4. 설정 지침
Follow these steps to properly connect your KWS-DC26 DC Power Meter:
- 터미널 식별: The meter has clear input and output terminals, typically marked for positive (+) and negative (-) connections. Ensure you connect the power source to the input and the load to the output.
- 전원 연결: Connect the positive terminal of your DC power source (e.g., battery, solar panel) to the positive input terminal of the meter. Connect the negative terminal of the power source to the negative input terminal of the meter.
- 연결 부하: Connect the positive terminal of your DC load (e.g., electric vehicle, device under test) to the positive output terminal of the meter. Connect the negative terminal of the load to the negative output terminal of the meter.
- Ensure Correct Polarity: Double-check all connections to ensure correct polarity. Incorrect polarity can damage the device or the connected equipment.
- Connect Thermostat (Optional): If real-time temperature monitoring is desired, connect the provided thermostat probe to the designated port on the meter. Position the probe to monitor the temperature of the product or environment you wish to measure.
The KWS-DC26 is compatible with various devices and connector types. Ensure the connector type matches your application's current requirements (e.g., 3 pins 20A, XT60 25A, XT90 35A, Anderson 50A).
5. 사용 설명서
Once properly connected, the KWS-DC26 meter will automatically power on and begin displaying measurements.
5.1 디스플레이 오버view
The color LCD displays various parameters simultaneously:
- 권tag전자(V): 현재 DC 볼륨tage.
- 전류(A): 현재 DC amperage. Arrows indicate direction (charge/discharge).
- 전력(W): Instantaneous power consumption/generation.
- 에너지(Wh): Accumulated energy in Watt-hours.
- 용량(Ah): Accumulated charge/discharge capacity in Amp영업시간 전.
- 시간제 노동자: 측정에 소요된 시간.
- 온도(°C): Real-time temperature from the connected thermostat.
5.2 Bidirectional Measurement
The meter automatically detects the direction of current flow. Arrows on the display will indicate whether current is flowing into (charging) or out of (discharging) the connected battery or system.
5.3 알람
The KWS-DC26 includes alarm indicators for:
- 오버볼tage: Alerts if the voltage는 안전 한계를 초과합니다.
- 과전류: Alerts if the current exceeds a safe limit.
- 과열: Alerts if the monitored temperature exceeds a safe limit.
When an alarm triggers, the corresponding indicator on the display will activate. Address the cause of the alarm immediately to prevent damage to the meter or connected equipment.
5.4 Data Logging and Memory
The meter continuously logs energy (Wh) and capacity (Ah) data. In case of power loss, the built-in power failure memory ensures that accumulated data is retained. The timer function tracks the duration of the measurement session.
5.5 데이터 지우기
The meter features a 'Time clear' function, which typically allows you to reset the accumulated energy (Wh), capacity (Ah), and timer data. Refer to the device's physical buttons or on-screen menu (if applicable) for specific instructions on how to perform a data clear.
6. 유지관리
To ensure the longevity and accurate performance of your KWS-DC26 DC Power Meter, follow these maintenance guidelines:
- 청소: 부드럽고 마른 천을 사용하여 기기를 닦으세요. 연마성 세제나 용제는 사용하지 마세요.
- 저장: 측정기는 직사광선과 극한의 온도를 피해 서늘하고 건조한 곳에 보관하세요.
