- AVG/VPP Button: Toggles between Average (AVG) and Peak Value (VPP) measurement modes.
- Power / HOLD Button: Press briefly to power on/off. Press and hold to activate/deactivate data hold function.
- UNIT knap: Switches between different units for magnetic field measurement (uT/mG).
4. Opsætning og batteriinstallation
The ET925 requires 3 AAA batteries (not included) for operation.
- Find batterirummet på bagsiden af enheden.
- Skub batteridækslet op.
- Isæt 3 AAA-batterier, og sørg for at polerne (+/-) vender korrekt som angivet inde i batterirummet.
- Luk batteridækslet forsvarligt.
5. Betjeningsvejledning
5.1 Tænd/sluk
- Tænd: Tryk på Power / HOLD button briefly. The device will perform a self-test and display current readings.
- Sluk: Tryk på Power / HOLD button briefly again to turn off the device.
5.2 Udførelse af målinger
Hold the device with the 'Front Sensing Area' pointed towards the object or area you wish to measure. The electric field (E-field) and magnetic field (H-field) readings will be displayed simultaneously on the LCD.
5.3 Mode Switching (AVG/VPP)
Tryk på AVG/VPP knap til at skifte mellem:
- AVG (Average) Mode: Displays the average radiation value over time.
- VPP (Peak Value) Mode: Displays the peak (maximum) radiation value detected.
5.4 Dataholdefunktion
Sådan fryser du de aktuelle aflæsninger på displayet:
- Tryk og hold på Power / HOLD button. The 'HOLD' icon will appear on the screen.
- To release the data hold, press and hold the Power / HOLD knappen igen.
5.5 Enhedsskift
Tryk på ENHED button to cycle through available units for magnetic field measurement (uT or mG).
5.6 Radiation Assessment and Alarm
The ET925 provides a quick assessment of radiation levels using a three-color indicator and an audible alarm:
- Green (Safe): Radiation levels are within safe limits (Magnetic field: 0-1.99mG / 0-0.19uT). The environment is generally safe for activities.
- Yellow (Alert): Radiation levels are elevated (Magnetic field: 2-3.99mG / 0.2-0.39uT). Caution is advised, especially for sensitive individuals like babies, the elderly, or pregnant women. Consider reducing activity in the area.
- Red (Avoid): Radiation levels are dangerous (Magnetic field: greater than 4mG / 0.4uT). The screen will turn red, and an audible alarm will sound. It is advised to leave the area immediately.
The alarm threshold for the electric field is 40V/m.
5.7 Analog Bar Display
The analog bar on the screen provides a more intuitive visual representation of environmental radiation changes, allowing for quick trend observation.
