The BT-570C-APP requires one 9V (6F22) battery (not included). To install or replace the battery:

1. Ensure the meter is turned OFF.
2. Locate the battery compartment on the back of the meter.
3. Use a screwdriver to open the battery compartment cover.
4. Insert the 9V battery, observing the correct polarity.
5. Close the battery compartment cover and secure it with the screw.

5.2. Test Lead Connection

Proper connection of test leads is crucial for accurate and safe measurements.

Video Description: This video demonstrates how to properly insert and test the leads, check for continuity, perform capacitance and resistance tests, measure battery voltage, and connect to the mobile app.

To connect the test leads:

1. Insert the black test lead into the "COM" (Common) terminal.
2. Insert the red test lead into the "T+VΩHz" terminal for most measurements (voltage, resistance, capacitance, frequency, temperature).
3. Ensure the test leads and the interface are fully connected to prevent loose connections and inaccurate readings.

5.3. Mobile APP Connection (Bluetooth)

The BT-570C-APP can connect to a mobile application for data recording, analysis, and remote monitoring (within 10-15m).

Steps for APP Connection:

1. Find the QR code on the manual (or product packaging) and scan it with your smartphone to download the "Ailink APP" or "INTELLIGENT CLAMP METER" app.
2. Open the Ailink APP, register a new account, and log in.
3. In the app, navigate to the device connection section and press "Add" to connect the phone.
4. Ensure your clamp meter is powered on and Bluetooth is enabled on your phone.
5. The app will prompt you to allow Bluetooth connection. Confirm to connect your device.
6. Once connected, the measured data from the clamp meter can be stored in the mobile phone and consulted at any time.

6. Operating Instructions

6.1. General Operation

• Power On/Off: Turn the Rotary Switch from "OFF" to the desired measurement function to power on. Turn back to "OFF" to power off.
• Backlight: Long press the "HOLD" button for more than 2 seconds to turn on/off the screen backlight.
• Data Hold: Press the "HOLD" button briefly to freeze the current reading on the display. Press again to release.
• Auto/Manual Ranging: The meter defaults to auto-ranging. Press the "RANGE" key to switch to manual ranging. Long press "RANGE" to return to auto-ranging.
• MAX/MIN Value: Press the "MAX/MIN" key to capture the maximum or minimum reading during a measurement. Long press to exit.
• Zero Read Reset: When performing certain measurements (e.g., current), you may need to zero the reading. Press the "REL" key to reset the reading on the screen to zero.

6.2. Specific Measurement Modes

Always ensure the test leads are correctly inserted and the rotary switch is set to the appropriate function before making any measurement.

6.2.1. Voltage Measurement (AC/DC)

1. Turn the Rotary Switch to the "V~" (AC Voltage) or "V=" (DC Voltage) position.
2. Connect the test leads to the circuit or component you wish to measure.
3. Read the voltage value on the LCD display.

6.2.2. Current Measurement (AC/DC Clamp)

For current measurement, use the clamp jaws. It is critical to clamp around a single conductor, not an entire power cord.

Current Measurement Examples: The images illustrate how to measure 10 Ohm Resistance, 100uF Capacitance, 220V AC Voltage, 1000V DC/AC Voltage, 100V DC Current, and 1000V DC Current.

1. Turn the Rotary Switch to the "200A", "400A", or "1000A" (AC/DC Current) position.
2. Open the clamp jaws using the jaw-opening handle.
3. Enclose a single conductor (not a power cord with multiple wires) within the jaws.
4. Close the jaws and read the current value on the LCD display.

Important: For accurate current measurement with the clamp, ensure only one wire is placed inside the clamp jaws. Clamping around a power cord containing both live and neutral wires will result in a zero reading as the magnetic fields cancel each other out.

6.2.3. Resistance Measurement

1. Turn the Rotary Switch to the "ΩCAPHz" position.
2. Press the "SELECT" key until the "Ω" symbol is displayed.
3. Connect the test leads across the component you wish to measure.
4. Read the resistance value on the LCD display.

6.2.4. Continuity Test

1. Turn the Rotary Switch to the "ΩCAPHz" position.
2. Press the "SELECT" key until the continuity symbol (a speaker icon) is displayed.
3. Connect the test leads across the component or circuit.
4. If the resistance is less than 100Ω, the built-in buzzer will sound, indicating continuity.

6.2.5. Capacitance Test

1. Turn the Rotary Switch to the "ΩCAPHz" position.
2. Press the "SELECT" key until the capacitance symbol (nF, uF) is displayed.
3. Connect the test leads across the capacitor.
4. Read the capacitance value on the LCD display.

6.2.6. Diode Test

1. Turn the Rotary Switch to the "ΩCAPHz" position.
2. Press the "SELECT" key until the diode symbol is displayed.
3. Connect the red test lead to the anode and the black test lead to the cathode of the diode.
4. Read the forward voltage drop on the LCD display. Reverse the leads to check for open circuit (OL).

6.2.7. Frequency and Duty Cycle Measurement

1. Turn the Rotary Switch to the "Hz" position (or ACV/ACA range).
2. Press the "Hz/Duty" key to toggle between frequency (Hz) and duty cycle (%) measurements.
3. Connect the test leads to the signal source.
4. Read the frequency or duty cycle value on the LCD display.

6.2.8. Temperature Measurement

The clamp meter is equipped with a thermocouple for temperature measurement.

Temperature Measurement: The image shows the meter measuring temperature in Celsius. The display can be switched between Celsius and Fahrenheit.

1. Turn the Rotary Switch to the "℃/℉" position.
2. Insert the temperature probe (thermocouple) into the "COM" and "T+VΩHz" terminals.
3. Place the tip of the probe on or in the object whose temperature you wish to measure.
4. Read the temperature value on the LCD display. You can switch between Celsius and Fahrenheit using the "SELECT" key if available in this mode.

7. Maintenance

7.1. Cleaning

• Wipe the meter with a dry, soft cloth. Do not use abrasives or solvents.
• Keep the meter dry.

7.2. Battery Replacement

When the low battery indicator appears on the display, replace the 9V battery as described in the "Battery Installation" section (5.1).

7.3. Fuse Replacement

The device features a double fuse for overload protection on all ranges.

If the meter fails to function correctly, and you suspect a blown fuse, contact customer support for assistance. Do not attempt to replace fuses yourself unless you are qualified to do so, as it may void the warranty or cause further damage.

8. Troubleshooting

If you encounter issues with your BT-570C-APP, try the following:

• No Display/Faint Display: Check battery level and replace if necessary. Ensure the meter is powered on.
• Incorrect Readings: Verify test lead connections are secure and inserted into the correct terminals. Ensure the rotary switch is set to the appropriate function and range. Check for external interference.
• No Continuity Beep: Ensure the continuity function is selected and test leads are properly connected. The resistance must be less than 100Ω for the buzzer to sound.
• App Connection Issues: Ensure Bluetooth is enabled on both the meter and your smartphone. Restart both devices. Make sure the app is up to date.
• "OL" on Display: This indicates an overload or out-of-range measurement. Select a higher range or ensure the measured value is within the meter's capabilities.

For persistent issues, please refer to the Warranty/Support section.

9. User Tips

• For current measurements, always isolate the single wire you intend to measure from the bundle to ensure accurate readings with the clamp jaws.
• Utilize the data hold function ("HOLD" button) when taking measurements in hard-to-reach or poorly lit areas to record the reading after removing the meter.
• The mobile app is very useful for logging data over time or for remote monitoring, especially in situations where direct viewing of the meter display is inconvenient.
• Remember to turn off the meter when not in use to conserve battery life.
