2. Safety Information
Always observe safety precautions when using electrical testing equipment and laser devices. Failure to do so may result in injury or damage to the devices.
- TH202 Infrared Thermometer: This device measures surface temperature only. It is not intended for human or animal body temperature measurement. Do not point the laser directly at eyes or reflective surfaces. Avoid measuring through smoke or steam, as this can affect accuracy.
- B15 Voltage Tester: Always assume circuits are live until proven otherwise. Do not use if the device appears damaged. Ensure proper grounding when testing electric fences.
- Keep both devices away from water and extreme temperatures.
- Do not attempt to disassemble or modify the devices. Refer servicing to qualified personnel.
- Replace batteries promptly when the low battery indicator appears.

4. Setup
4.1. Battery Installation
Both the TH202 Infrared Thermometer and B15 Voltage Tester require AAA batteries for operation. Batteries are typically included with the product.
- Locate the battery compartment cover on the handle of the TH202 (refer to part 9 in the diagram) and on the rear of the B15.
- Open the cover.
- Insert the AAA batteries, ensuring correct polarity (+ and -).
- Close the battery compartment cover securely.

5. Operating Instructions
5.1. ANENG TH202 Infrared Thermometer Operation
- Power On: Press the measuring trigger button (part 8) to turn on the device. The backlit LCD will illuminate.
- Select Temperature Unit: Press the ℃/℉ button (part 3) to switch between Celsius and Fahrenheit.
- Laser Positioning: Press the Laser Positioning Switch (part 5) to activate or deactivate the laser pointer for precise targeting.
- Taking a Measurement: Point the thermometer at the target object. Ensure the distance-to-spot ratio (12:1) is considered for accurate readings. For example, at 12 inches distance, the measurement spot diameter is 1 inch. Press and hold the measuring trigger button (part 8). The temperature reading will appear on the LCD. Release the button to hold the reading.
- Temperature Alarm: The device features high and low temperature alarms. These can be configured via the MODE button (part 4). A long press on the MODE button allows entry into value settings for these alarms.
- Emissivity Adjustment: The TH202 allows for emissivity adjustment, which is crucial for accurate readings on different surface types. Consult the full manual for specific emissivity values for common materials. This setting is typically accessed via the MODE button.
- Auto-Off: The device will automatically power off after 15 seconds of inactivity to conserve battery life.

5.2. ANENG B15 Voltage Tester Operation
The B15 offers multiple testing functions for electrical circuits and components.
- Non-Contact AC Voltage Detection: Hold the tester near a wire, outlet, or electrical component. If AC voltage is present, the indicator lights will illuminate, and an audible alert may sound.
- Zero FireWire Detection: Insert the probe into the live (fire) wire. The tester will indicate the presence of a live connection.
- Self-Test Function: Activate the self-test function (usually by pressing a button or specific sequence) to ensure the tester is working correctly before use.
- Line Breakpoint Lookup: Move the tester along an insulated wire. The indicator will change or cease to indicate voltage at the point of a break in the line.
- Electrical On-Off Detection: Use the tester to determine if a circuit or device is receiving power.
- Battery Detection: The B15 can be used to check the voltage of small batteries.
- Flashlight: Press the flashlight button to illuminate dark work areas.
