4. Setup
Before using the CellMeter 8, ensure you understand the connection points and button functions.
4.1 Device Overview
Image Description: A top-down view of the blue CellMeter 8 device. The LCD screen is prominent, displaying "CellMeter 8" and battery information. Below the screen are three buttons labeled "TYPE Setup Menu", "CELL Servo Test", and "MODE Discharge". A balance port is visible on the right side.
4.2 Connecting a Battery
- Lithium Batteries (LiPo, LiFe, Li-ion): Connect the balance plug of your battery to the 2-8S balance port on the right side of the CellMeter 8. Ensure the negative pin of the balance plug aligns with the negative indicator on the device. The device will automatically detect the cell count and display the voltage.
- NiCd/NiMH Batteries: Connect the discharge plug of your NiCd/NiMH battery to the dedicated NiCd/NiMH port on the device.
Image Description: The CellMeter 8 is shown connected to a large HRB 5000mAh LiPo battery. The device's screen displays "11.58V" and "Total 51%", indicating the battery's current voltage and remaining capacity. The balance lead of the battery is plugged into the side of the CellMeter 8.
4.3 Connecting a Servo for Testing
To test a servo, connect it to the servo test port on the CellMeter 8. The servo test range can be set between 1000-2000us or 500-2500us.
5. Operating Instructions
The CellMeter 8 features three buttons: TYPE, CELL, and MODE. These buttons allow you to navigate through different functions and display modes.
5.1 Battery Checking Functions
- Power On: Connect a battery to the appropriate port. The device will power on automatically and display the total voltage and remaining capacity.
- Changing Battery Type (TYPE button):
- Press the TYPE button repeatedly to cycle through supported battery types (LiPo, LiFe, Li-ion). Ensure the displayed type matches your connected battery for accurate readings.
- Viewing Cell Voltages (CELL button):
- Press the CELL button repeatedly to view the voltage of each individual cell in your lithium battery pack. The display will cycle through Cell 1, Cell 2, and so on, up to the maximum cell count.
- The display will also show the highest cell voltage, lowest cell voltage, and the voltage difference between them.
- Balance Discharge (MODE button):
- When a lithium battery is connected, press and hold the MODE button to initiate the balance discharge function. This will slowly discharge the higher voltage cells to match the lower ones, improving battery balance.
- The discharge current is 1A. Monitor the process and disconnect the battery when balancing is complete or if you need to stop.
Image Description: A close-up of the CellMeter 8's backlit LCD screen. It displays "LiPo 1S 2S 3S" at the top, "11.72V" as the total voltage, and "Total 61%" for the remaining capacity. The balance port pins are visible on the right.
5.2 Servo Testing Function
- Enter Servo Test Mode: Connect a servo to the servo test port. Press the CELL button (labeled "Servo Test") to enter servo testing mode.
- Adjust Servo Parameters: Use the TYPE and MODE buttons to adjust the servo test parameters, such as pulse width (1000-2000us or 500-2500us) or test mode (manual adjustment, automatic, neutral).
- Observe Servo Movement: The servo will move according to the set parameters, allowing you to verify its functionality.
6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the device. Do not use liquid cleaners or solvents.
- Storage: Store the CellMeter 8 in a cool, dry place away from direct sunlight and extreme temperatures.
- Handling: Avoid dropping the device or subjecting it to strong impacts.
- Connections: Always ensure battery and servo connections are secure and correctly polarized to prevent damage to the device or components.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Battery not connected or connected incorrectly. Battery voltage too low. | Ensure the battery is properly connected to the correct port. Check if the battery has sufficient charge. |
| Incorrect battery type displayed. | Device auto-detection error or wrong manual selection. | Press the TYPE button to manually select the correct battery type (LiPo, LiFe, Li-ion). |
| Inaccurate voltage readings. | Poor connection. Damaged balance lead. | Ensure all connections are secure. Inspect battery balance leads for damage. |
| Servo not responding during test. | Servo connected incorrectly. Faulty servo. | Verify servo connection to the correct port and polarity. Test with a known working servo. |
