4.2 Basic Measurements (4000 Counts)
- AC Voltage (V~): Connect test leads across the AC voltage source. The meter will display the AC voltage.
- DC Voltage (V=): Connect test leads across the DC voltage source. The meter will display the DC voltage.
- Resistance (Ω): Ensure the circuit is de-energized. Connect test leads across the component to measure resistance.
- Continuity (♫): Ensure the circuit is de-energized. Connect test leads across the circuit path. A beep indicates continuity.
- Non-Contact Voltage (NCV): Use the NCV sensor area to detect AC voltage without direct contact.

5. Operating Instructions: TESMEN TBF-200 Brake Fluid Tester
The TBF-200 provides a quick and accurate method to check the moisture content in brake fluid.
5.1 Measuring Brake Fluid Moisture Level
- Ensure the vehicle engine is off and cool.
- Locate the brake fluid reservoir. Carefully remove the cap.
- Turn on the TBF-200 tester.
- Carefully insert the flexible 8.5-inch gooseneck probe into the brake fluid reservoir, ensuring the metal probes are fully submerged in the fluid.
- Wait for the reading to stabilize on the digital display. The tri-color backlight alarm will indicate the moisture level:
- Green: Brake fluid is in good condition (low moisture).
- Yellow: Brake fluid has moderate moisture; consider replacement soon.
- Red: Brake fluid has high moisture content; immediate replacement is recommended.
- After testing, remove the probe and clean it thoroughly with a dry cloth.
- Replace the brake fluid reservoir cap securely.

- Storage: Store both devices in their provided storage bags in a cool, dry place, away from direct sunlight and extreme temperatures.
- Battery Replacement: Replace batteries promptly when the low battery indicator appears to ensure accurate readings and prevent damage from battery leakage.
- Probe Inspection: Periodically inspect the probes of both devices for any signs of damage or corrosion. Replace if necessary.
7. Troubleshooting
If you encounter issues with your TESMEN TBF-200 or TM-510, refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Dead or incorrectly installed batteries. | Check battery polarity and replace with fresh batteries. |
| Inaccurate readings (TBF-200). | Dirty probes, insufficient immersion, or old brake fluid. | Clean probes thoroughly. Ensure probes are fully submerged. Re-test. If readings remain inconsistent, consider brake fluid replacement. |
| No reading (TM-510). | Incorrect lead connection, open circuit, or out of range measurement. | Ensure test leads are properly connected. Verify the circuit is complete. Check if the measurement is within the device's specified range. |
| Display is dim or flickering. | Low battery. | Replace batteries. |
