3. Setup

3.1 Battery Installation

Both the TCM-300D and TSM-192 require AAA batteries for operation.

1. Locate the battery compartment on the back of the device.
2. Use a screwdriver (if necessary) to open the battery cover.
3. Insert the AAA batteries, ensuring correct polarity (+/-).
4. Securely close the battery cover.

Note: Ensure batteries are installed correctly to prevent damage to the device.

4. Operating Instructions: TESMEN TCM-300D Clamp Meter

4.1 General Operation

The TCM-300D features an intelligent auto mode that automatically detects the measurement type (voltage, resistance, continuity) when test leads are connected. For specific functions, use the FUNC/AUTO button.

4.2 AC/DC Current Measurement (Clamp Function)

1. Power on the TCM-300D.
2. Ensure the device is in AC/DC current mode (or Auto mode will detect it).
3. Open the clamp jaws by pressing the trigger.
4. Enclose a single conductor (not a power cord with multiple wires) within the clamp jaws.
5. Read the current value on the display.

4.3 Inrush Current Measurement

1. Select the Inrush function using the SEL/INRUSH button.
2. Clamp the meter around the conductor of the device to be tested.
3. Activate the device. The meter will capture the peak inrush current.

4.4 Voltage, Resistance, Continuity, Diode, Capacitance, Frequency, Temperature (using Test Leads)

1. Insert the red test lead into the VΩHz input jack and the black test lead into the COM input jack.
2. Power on the TCM-300D.
3. Use the FUNC/AUTO button to cycle through the desired measurement mode (Voltage, Resistance, Continuity, Diode, Capacitance, Frequency, Temperature).
4. Connect the test leads to the circuit or component under test.
5. Read the measurement on the display.

4.5 Non-Contact Voltage (NCV)

1. Select NCV mode.
2. Bring the NCV sensor (top of the clamp meter) close to the conductor.
3. The meter will indicate the presence of AC voltage with an audible beep and visual indicator.

5. Operating Instructions: TESMEN TSM-192 Digital Multimeter

5.1 General Operation (Smart Auto Mode)

The TSM-192 features a smart automatic mode that simplifies measurements by automatically identifying the input signal (AC/DC voltage, resistance, continuity).

1. Insert the red test lead into the INPUT jack and the black test lead into the COM jack.
2. Power on the TSM-192. The device will enter smart auto mode.
3. Connect the test leads to the circuit or component. The meter will automatically display the relevant measurement.

6. Maintenance

6.1 Cleaning

• Disconnect the devices from all circuits and power sources before cleaning.
• Wipe the casing with a damp cloth and mild detergent. Do not use abrasives or solvents.
• Ensure the devices are completely dry before storage or next use.

6.2 Storage

• If the devices will not be used for an extended period, remove the batteries to prevent leakage.
• Store the devices and accessories in their provided storage bags in a cool, dry place, away from direct sunlight and extreme temperatures.

7. Troubleshooting

7.1 Common Issues and Solutions

• No Display/Power On: Check battery installation and ensure batteries are not depleted. Replace if necessary.
• Inaccurate Readings: Ensure test leads are properly connected and not damaged. Verify the correct measurement function is selected. Clean contact points.
• "OL" or "OVERLOAD" on Display: The measured value exceeds the device's range for the selected function. Select a higher range or a different measurement method if available.
• No NCV Detection: Ensure NCV mode is active and the sensor is close enough to the AC voltage source.

If issues persist, contact TESMEN customer support.
