5.1 Wiring the Module
The WEL3005 module requires careful wiring to ensure proper operation and accurate measurements. Refer to the diagram below for correct connections.
- वीज पुरवठा: Connect a 6V-30V DC power source to the module's supply input.
- लोड कनेक्शन:
- Connect the positive terminal of the device under test (e.g., battery) to the "B+" terminal for current measurement.
- Connect the negative terminal of the device under test to the "B-" terminal for current measurement.
- व्हॉल्यूमची खात्री कराtage measurement leads are connected to the appropriate B+ and B- terminals for voltagई संवेदना.
- The module features input anti-reverse protection, but always double-check polarity before powering on.
५.१ प्रारंभिक पॉवर-अप
- After wiring, turn on the module using the rotary encoder.
- The color display will illuminate, showing current readings and status.
- The fan will automatically start if the internal temperature exceeds 45°C.
6. ऑपरेटिंग सूचना
6.1 Adjusting Discharge Current
- Use the rotary encoder to continuously adjust the discharge current from 0A to 5A.
- Rotate clockwise to increase current, counter-clockwise to decrease.
- Observe the display for real-time current values.
४.४ देखरेख पॅरामीटर्स
The color display shows the following parameters:
- खंडtage (U)
- वर्तमान (I)
- पॉवर (पी)
- क्षमता (Ah)
- ऊर्जा (Wh)
- प्रतिकार (R)
- तापमान (T)
6.3 संरक्षण कार्ये
The module is equipped with several protection features:
- अंडरव्होलtagई संरक्षण: Activates if the voltage drops below the set threshold (1.5-30V).
- Over Power Protection: Engages if the discharge power exceeds the set limit (1-30W).
- अतिउष्णतेपासून संरक्षण: The fan starts at 45°C, and protection activates if the temperature reaches 75°C.
6.4 Setting Menu (SET Button)
Press the SET button to enter the configuration menu. Use the rotary encoder to navigate and adjust settings such as undervoltage limits and overpower limits. Press SET again to confirm changes or exit the menu.
6.5 Internal Resistance Measurement (LOCK Button)
Use the LOCK button for specific internal resistance measurement functions. Refer to the on-screen prompts or detailed operational guides for this advanced feature.
7. देखभाल
