Structural features: The measured signal is shaped by a transmitter, integrated by a logic operation circuit, and then displayed by LED digital display. The product features are as follows: 1. Internally, voltage transformers and current transformers are used to isolate the input signal, making the instrument have high overload capacity. 2. The display is intuitive, accurate, and clear; 3. Good linearity; 4. Small error and low power consumption; 5. Easy to achieve telemetry and remote control.

Usage precautions:
1. This instrument is a precision measuring instrument that should be protected from strong vibration and impact during installation and use, as well as from corrosive gases or dust.
When the instrument displays 0 and IL, it indicates that there is no current input. 3. When the instrument is 0 and FAN, it indicates that the current direction is reversed or Ua and Uc voltages are not input or Ua and Uc voltage phases are connected incorrectly.
