4. Product Features

• Wide Application: Detects invisible radiation from various sources such as TVs, induction cookers, refrigerators, cell phones, computers, electrical wires, Wi-Fi signals, and other low-frequency home appliances.
• Accurate Measurement: Measures electromagnetic fields from 0.1 to 199.9mG (resolution 0.1mG/0.01µT), electric fields from 1 to 1999V/M (resolution 1V/M), and ambient temperature from 0℃ to 50℃ (32℉ to 122℉).
• Multifunctionality: Includes data hold, maximum value measurement, one-key data lock, manual/auto shut-off, adjustable safe value settings, and a large LCD display with sound and light alarm system.
• Larger Backlight Display: Ensures clear readings even in low-light conditions. The backlight and flashlight can be toggled by a long press of the MAX/BL button.
• Sound & Light Alarm: Provides visual and audible alerts based on radiation intensity:
  • Green light (Mute): Less than 4mG
  • Yellow light (Low sound frequency): 4mG - 40mG
  • Red light (High sound frequency): More than 40mG

6. Setup

6.1 Battery Installation

1. Locate the battery compartment cover on the back of the device.
2. Slide or unclip the cover to open the compartment.
3. Insert the included 9V battery, ensuring correct polarity (+ and - terminals match).
4. Close the battery compartment cover securely.

6.2 Powering On/Off

Press the red ON/OFF button to turn the device on. Press and hold the ON/OFF button again for a few seconds to power it off.

7. Operating Instructions

7.1 Basic Measurement

1. Turn on the device using the ON/OFF button.
2. The device will default to EMF measurement (mG or µT). To switch to Electric Field (V/M) measurement, press the SEL button. Press again to cycle back to EMF.
3. The ambient temperature will be displayed in the upper left corner. To change the temperature unit between Celsius (℃) and Fahrenheit (℉), press the ℃/℉ button.
4. Move the meter slowly around the area or object you wish to test. The display will show real-time readings.

7.2 Data Hold and Max Measurement

• Data Hold: During measurement, a short press of the MAX/BL button will freeze the current reading on the display. The "HOLD" icon will appear. Press again to release and resume real-time measurement.
• Max Measurement: When in Data Hold mode, the display will show the maximum value recorded since the device was powered on or the last reset.

7.3 Backlight and Flashlight

To activate or deactivate the LCD backlight and the integrated flashlight, press and hold the MAX/BL button for approximately 2 seconds.

7.4 Auto Shut-off

The device features an automatic shut-off function to conserve battery power. If no operation is performed for a certain period (typically 15 minutes), the meter will power off automatically. This feature can usually be disabled or enabled through specific button combinations (refer to the included printed manual for advanced settings if available).

7.5 Wide Applications

8. Measurement Interpretation (Sound & Light Alarm)

The ENGINDOT MET01 provides clear indications of radiation intensity through a combination of colored LED lights and audible alarms:

• Green Light (Mute): Indicates a low radiation level, typically less than 4mG. The sound alarm is muted in this range.
• Yellow Light (Low Sound Frequency): Indicates a moderate radiation level, ranging from 4mG to 40mG. A low-frequency sound alarm will be active.
• Red Light (High Sound Frequency): Indicates a high radiation level, exceeding 40mG. A high-frequency sound alarm will be active, signaling a potentially significant radiation source.

The sound alarm can be toggled on or off by a short press of the ON/OFF button while the device is powered on.

9. Maintenance

• Cleaning: Use a soft, dry cloth to clean the exterior of the device. Do not use abrasive cleaners or solvents.
• Storage: When not in use for extended periods, remove the battery to prevent leakage and store the device in a cool, dry place.
