Technical Parameters
characteristic
The main function of the intelligent three-phase ammeter is to measure the three-phase current of the power grid. The three-row digital tube is displayed at the same time. It can be equipped with RS485 communication interface, transmission output (analog output), upper and lower limit alarm, and can directly set the current change on site. Than, it is very convenient to use.
Features and features:
1. Display magnification, communication address, baud rate, etc. can be set arbitrarily through the buttons on the panel, which is very flexible and convenient to use.
2. All can be equipped with 1 analog output, can choose the measured transmission output, the output is 4~20mA, 0~5V, 0~12~20mA, etc.
3. Optional relay alarm output, monitoring the upper and lower limits of the measured parameters.
4. It can be equipped with RS-485 digital interface and adopts standard MODBUS-RTU protocol.
5. Wide application range and strong combination function.
6. Digital zero calibration, digital calibration, high precision and high cost performance.
The accuracy level voltage and current meter are 0.5 and 0.2; the frequency meter is 0.1; the power and power factor meter is 0.5.

Precautions
1. Before use, the meter needs to be powered for 15 minutes.
2, pay attention to prevent vibration and shock, do not use in places with excessive dust and excessive harmful gases.
3. The input wire should not be too long. If the input end of the signal to be tested is long, please try the twisted pair shielded wire.
4. If the signal is accompanied by high frequency interference, the low frequency filter should be tested online.
5. When not storing for a long time, please power on every three months for not less than 4 hours.
6, long-term preservation should avoid direct light, should be stored in the ambient temperature -25 ° C ~ 55 ° C.
7. If the meter has no display, check the auxiliary power supply first, and the voltage is within the range.
8. If the display is not normal, check if the input signal is normal and the signal terminal is tight.
9. Unless the PT has sufficient power, the PT signal cannot be used as an auxiliary power source at the same time to ensure the normal operation of the meter.
10. The current terminal screw in the CT circuit must be tightened to ensure reliable contact between the incoming and outgoing wires to avoid malfunction.
11. If the instrument is to be calibrated, the calibration instrument should be better than 0.1 to ensure the calibration accuracy.
