3.1 Device Components

• LCD Digital Display: Shows electric field (E-field) and magnetic field (H-field) readings, battery status, alarm indicators, and measurement modes.
• Power Button (Red): Turns the device ON/OFF.
• AVG/VPP Button: Toggles between Average (AVG) and Peak (VPP) value measurement modes.
• HOLD/BEEP Button: Locks the current reading (HOLD) and toggles the sound alarm (BEEP).
• Battery Compartment: Located on the back, for 3 x 1.5V AAA batteries.

4. Setup

4.1 Battery Installation

1. Locate the battery compartment cover on the back of the MT525.
2. Slide the cover open in the direction indicated by the arrow.
3. Insert three (3) 1.5V AAA batteries, ensuring correct polarity (+/-) as marked inside the compartment.
4. Close the battery compartment cover securely until it clicks into place.

Note: Batteries are not included with the device and must be purchased separately.

5. Operating Instructions

5.1 Powering On/Off

• To power on the device, press the red Power Button. The LCD display will light up.
• To power off the device, press and hold the red Power Button for a few seconds until the display turns off. The device also features an auto power-off function to conserve battery life.

5.2 Taking Measurements

Once powered on, the MT525 will automatically begin measuring both electric field (E-field) and magnetic field (H-field) radiation simultaneously. Readings are displayed in real-time on the LCD.

Figure 5.1: Examples of using the MT525 to measure radiation from common household electronics like TVs, computers, and mobile phones.

• Electric Field (E-field): Displayed in V/m (Volts per meter).
• Magnetic Field (H-field): Displayed in µT (microTesla).
• The display also includes a radiation assessment indicator (Safe/Harmful) and a graphic display of the radiation value trend.

5.3 AVG/VPP Mode Selection

• Press the AVG/VPP Button to switch between Average (AVG) and Peak (VPP) value measurement modes.
• AVG (Average): Displays the average radiation value over a period.
• VPP (Peak): Displays the peak radiation value detected.

5.4 Data Locking (HOLD) and Sound Alarm (BEEP)

• Press the HOLD/BEEP Button once to lock the current readings on the display. Press it again to release the hold.
• Press and hold the HOLD/BEEP Button to toggle the sound alarm ON or OFF. When the sound alarm is ON and the measured radiation value exceeds the preset safe threshold, the device will emit an audible alert.
