Description: 1. The display of current and voltage is applicable to various types of batteries. 2.6-in-1 multifunction - the current and voltage detects and displays voltage, current, active power supply, battery energy, power frequency and power factor on one interface. 3. Memory function: in case of power failure, during the use of the instrument, the cumulative value of the electric energy of the instrument will be saved by itself (the previous electric energy data will be saved). 4. Safety for protection - the current and voltage is designed with input reverse connection for protection, short circuit for protection, overheating for protection, overcurrent for protection, overvoltage for protection and undervoltage for protection. 5. Current and voltage display screen – digital LCD color display.

Power frequency: 45.0hz-65.0hz 7 Measuring speed: 2 times / S 8 matters needing attention: 1. The voltage input (green) terminal and the current transformer secondary input (blue) terminal shall not be connected incorrectly, otherwise the instrument will be damaged! 2. This instrument is only applicable to pure AC 50-60Hz mains power supply, and cannot be used for measurement on square wave, inverter output and corrected positive and negative wave circuit, otherwise the instrument will be damaged! 3 during the installation of the instrument, remember not to squeeze the instrument LCD, otherwise there will be code confusion / code breaking.
