MESTEK EMF01R 5-in-1 EMF Meter Instruction Manual

1. Introduction

The MESTEK EMF01R is a versatile 5-in-1 multifunctional meter designed to detect electric fields (EF), magnetic fields (MF), and radio frequency (RF) fields. Additionally, it measures ambient temperature and humidity. This device is equipped with a built-in electromagnetic radiation sensor that processes and displays radiation values on a color LCD screen. It assists users in identifying radiation sources and taking appropriate preventive measures.

5. Operating Instructions

5.1 Measurement Modes

The device supports three primary measurement modes: RF, Electric Field (E-field), and Magnetic Field (H-field).

• RF (Radio Frequency): Short press the RF button to enter RF measurement mode. This measures high-frequency signals from sources like 5G, cell towers, and Wi-Fi (30MHz to 8GHz).
• E-field (Electric Field): Short press the SEL button to cycle through measurement modes. The screen will display "E-field" for electric field radiation measurement.
• H-field (Magnetic Field): Continue short pressing the SEL button until "H-field" is displayed for magnetic field radiation measurement.

5.2 Data Functions (AVG/MAX/HOLD)

• AVG/MAX: Short press the AVG/MAX button to switch between average and maximum readings.
• HOLD: Short press the HOLD button to lock the current data on the screen. Press again to unlock.

5.3 Temperature and Humidity Measurement

The device continuously displays ambient temperature and humidity. To switch temperature units:

• Press and hold the SEL button to toggle between Celsius (℃) and Fahrenheit (℉).

5.4 Alarm Function and Display Interpretation

The MESTEK EMF01R features a simulated analog display with three color zones (Green, Yellow, Red) and an audible alarm to indicate radiation levels:

• Green Zone: Indicates low radiation levels.
• Yellow Zone: Indicates moderate radiation levels. The device will emit a buzzer sound, suggesting protective measures or increased distance from the source.
• Red Zone: Indicates high radiation levels. The buzzer will be more rapid, signaling a need for immediate action.

Refer to the table below for specific thresholds:

6. Maintenance

• Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Storage: Store the device in its carry bag in a cool, dry place when not in use.
• Battery Replacement: Replace batteries promptly when the low battery indicator appears to ensure accurate readings and prevent damage.

7. Troubleshooting

• Device does not power on: Ensure batteries are correctly installed and fully charged. Replace if necessary.
• Inaccurate readings: Ensure the device is not near strong magnetic fields or other interference sources that could affect its sensors. Calibrate if a calibration option is available (refer to the full user manual for advanced features).
• No sound from alarm: Check if the buzzer function is enabled. Refer to the full user manual for instructions on enabling/disabling the alarm.
