This meter adopts an external independent high-precision adc, which brings high current and voltage accuracy. Inexpensive digital tube meter heads are either not calibrated, with large errors, or use small adjustable resistors. Rotating a little, the readings will change greatly and it is difficult to calibrate. Moreover, due to vibration and other reasons, the resistance of the adjustable resistor is not fixed, resulting in After a while, it was inaccurate again. However, this meter has no adjustable resistance, and it is completely adjusted and calibrated by buttons, so it has high accuracy and high stability.
    One advantage of this meter is the four-wire system. The digital tube meter head generally uses a three-wire system. The current pressure drop of the wire resistance causes a voltage error. The larger the current, the greater the voltage error. The four-wire system perfectly avoids this phenomenon.
   Another advantage of this meter is that the current is bidirectional. The current flowing from A+ to A- is a positive current, and the current flows in a reverse direction, which is a negative current, and the current displays-sign. The capacity statistics are automatically added or subtracted as the current direction changes.
  The meter head has 3 screens to display the content, the default display changes every 2 seconds, can be fixed to display any screen, you can save the display settings, please refer to the following instructions for use.
