1. Introduction
The AT085 is a versatile digital display voltage, current, and power meter designed for testing various Type-C digital devices, power banks, and cell phone chargers. It features a high-definition color screen, real-time curve display, bidirectional current measurement, and support for multiple fast charging protocols. This manual provides detailed instructions for its setup, operation, and maintenance.
2. Key Features
- Real-time display of Voltage, Current, Power, Energy (Wh), Capacity (mAh), Temperature, and Timing.
- Real-time Voltage and Current Curve display for analyzing charging fluctuations.
- Support for multiple fast charging protocols (PD2.0, PD3.0, PPS, QC2.0, QC3.0, FCP, SCP, AFC, PE, DASH, VOOC, SuperVOOC).
- Bidirectional current measurement.
- Offline storage and power-off memory functions for data accumulation.
- Gravity-sensitive auto-rotating IPS high-definition colorful display.
- Zero power consumption when PD protocol charger has no current output, extending screen life.
- DC-DC switching power supply chip for wide input voltage range and high efficiency.
- One-touch zeroing of power capacity value.
- No-load current clearing function for accurate fine current measurement.
3. Setup and Connections
The AT085 features both C male and C female interfaces for flexible connection. It is designed for inline measurement between a power source and a device.
3.1 Interface Overview
- C male inputs and outputs: Connects to the power source (e.g., charger, power bank).
- C female inputs and outputs: Connects to the device being charged (e.g., phone, laptop).
- Down / Zero / Confirm key: Multi-function button for navigation, zeroing, and confirmation.
- Measurement data display area: The main screen showing all measurement parameters.
3.2 Connecting the Device
- Connect the C male end of the AT085 to your power source (e.g., USB-C charger, power bank's output port).
- Connect your device (e.g., smartphone, tablet, laptop) to the C female end of the AT085 using a compatible USB-C cable.
- Once connected, the AT085 display will automatically light up and begin showing real-time measurement data if current is flowing.
Note: The AT085 is designed with a zero-power consumption feature. If a PD protocol charger is connected but there is no load (no device drawing current), the display will not light up to save power. It will activate once a device is connected and drawing power.
4. Operating Instructions
4.1 Display Modes and Navigation
The AT085 offers multiple display interfaces to show various parameters. Use the 'Down / Zero / Confirm' key to navigate through these screens.
The main display shows:
- U: Current Voltage (V)
- I: Current Current (A)
- P: Current Power (W)
- E: Accumulated Energy (Wh)
- Additional information like recorded peak voltage, current, and power, or counting time and CPU temperature.
4.2 Real-time Curve Display
The AT085 can display real-time voltage and current curves, allowing users to observe fluctuations during charging. This feature can be paused and resumed by long-pressing the 'Down / Zero / Confirm' button.
4.3 Gravity Sensing and Screen Rotation
The device features an internal gravity acceleration sensor, allowing the display to automatically rotate to the positive direction for viewing, regardless of the device's orientation. You can lock the screen direction by performing a 5-stroke confirmation key sequence.
4.4 Data Clearing and Language Selection
- One-touch zeroing: Long press the confirmation button to clear the accumulated power capacity value.
- No-load current clearing: This function helps in making fine current measurements more accurate. Navigate to the appropriate screen and select 'No-load current clearing'.
- Language selection: The device supports English and Chinese display. Navigate to the language selection screen to choose your preferred language.
4.5 Peak Recording
The AT085 records the maximum voltage, current, and power values during the charging process. This allows users to easily check the peak charging power of their devices.
4.6 Internal Battery Capacity Calculation
The device can calculate the internal battery capacity based on the power quasi-value data during high-voltage charging. This calculation is performed through the software.
5. Maintenance
- Cleaning: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners or solvents.
- Storage: Store the AT085 in a cool, dry place away from direct sunlight and extreme temperatures.
- Power Saving: The device automatically turns off its screen when a PD protocol charger is connected without a load, contributing to extended screen life and energy efficiency.
- Avoid Impact: Protect the device from drops and impacts to prevent damage to the internal components and display.
6. Troubleshooting
- Q: Display does not light up when connected.
- A: Ensure both the power source and the device being charged are properly connected. If using a PD protocol charger, the display will only light up when a device is drawing current. Check if the power source is active and the cable is functional.
- Q: Readings appear inaccurate.
- A: Try using the 'No-load current clearing' function to recalibrate the current measurement. Ensure all connections are secure and clean. Test with a known good charger and device to verify.
- Q: Screen rotation is not working or is stuck.
- A: The gravity-sensing feature automatically rotates the screen. If it's stuck, you might have activated the screen lock. Perform the 5-stroke confirmation key sequence to unlock the screen direction.
- Q: Device is unresponsive.
- A: Disconnect the device from all power sources and connected devices, then reconnect. If the issue persists, ensure the working voltage (DC 4.5~50V) is within the specified range.

8. User Tips
- For precise current measurements, especially at low currents, utilize the 'No-load current clearing' function to zero out any residual readings.
- Take advantage of the real-time voltage and current curve display to monitor charging stability and identify any unusual fluctuations during the charging cycle.
- The power-off memory feature is useful for long-term testing of battery life, as it retains accumulated data even after the device is disconnected.
- Remember that the display will only activate when a device is actively drawing power from a PD protocol charger, which helps conserve the screen's lifespan.
