5. Setup

5.1. Charging the Battery

The BSIDE U1 is powered by a built-in 3.7V rechargeable Li-ion battery. Before first use, or when the low battery indicator appears, charge the device using the provided USB charging cable.

1. Connect the small end of the USB charging cable to the charging port on the multimeter.
2. Connect the standard USB end to a USB power adapter (not supplied) or a computer USB port.
3. The display will indicate charging status. Ensure the device is fully charged for optimal performance.

5.2. Connecting Test Leads

For voltage, resistance, continuity, capacitance, diode, and frequency measurements, connect the test leads to the input jacks.

• Insert the black test lead into the 'COM' (common) jack.
• Insert the red test lead into the 'INPUT' jack.

6. Operating Modes and Measurements

The BSIDE U1 features automatic measurement for common parameters upon power-on. Manual mode allows selection of specific functions.

6.1. Power On/Off

Press and hold the power button (U) to turn the device on or off. The device will automatically enter auto-ranging mode upon startup.

6.2. Automatic Measurement Mode

When powered on, the multimeter automatically detects and measures AC/DC voltage, resistance, and continuity. Simply connect the test leads to the circuit or component, and the device will display the appropriate reading.

6.3. Manual Mode Selection

Press the 'AUTO' button to cycle through manual measurement functions. The selected function will be indicated on the display.

6.4. AC/DC Voltage Measurement

1. Ensure test leads are connected correctly (black to COM, red to INPUT).
2. Select Voltage mode (if not in auto-ranging).
3. Connect the test leads in parallel across the component or circuit to measure voltage.

6.5. AC/DC Current Measurement (Open Jaw Clamp)

The open jaw clamp allows for non-contact AC or DC current measurement. For DC current, a zeroing step is required.

1. Select Current mode.
2. For DC current, press the 'ZERO' button to zero the reading before measurement.
3. Place the open jaw around a single conductor (not a cable containing multiple conductors) through which the current flows.
4. Read the current value on the display.

6.6. Resistance Measurement

1. Ensure the circuit or component is de-energized.
2. Select Resistance mode.
3. Connect the test leads across the component to measure its resistance.

6.7. Continuity Test

1. Ensure the circuit or component is de-energized.
2. Select Continuity mode.
3. Connect the test leads across the circuit or component. A continuous beep indicates continuity (low resistance).

6.8. Capacitance Measurement

1. Ensure the capacitor is discharged before testing.
2. Select Capacitance mode.
3. Connect the test leads across the capacitor terminals.

6.9. Diode Test

1. Ensure the diode is disconnected from the circuit.
2. Select Diode mode.
3. Connect the red test lead to the anode and the black test lead to the cathode. The forward voltage drop will be displayed. Reverse the leads to check for open circuit.

6.10. Frequency Measurement

1. Select Frequency mode.
2. Connect the test leads to the signal source.

6.11. NCV (Non-Contact Voltage) Detection

The NCV function allows for quick detection of AC voltage without direct contact.

1. Select NCV mode.
2. Bring the tip of the multimeter near the conductor. The device will beep and the display will indicate the presence of AC voltage.

6.12. Live Wire Detection

This function helps identify live wires using a single test lead.

1. Select Live Wire mode.
2. Insert the red test lead into the 'INPUT' jack.
3. Touch the tip of the red test lead to the conductor. The device will indicate if the wire is live.

6.13. Ambient Temperature Measurement

The device can measure ambient temperature.

1. Select Temperature mode.
2. The ambient temperature will be displayed. Note: External thermocouples for contact temperature measurement are not supplied.

7. Maintenance

7.1. Cleaning

Wipe the device with a dry, soft cloth. Do not use abrasive cleaners or solvents. Ensure the device is off and disconnected from any power source before cleaning.

7.2. Battery Care

The integrated Li-ion battery should be charged regularly, especially if the device is not used for extended periods, to maintain battery health. Avoid extreme temperatures during storage.

7.3. Storage

Store the multimeter in its carrying case in a cool, dry place, away from direct sunlight and extreme temperatures. Remove test leads before storing.

8. Troubleshooting

• Device does not power on: Ensure the battery is charged. Connect the USB charging cable and try again.
• Inaccurate readings: Check test lead connections. Ensure the correct measurement mode is selected. For DC current, perform a zeroing operation.
• No continuity beep: Ensure the circuit is de-energized. Check for open circuits or high resistance.
• NCV not detecting voltage: Ensure the NCV sensor is close enough to the conductor. Verify the conductor is live.
