Дастурҳои амалиётӣ
Display Readings:
The DDS661 meter features an LCD backlight display that cycles through various parameters or can be manually advanced depending on the model. Common display parameters include:
- кВт/соат: Total active energy consumption.
- Ҷилдиtagд (V): Instantaneous line voltage.
- ҷорӣ (A): Instantaneous line current.
- Қувваи (Вт): Instantaneous active power.
- Омили нерӯ (PF): The ratio of real power to apparent power.
- Фосила (Гц): The frequency of the AC supply.
The green LED indicator flashes at a rate of 1000 imp/kWh, indicating active energy measurement. A faster flash rate signifies higher power consumption.
RS485 Communication (for DDS661-RS485 models):
For models equipped with RS485, the meter can be integrated into a monitoring system for remote data acquisition. Refer to the specific RS485 communication protocol documentation for details on data registers, baud rates, and addressing. This functionality allows for convenient management and monitoring of power status.
Нигоҳдорӣ
The NENEN DDS661 energy meter is designed for long-term, maintenance-free operation under normal conditions. Regular checks are recommended:
- Тозакунӣ: Ҳисобкунакро тоза ва аз чанг озод нигоҳ доред. Барои тоза кардан аз матои мулоим ва хушк истифода баред. Аз тозакунандаҳои абразивӣ ё ҳалкунандаҳо истифода набаред.
- Санҷишҳои пайвастшавӣ: Periodically inspect wiring connections to ensure they remain tight and free from corrosion.
- Шароити экологӣ: Боварӣ ҳосил кунед, ки муҳити корӣ дар ҳудуди муқарраршудаи ҳарорат ва намӣ боқӣ мемонад.
Мушкилкушо
| Мушкилот | Сабаби эҳтимолӣ | Ҳалли |
|---|---|---|
| Meter display is blank. | No power supply; incorrect wiring; internal fault. | Check power supply to the circuit. Verify wiring connections. If power is present and wiring is correct, the meter may be faulty and require replacement. |
| KWh reading not increasing. | No load connected; incorrect wiring; internal fault. | Ensure a load is connected and drawing power. Verify wiring, especially input/output terminals. If issues persist, the meter may be faulty. |
| Green LED not flashing. | No power consumption; LED fault. | Confirm that there is active power consumption. If power is being consumed and the LED does not flash, there might be an internal issue. |
| Хониши нодуруст. | Incorrect wiring; external interference; meter calibration issue. | Re-check all wiring connections. Ensure the meter is not exposed to strong electromagnetic fields. If suspected calibration issues, contact support. |
