Thank you for choosing the digital display meters researched and produced by
Jiangsu Sfere Electric Co., Ltd. Please read this manual carefully and follow the
instructions strictly to ensure your safe, correct and efficient purchase and use of the
product.
◆Make sure only the qualified technicians perform the installation and maintenance;
◆Before performing wiring operation to the meter, make sure the input signal and
the power supply are switched off;
◆The proper voltage detecting device should be used to guarantee no voltage in any
part of the meter;
◆The electrical parameters supplied to the meter should be within the rated range;
The following situations may result in damages to the meter or cause mistakes in the
operation of the meter.
◆The voltage of the auxiliary power supply goes beyond the rated range.
◆The frequency of the power distribution system goes beyond the rated range.
◆The input polarity of the voltage or the current is incorrect.
◆Remove or connect the communication plugs without powering off.
◆Connect the terminal wires against the related instructions.
Please don’t touch the terminals when the meter is in operation!

1. Function Description
Digital display ammeters measure three phase or single phase current parameters of grid by
adopting AC sampling technology. This series of meters support RS-485 communication interface
(Modbus-RTU protocol), analog output, digital input and relay output function. The transmission
ratio can be changed through the operation buttons on the panel of meter.
