6. Käyttöohjeet

6.1 Virta päälle/pois

  • Kytke laite päälle pitämällä -painiketta painettuna Virta päälle/pois -painiketta, kunnes näyttö syttyy.
  • Sammuta laite pitämällä painiketta painettuna Virta päälle/pois -painiketta, kunnes näyttö sammuu.
  • The device features an auto-shutdown function after 15 minutes of inactivity to conserve battery life.

6.2 Measurement Modes (RF, E-field, H-field)

The MESTEK EMF02R can measure three types of electromagnetic fields:

  • RF (Radio Frequency) Radiation: Detects WiFi signals, 5G signals (30MHz ~ 8GHz), and microwave radiation.
  • E-field (Electric Field) Radiation: Measures electric fields emitted by household appliances like TVs, laptops, and microwaves.
  • H-field (Magnetic Field) Radiation: Measures magnetic fields from appliances such as refrigerators, washing machines, and air conditioners.

7. Understanding Readings and Radiation Sources

The MESTEK EMF02R helps identify common sources of electromagnetic radiation in your environment.

Images showing various common sources of radiation: routers, laptops, microwaves, refrigerators, and washing machines, with the MESTEK EMF02R detecting radiation from them.

Figure 9: Common sources of electromagnetic radiation.

  • Radio Frequency (RF) Sources: Routers, cell phones, 5G towers, microwave ovens (when operating).
  • Electric Field (E-field) Sources: TVs, laptops, power lines, ungrounded electrical appliances.
  • Magnetic Field (H-field) Sources: Refrigerators, washing machines, induction cookers, motors, high-voltage kaapelit.

When measuring, slowly move the meter closer to the suspected source. Observe the readings and the alarm indicators to determine the strength and type of radiation. If the radiation value reaches the yellow or red alarm zone, consider taking protective measures or increasing your distance from the source.
