Safety Instructions

To avoid potential electric shock, fire hazards, and personal injury, please read the safety precautions before use. Only use the product for its intended purpose, as misuse may compromise the protection provided by the product.

• Before using the product, please check the casing for any cracks or plastic damage. Carefully inspect the insulator near the input ports.
• Please follow this user manual to use the correct input ports and settings, and perform measurements within the specified range outlined in this manual.
• Do not use this product in the presence of explosive gases and vapors or in humid environments.
• Keep your fingers behind the protective device of the test probes or tips.
• Do not touch unused input ports when the product is connected to the circuit under test.
• Before changing the test setting, disconnect the test probes from the circuit. When the direct current voltage is above 36V or the alternating current voltage is above 30V, it may pose a serious risk of injury to the user; therefore, precautions should be taken to avoid electric shock.
• Please select the correct test setting and range to avoid damage to the instrument or personal injury.
• Do not use this product with the front or back cover open.
• When the battery voltage is too low, it may affect the accuracy of the test results; please recharge it in a timely manner.
• The ground connection between the two channels is the same; during measurement, the ground clips should always be grounded or connected at the same potential.
• The probe ground is at the same potential as the ground. When connecting the USB cable for charging, the probe ground must not be clipped to high voltage; otherwise, it may damage the product or cause injury to the user.
• When using the oscilloscope probe to measure voltages above (AC 30V or DC 36V), please ensure that the USB protection cover of the product is securely closed to avoid human contact with exposed metal parts; otherwise, there is a risk of personal injury.

Product Overview Video

This video provides a visual overview of the BTMETER BT-50M's features and basic operation.

Probe Inspection

Before connecting probes, always perform a visual inspection and compensation check.

Safety

When using the probe, to avoid electric shock, keep your fingers behind the safety ring on the probe body. Do not touch the metal part at the top of the probe when it is connected to a high-voltage power source. The measured voltage must not exceed the probe's specifications (maximum 150V for 1X setting and 300V for 10X setting; otherwise, it may damage the instrument).

Manual Probe Compensation

1. When connecting the probe to the oscilloscope for the first time, it is recommended to perform the following compensation check. Probes that are not compensated or have compensation deviations can lead to measurement errors or inaccuracies.
2. After powering on, connect the probe to the signal input terminal and input a 3V/1kHz square wave signal.

Once connected, press the AUTO button on the panel to check the waveform display status. The display should show a 'Compensation Normal' waveform. If not, adjust the capacitance on the probe using the provided adjustment tool until the waveform is correct.

Probe Attenuation Settings

The probe attenuation coefficient setting will affect the vertical scale readings of the signal. Ensure that the attenuation switch multiplier on the probe matches the probe attenuation multiplier option in the oscilloscope system settings. If the switch is set to X1, the oscilloscope should also be set to X1; if the switch is set to X10, the oscilloscope should be set to X10.

Note: When the probe is set to X1, a probe rated at 10MHz/X1 will limit the oscilloscope's bandwidth to 10MHz input. To utilize the full bandwidth of the oscilloscope, ensure the switch is set to X10 or use a probe with a higher specification.

Baseline Correction

The instrument is 100% calibrated before leaving the factory, but if there is a baseline zero offset phenomenon found in situations such as large environmental temperature deviation or long-term disuse, baseline calibration can be performed.

1. Select the "Baseline Calibration" mode from the System Function Menu Settings.
2. After unplugging the probe as prompted on the screen, briefly press the "MENU" button to start calibration.

Important during calibration:

• Do not connect the probe and input signal during calibration, otherwise it may cause calibration deviation or damage to the instrument.
• Do not perform any other operations during the calibration process; wait patiently until the calibration is completed.

Battery Charging

When the battery level symbol appears in the upper right corner of the screen, charge the battery promptly as follows:

1. Open the "USB" cover and insert the TYPE-C data cable.
2. Connect the TYPE-C cable to a DC5V output adapter or a computer USB port for charging.
3. While charging, the screen displays the charging symbol, and the built-in red light of the power button "REL/" will light up.
4. When fully charged, the screen displays the full battery symbol, and the built-in red light of the power button "REL/" will turn off.

5. Troubleshooting

This section provides general guidance for common issues. For more complex problems, please contact support.

• Device not powering on: Ensure the battery is charged. Connect to a power source via USB-C. If still unresponsive, check for physical damage or try a hard reset (if applicable, consult the full PDF manual).
• Inaccurate readings: Perform probe compensation (see Setup section). Check probe attenuation settings match the device. Ensure proper connection of test leads. Calibrate the device if environmental conditions have changed significantly or after long disuse (see Baseline Correction in Setup).
• No waveform display: Check if the channel is enabled. Verify trigger settings (mode, level, source). Ensure probes are correctly connected to the signal source and the device. Adjust vertical and horizontal scales.
• Signal Generator output issues: Verify the output waveform type, amplitude, frequency, and duty cycle settings. Ensure the output is enabled.
• Multimeter not measuring: Check test lead connections to the correct input terminals (COM, VΩHz, mA, 10A). Ensure the correct measurement function is selected. Verify the circuit under test is powered (for voltage/current) or unpowered (for resistance/capacitance).
• Device freezing or unresponsive: Try restarting the device by long-pressing the power key. If persistent, check for firmware updates (consult the full PDF manual).
