3.2 Test Leads
The test leads for the TSM-192 are permanently connected to the device for convenience and to prevent loss. Ensure they are not damaged before use.
4. Operating Instructions
4.1 Smart Automatic Mode
The TSM-192 features a smart automatic mode that simplifies operation. When powered on, the multimeter automatically detects the type of measurement (voltage, resistance, continuity) and selects the appropriate range. This eliminates the need for manual mode selection for common measurements.

4.2 Measurement Functions
While in Smart Auto Mode, the multimeter can perform the following measurements:
- AC/DC Voltage: Measures alternating current and direct current voltage.
- Resistance: Measures electrical resistance in ohms (Ω).
- Continuity: Checks for a complete electrical path, typically indicated by an audible beep.
- NCV (Non-Contact Voltage): Detects the presence of AC voltage without direct contact. The display will indicate 'L' for low voltage and 'H' for high voltage.
- Live Wire: Identifies live electrical wires.
- Phase: Detects electrical phase.

5. Maintenance
To ensure the longevity and accuracy of your TESMEN TSM-192 multimeter, follow these maintenance guidelines:
- Cleaning: Wipe the device with a dry, clean cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the multimeter in its provided storage bag in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Replacement: Replace batteries promptly when the low battery indicator appears. Refer to Section 3.1 for battery installation instructions.
- Inspection: Periodically inspect the test leads and the device for any signs of damage or wear. Do not use if damaged.
6. Troubleshooting
If you encounter issues with your TESMEN TSM-192 multimeter, consider the following common troubleshooting steps:
- No Display/Power: Check if the batteries are correctly installed and have sufficient charge. Replace batteries if necessary.
- Inaccurate Readings: Ensure the test leads are properly connected and not damaged. Verify that the measurement mode is appropriate for the task (though Smart Auto mode handles most common scenarios).
- No Continuity Beep: Confirm that the circuit being tested is de-energized and that there is a complete path.
- NCV Not Detecting: Ensure the NCV sensor is positioned correctly near the voltage source.
For persistent issues not resolved by these steps, please refer to the full user manual or contact TESMEN customer support.
