Thiết lập và cài đặt

Proper wiring is crucial for accurate measurements and safe operation. The Hall sensor measures current by passing the load wire through its central hole. The display unit requires a power supply (DC 10-60V) and connects to the Hall sensor via the provided shielding wire.

Image: Three common wiring configurations for the meter, showing connections to battery, load, and optional relay.

Wiring Configuration 1: Basic Monitoring (Self-Powered)

In this configuration, the meter is powered directly from the battery being monitored. This is suitable for systems where the battery voltage is within the meter's operating range (10-60V).

1. Connect the positive terminal of the battery to the 'Bat+' terminal on the Hall sensor.
2. Connect the negative terminal of the battery to the 'Bat-' terminal on the Hall sensor.
3. Vượt qua tiêu cực load wire through the central hole of the Hall sensor. Ensure the direction of current flow through the sensor matches the arrow on the sensor for correct bidirectional readings.
4. Connect the display unit to the Hall sensor using the provided 50cm shielding wire.
5. Ensure the jumper cap on the Hall sensor is placed to select the self-powered mode (typically labeled '10-60V' or similar, check the sensor board for exact markings).

Wiring Configuration 2: External Power Supply

Use this configuration when the battery voltage is outside the meter's operating range (e.g., 0-10V or above 60V) or if you prefer a separate power source for the meter.

1. Connect the positive terminal of the battery to the 'Bat+' terminal on the Hall sensor.
2. Connect the negative terminal of the battery to the 'Bat-' terminal on the Hall sensor.
3. Vượt qua tiêu cực load wire through the central hole of the Hall sensor.
4. Connect the display unit to the Hall sensor using the provided 50cm shielding wire.
5. Connect an external DC power supply (10-60V) to the 'Vext+' and 'Vext-' terminals on the Hall sensor.
6. Remove the jumper cap from the Hall sensor to enable external power mode.

Wiring Configuration 3: With Relay for Output Control

This setup allows the meter to control an external relay (not included) based on configured protection parameters (e.g., over-current, low-voltagvà).

1. Follow either Configuration 1 or 2 for basic power and measurement connections.
2. Connect the relay's control terminals to the 'Relay+' and 'Relay-' terminals on the Hall sensor.
3. Ensure the jumper cap is set correctly for the chosen power mode (self-powered or external).
4. The meter's output control button can then be used to enable/disable the relay, or the relay can be triggered automatically by protection settings.

Hiển thị trênview

The 1.8-inch color LCD simultaneously displays:

• Tậptagđ(V): Top left, large font.
• Hiện tại (A): Below voltage, large font.
• Battery Capacity (%): Graphical bar and percentage.
• Amp-Hour (AH): Accumulated charge/discharge.
• Watt-Hour (WH): Accumulated energy.
• Công suất (W): Công suất tức thời.
• Time (H): Thời gian đã trôi qua.
• Chỉ số bảo vệ: OVP, OPP, OCP, OFT, OAH, LOP (Over-Voltage, Over-Power, Over-Current, Over-Time, Over-Charge, Low-Voltage Bảo vệ).

Chức năng nút

• Nút Mũi tên Lên: Navigates upwards through menu options or increases values during settings.
• Nút Mũi tên Xuống: Navigates downwards through menu options or decreases values during settings.
• Nút OK: Enters menu, confirms selections, or toggles display modes (e.g., battery graph). Press and hold to access certain functions or calibration mode.

Resetting AH and Time

To reset accumulated Amp-Hours (AH) and Time, navigate to the relevant display screen using the arrow buttons. Press and hold the OK button until the values reset. This is useful for monitoring specific charge/discharge cycles.

Quy trình hiệu chuẩn

For optimal accuracy, calibration may be required. Follow these steps carefully:

1. Vào chế độ hiệu chuẩn: While the device is powered off, press and hold the OK button. While holding OK, switch the power to the device ON. Release the OK button as soon as the display illuminates.
2. Navigation in Calibration Mode: In calibration mode, press the OK button to move from one menu item to the next. Use the Up Và Xuống arrow keys to adjust values.
3. Zero Current Calibration: Before calibrating current readings, ensure no current is flowing through the Hall sensor. Switch off all loads. Press OK until the "0.0 A" option is selected, then press the Xuống arrow once to zero out the current reading.
4. Positive Current Calibration (+A): To calibrate current in the charging direction, ensure current is flowing from the charging source into your battery. Press OK until the "+A" option is selected, then use the arrow keys to adjust the reading to match a known accurate current measurement.
5. Negative Current Calibration (-A): To calibrate current in the discharging direction, ensure current is flowing out of your battery into your loads. Press OK until the "-A" option is selected, then use the arrow keys to adjust the reading to match a known accurate current measurement.
6. Lưu cài đặt: After completing all calibrations, navigate the cursor to the "Save" option using the OK button. Select "Save" to store your settings.
7. Exit Calibration Mode: To exit calibration mode, simply switch the power to the unit OFF, then ON again.
