Frequently Asked Questions - NF-601 Noyafa

How do I power on/off the NF-601?

To power on, briefly press the power button (marked with a speaker icon). To power off, long press the same button.

How do I use the NF-601 to detect electromagnetic radiation?

After powering on, bring the device close to the object being tested. The electric and magnetic field values will be displayed on the screen. The device will show 'Safe' if within safe limits and 'Harmful' with an alarm if exceeded.

What is the difference between Average Mode and Peak Mode?

Average Mode shows real-time field intensity. Peak Mode shows the highest detected value and automatically locks it. Press the '##' button (likely the middle button) to switch between modes.

How do I lock or unlock the reading?

During detection, briefly press the lock button (likely the left button) to freeze the current reading. Press it again to unlock and resume live measurement.

How do I activate silent mode?

Long press the lock button to toggle silent mode on/off. When silent mode is active, the device will not emit alarm sounds.

What are the alarm thresholds for electric and magnetic fields?

The electric field alarm threshold is 45 V/m, and the magnetic field alarm threshold is 0.4 μT.

What type of batteries does the NF-601 use and how do I replace them?

The device uses 2 x AA batteries. Open the battery compartment (likely on the back) to replace. Remove batteries if not used for a long time.

Can I use the NF-601 to detect radiation from base stations or high-voltage lines?

Yes, the NF-601 is designed for electromagnetic radiation detection of appliances, high-voltage lines, base stations, etc. It measures both electric and magnetic fields simultaneously.

Is the NF-601 calibrated or do I need to calibrate it?

The device is factory calibrated. No user calibration is needed. If accuracy is a concern, contact professional service.

What does the temperature display on the screen indicate?

The device also shows the ambient temperature (in °C) as an additional feature, displayed on the top right of the LCD.

USER MANUAL NF-601 Noyafa

Dear user, thank you for purchasing this product. Please read the Instructions carefully before use.

Please read and understand the safety precautions before using or servicing this equipment.

Do not place the device in dusty, humid and high temperature (above 40°C) places.

Overview

Electromagnetic radiation refers to the phenomenon of energy propagating through space in the form of electromagnetic waves. The higher the frequency of electromagnetic radiation, the greater the harm to the human body. Although the pollution of electromagnetic radiation is invisible and intangible, it may bring harm to people's health.

NF-601 is mainly used for electromagnetic radiation detection of electrical appliances, high-voltage lines, base stations, etc., to help people stay away from radiation sources and avoid radiation hazards!

Operating instructions

1. Power On/Off

To power on the device, lightly press the power button " ", To power off, long press power button " ",

2. Detection

① After powering on, bring the device close to the object being detected, and the electric/magnetic field intensity value will be displayed on the device screen.
② The electromagnetic radiation value is within the safe range, the screen will display "Safe". The electromagnetic radiation value exceeds the safe range, the device will emit an alarm sound and display "Harmful".

3. Button Operations

① When the electrical/magnetic field value is detected, press the "HOLD" button lightly to lock the current data. Press the "HOLD" button again to unlock it.
② Long press the "HOLE" button to activate the silent mode. Long press the "HOLE" button again to deactivate silent mode.
③ Press the " _11N_21 " button lightly to switch between "Average Mode" and "Peak Mode".

④ Average Mode: Indicates the real-time electrical/magnetic field intensity.

Peak Mode: Indicates the highest detected electrical/magnetic field intensity. In this mode, the highest value is automatically locked.
