FAQ's of Metravi EMF-823 ELF Electromagnetic Field Meter:

Q: How does the Metravi EMF-823 measure electromagnetic field strength in the ELF range?

A: This meter utilizes a single-axis sensor to accurately detect electromagnetic fields in the extremely low frequency range (30~2000Hz). It displays results in either milligauss (mG) or nanotesla (nT) with a high resolution of 1mG / 10nT and a response time of about 0.4 seconds.

Q: What kind of applications is the EMF-823 best suited for?

A: The EMF-823 is ideal for measuring electromagnetic field strength near power lines, electrical appliances, and industrial equipment where ELF field detection is needed. It is widely used in environmental monitoring, safety checks, and EMF surveys.

Q: When should I replace the battery in the EMF-823?

A: You should replace the 9V battery when the low battery indication appears on the LCD display. This allows you to maintain accurate and uninterrupted measurements, as the typical battery life is approximately 100 hours of continuous use.

Q: Where can the EMF-823 be used, considering temperature and humidity conditions?

A: The meter is suitable for use in environments with operating temperatures from 0C to 50C and humidity levels between 0% and 80% RH, provided there is no condensation. For storage, the temperature range is -10C to 60C.

Q: What is the process for using the EMF-823 to measure electromagnetic fields?

A: Simply switch on the meter, hold it in the area of interest, and let the device sample the field at 2.5 times per second. The LCD will show the real-time measurement, and if you encounter fields exceeding the device's range, the maximum value will be displayed.

Q: How does ambient temperature compensation benefit my measurements?

A: Ambient temperature compensation ensures that the readings taken with the EMF-823 remain accurate even when environmental temperatures fluctuate, making your field assessments more reliable under varied conditions.

Q: What are the benefits of using a CE-marked electromagnetic field meter like the EMF-823?

A: CE certification confirms that the EMF-823 meets internationally recognized safety and quality standards. This assures users of the device's dependability, credibility, and suitability for both professional and personal electromagnetic field monitoring assignments.
