the goal of accurately calculating AC signals and improving measurement accuracy.

This standard meter can simultaneously measure various parameters such as three circuits, voltage, active power, reactive power, apparent power, power factor, total active power, total reactive power, total apparent power, total equivalent power factor, equivalent phase angle, and input frequency of the three-phase system. It can be read out at once through the RS232 interface and can also choose to output active or reactive energy pulses.

Due to the use of advanced technology, advanced processes, and advanced components, as well as the application of various compensation and data processing methods, this standard table has high accuracy, wide range, full functionality, stability, and reliability. In addition, the fully Chinese interface makes operation more convenient, making it an ideal power parameter measuring instrument.
