7. Operation
7.1 Mode Settings Overview
To enter the mode setting page, press and hold the on/off button for 2 seconds from the main display. To exit the settings page and return to the main page, press and hold the back setting button for 2 seconds.
The device offers the following modes:
- Mode 1: Lead acid P setting
- Mode 2: Ternary lithium L setting
- Mode 3: Iron Lithium F Setting
- Mode 4: Custom high and low voltage settings
- Mode 5: Low voltage alarm setting (alarm when voltage falls below this parameter)
- Mode 6: Backlight time setting
7.2 Battery Type Settings (Modes 1, 2, 3)
It is crucial to correctly identify your battery type (ternary lithium L or iron lithium F) before setting parameters. Fully charge your battery first. The saturation voltage for a series of ternary lithium batteries is DC4.2V, while for iron lithium batteries it is DC3.6V. For example, if a 7-string battery displays 29.4V when fully charged, it is a ternary lithium battery (7 strings x 4.2V = 29.4V).
Once the battery type is identified, proceed with the following steps:
- Lead-acid batteries (P setting): On the lead-acid battery setting page, the voltage parameter flashes. Short press the on/off button to select the battery voltage. After selecting, short press the setting button on the back to confirm and save the parameters. Long press the back button for 2 seconds to return to the main page, or short press to set other modes.
- Ternary lithium battery (L setting): On the ternary lithium battery setting page, the number of battery strings flashes. Short press the on/off button to select the number of battery strings. After selecting, short press the setting button on the back to confirm and save the number of strings. Long press the back button for 2 seconds to return to the main page, or short press to set other modes.
- Iron lithium battery (F setting): On the lithium iron battery setting page, the number of battery strings flashes. Short press the on/off button to select the number of battery strings. After selecting, short press the setting button on the back to confirm and save the number of strings. Long press the back button for 2 seconds to return to the main page, or short press to set other modes.
7.3 Custom High and Low Voltage Settings (Mode 4)
On the custom high and low voltage setting page:
- The left display shows the low voltage setting, and the right display shows the saturation voltage setting.
- Short press the on/off button to set the number on the left.
- After the value is set, long press the on/off button for 2 seconds to set the middle number.
- After the middle value is set, long press the on/off button for 2 seconds to set the right number.
- After the low voltage value is set, short press the back setting button to confirm and save the low voltage value.
- Then, short press the back setting button to switch to the saturation voltage setting page.
- After the saturation voltage value is set, short press the back setting button to confirm and save the value (all values are always on).
- Long press the back setting button for 2 seconds to return to the main page, or short press the back setting button to set other modes.
7.4 Low Voltage Alarm Settings (Mode 5)
On the low-voltage alarm setting page:
- The number on the left is the set value.
- Short press the ON/OFF button to set the middle number.
- After the middle value is set, press and hold the ON/OFF button for 2 seconds to set the right number.
- When the alarm voltage is set, short press the setting button on the back to confirm and save the value (all values are always on).
- Press and hold the setting button on the back for 2 seconds to return to the main page, or press the setting button on the back to set other modes.
7.5 Backlight Time Setting (Mode 6)

- Short press the back setting button to confirm and save the option.
- Long press the back setting button for 2 seconds to return to the main page, or short press the back setting button to perform other mode settings.
8. Voltage Smart Calibration
To calibrate the voltage of the meter, you need a high-precision DC30V power supply.
- Disconnect the power from the meter.
- Press and hold the on/off button.
- While holding the on/off button, turn on the power to enter calibration mode.
- Release the button.
- Press and hold the on/off button for 2 seconds to start automatic calibration.
During calibration, the letter 'V' will flash. After successful calibration, the letter 'V' will remain on.
Calibration Successful Display: The display will show '30.0V'.
Calibration Failure Display: The display will show 'Er'.
Note: If calibration fails (displays 'Er'), it indicates that the external power supply is too large or not a DC30V power supply. Please replace the external calibration power supply and re-calibrate.
9. Maintenance
- Keep the device clean and dry. Avoid exposure to moisture or corrosive substances.
- Do not attempt to disassemble or repair the device yourself, as this will void the warranty and may cause damage.
- Store the device in a cool, dry place when not in use.
10. Troubleshooting
- Device not powering on: Check the input voltage to ensure it is within the DC8-30V range and that connections are secure and correctly polarized.
- Inaccurate voltage readings: Perform a voltage smart calibration as described in Section 8. Ensure your calibration power supply is a stable DC30V.
- Calibration fails ('Er' display): Verify that the external power supply used for calibration is a high-precision DC30V source. Replace if necessary and retry calibration.
- Display issues (e.g., no backlight): Check backlight time settings in Mode 6.
11. User Tips
- For optimal accuracy, always ensure your battery is fully charged before attempting to set battery type parameters (Modes 1, 2, 3).
- When setting custom high and low voltages, double-check your desired values to prevent false alarms or incorrect readings.
- Utilize the USB and Type-C charging ports for convenient power delivery to compatible devices, but note that the working current specification (<15mA) applies when not actively charging.
12. Warranty and Support
For any issues not covered in this manual, please contact your retailer or the manufacturer's customer support. Keep your purchase receipt for warranty claims. Do not attempt to repair the device yourself, as this may void any applicable warranty.
