1. Introduction
The Generic DT-1130 is a handheld digital electromagnetic radiation detector designed for measuring electromagnetic fields (EMF) in various environments. This device provides readings for both low-frequency electric fields (V/m) and high-frequency magnetic fields (µW/cm²).
It is suitable for detecting radiation from common sources such as household appliances, office equipment (computers, copiers, fax machines), power cables, monitors, and other electronic devices.
2. Safety Information
- Read this manual thoroughly before operating the device to ensure safe and correct usage.
- Do not attempt to open or modify the device. Unauthorized modifications may void the warranty and pose safety risks.
- Keep the device away from water and high humidity to prevent damage.
- Avoid exposing the device to extreme temperatures or direct sunlight for prolonged periods.
- Dispose of batteries according to local regulations. Do not incinerate batteries.
- This device is for informational measurement purposes only and should not be used as a substitute for professional safety equipment or advice.

4. Setup
4.1. Battery Installation
The DT-1130 requires one 9V battery (not included) for operation.
- Locate the battery compartment on the rear of the device (refer to Image 3.2, item 6).
- Slide open the battery compartment cover.
- Connect a new 9V battery to the battery clip, ensuring correct polarity (+ to + and - to -).
- Place the battery into the compartment and close the cover securely.

5. Operating Instructions
5.1. Powering On/Off
- To turn the device ON, press the Power button (Image 3.2, item 1). The display will illuminate.
- To turn the device OFF, press the Power button again.
5.2. Taking Measurements
Once powered on, the DT-1130 will immediately begin measuring electromagnetic radiation. The display will show readings for both low-frequency (V/m) and high-frequency (µW/cm²) radiation.
- Position the detector near the object or area you wish to measure.
- Observe the readings on the 3-digit liquid crystal display.
- The measurement interval is approximately 0.4 seconds, providing near real-time updates.
- If radiation levels exceed a preset threshold, the red Alarm indicator (Image 3.2, item 4) will light up.
5.3. Data Hold Function
- To freeze the current reading on the display, press the Data Hold button (Image 3.2, item 2).
- The displayed value will remain constant until the button is pressed again.
- Press the Data Hold button a second time to resume live measurements.
6. Maintenance
6.1. Cleaning
To clean the device, gently wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners, solvents, or immerse the device in water.
6.2. Battery Replacement
When the display becomes dim or the device fails to power on, it is time to replace the 9V battery. Follow the battery installation steps outlined in Section 4.1.
6.3. Storage
When not in use for extended periods, remove the battery to prevent leakage and store the device in a cool, dry place, away from direct sunlight and extreme temperatures.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn on. | Low or dead battery; incorrect battery installation. | Replace the 9V battery with a new one, ensuring correct polarity. |
| Display is dim or flickering. | Low battery power. | Replace the 9V battery. |
| Readings seem inaccurate or inconsistent. | Interference from other electronic devices; device malfunction. | Move away from other strong electromagnetic sources. If problem persists, contact support. |
| Alarm indicator is constantly on. | High radiation levels detected; sensor malfunction. | Move to an area with lower potential radiation. If the alarm persists in a known low-radiation environment, contact support. |
