Safety Information
Always observe safety precautions when working with electrical systems or inspecting materials. Failure to do so may result in injury or damage to the device.
- Do not use the voltage tester if it appears damaged or is not operating correctly.
- Always verify the tester's operation on a known live circuit before and after use.
- The voltage tester is rated for CAT. III 1000V and CAT. IV 600V. Do not exceed these ratings.
- Keep the moisture meter pins clean and dry when not in use.
- Do not attempt to measure moisture in live electrical circuits.
- Replace batteries promptly when the low battery indicator appears.

Setup
Battery Installation
Both the TN-213 Voltage Tester and TWM-186 Moisture Meter require batteries for operation. Typically, these devices use standard AAA batteries. To install or replace batteries:
- Locate the battery compartment cover on the back or bottom of the device.
- Open the cover by sliding or unscrewing it.
- Insert the batteries, ensuring correct polarity (+ and -).
- Close the battery compartment cover securely.
- Perform a quick test to ensure the device powers on.
Initial Inspection
Before first use, inspect both devices for any signs of damage, such as cracks in the casing or bent probes. Do not use if damage is present.
Operating Instructions
TESMEN TN-213 Voltage Tester
The TN-213 is a non-contact AC voltage detector designed for quick and safe electrical checks.
- Power On: Press the power button (usually marked with a power symbol) to turn on the device. The LCD screen will illuminate.
- Sensitivity Adjustment: The TN-213 features dual-range sensitivity.
- High Sensitivity (12V-1000V): Ideal for detecting lower voltages or tracing wires from a distance.
- Low Sensitivity (70V-1000V): Suitable for standard household voltage detection, reducing false positives.
Press the sensitivity button (often marked 'S' or with a sensitivity icon) to switch between ranges. The current range will be indicated on the LCD.

- Voltage Detection: Bring the tip of the tester close to the wire, outlet, or electrical component you wish to test.
- If AC voltage is detected, the tester's tip will glow red, an audible buzzer will sound, and the LCD will display the voltage strength.
- The voltage strength is visualized with a percentage and an analog bar on the LCD for clear indication.

- Auto Shutoff: The device will automatically power off after a period of inactivity to conserve battery life.
TESMEN TWM-186 Pen Moisture Meter
The TWM-186 is a pin-type moisture meter for measuring moisture content in wood and construction materials.
- Power On: Press the power button to turn on the device.
- Select Material Mode: The TWM-186 offers different modes and calibration scales for various materials.
- Wood Mode: For measuring moisture in various types of wood (e.g., 6.8% to 58%).
- Construction Material Mode: For materials like concrete, plaster, and drywall (e.g., 0% to 24.5%).
Refer to the device's manual or on-screen indicators to select the appropriate mode for your material. Press the 'M' (Mode) button to cycle through available modes.

- Measurement: Carefully press the two metal pins into the surface of the material you wish to measure. Ensure both pins penetrate the surface for an accurate reading.
- Reading Interpretation: The LCD screen will display the moisture content percentage. The TWM-186 features a three-color backlight system for quick interpretation:
- Green: Indicates a dry or acceptable moisture level.
- Orange: Indicates a moist or elevated moisture level.
- Red: Indicates a wet or high moisture level, suggesting potential issues.

- Hold Function: Some models may include a 'Hold' button to freeze the current reading on the display.
- Auto Shutoff: The device will automatically power off after a period of inactivity to conserve battery life.
Versatile Applications
The TWM-186 is suitable for a wide range of applications, including:
- Wood Processing and Lumber Inspection
- Wood Floor Installation and Repair
- Checking Firewood for optimal burning
- Detecting moisture on wall surfaces (e.g., drywall, plaster)
- General home inspection for water damage

Maintenance
- Cleaning: Wipe the devices with a dry, soft cloth. Do not use abrasive cleaners or solvents. For the TWM-186, ensure the pins are clean and free of debris after each use.
- Storage: Store both devices in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.
- Battery Replacement: Replace batteries when the low battery indicator appears on the display to ensure accurate readings and proper operation.
- Durability: The TESMEN TN-213 Voltage Tester is rated IP66, indicating it is shielded from dust and powerful water jets. While robust, avoid unnecessary exposure to water and dust for prolonged device life.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Dead or incorrectly installed batteries. | Check battery polarity; replace batteries. |
| TN-213 gives inconsistent voltage readings. | Low battery; interference; incorrect sensitivity setting. | Replace batteries; move away from other electrical devices; adjust sensitivity. |
| TWM-186 shows "Err" or inaccurate moisture readings. | Pins not fully inserted; dirty pins; incorrect material mode. | Ensure pins penetrate surface; clean pins; select correct material mode. |
| Auto shutoff occurs too quickly. | Normal operation to save battery. | No action needed; simply power on again. |
If problems persist, please contact TESMEN customer support.
