Unlike RF, microwaves and electric fields, these alternating dynamic magnetic fields can not be mitigated, unless you can have the powerlines buried, which costs north of at least 100k. Therefore it is essential to monitor these types of fields before committing yourself to a property near power lines or power infrastructure.
Monitoring the power grid’s dynamic background magnetic fields in built-up areas is necessary for full audit on-site field tests EMF assessments. Most professionals will leave a professional low-frequency meter overnight to log an event. This costly exercise is upwards of $500 for the service. The LFM-X Mode on the Mito Meter allows you to monitor your PowerGrid activity over a 12-hour duration. No PC or software requied. Activate LFM-X Mode in the bedroom or the place of interest you want to test and check the results twelve hours later. This simple, accurate and affordable process is a world first for 3-in-1 EMF meters.
LFM-X Mode Instructions
To activate LFM-X Mode, follow these steps and make sure you have a fully charged battery.
1/ Turn on the meter and select RF.
2/ Quickly move the MODE switch down to LFE Mode and back to RF Mode twice within two seconds.(RF>LFE>RF>LFE>RF) Two lights will start to blink, one orange, one red.
3/ Then move the Mode switch down one click to LFM Mode. (RF>LFM) Now you will see the LED lights sweeping left to right, giving you time to position the meter upright before the logging event starts. (As pictured above.)
After 20 seconds, the meter starts logging the event. Two lights will blink every few seconds, indicating the session is running. The meter cannot be moved, bumped or touched for twelve hours, as the magnetic sensors are sensitive to the slightest touch. Twelve hours later, the average and highest recorded A/C 50/60Hz RMS magnetic field values from the power grid will be displayed. If no lights are flashing, you are below Building Biology’s recommended sleeping area limit.
Placement & Position
Position at 90 degrees* in an upright position at least two meters from any electronics, appliances, or electrical cables.
Recommended Limit Guidelines
Ideally, you do not want to live or work in anything over 2mG/200nT. Pregnant mothers and children should avoid long-term exposures of more than 1mG/100nT. Sleeping areas ideally should be kept below 0.2mG/20nT.
The Mito Meter has up to 24 hours of battery life in LFM-X Mode. Check displayed 12-hour logging results before the meter battery goes flat.
Free EnvroSens software is available here for more in-depth analytics for monitoring PowerGrid background levels and data logging indefinitely. (PC, Android, or Mac) Android software has GPS mapping allowing you to overlay PowerGrid levels on GoogleMaps. (Ideal for mapping streets.)
When using the EnvroSens software, the LFM Mode magnetic field sensitivity extends down to 0.01 mG/milliGauss, (1 nT/nanoTesla) from 0.2 mG/milliGauss. (20 nT/nanoTesla) This is much lower and more accurate @50/60Hz than any other 3-in-1 EMF meter on the market today.
*The 90-degree mounting angle will not work if you are under or over distribution/transmission power lines. If this is the case, find the angle/axis on the meter in LFM Mode first with the highest reading and mount the meter in that axis/position for the twelve-hour logging session.
LFM-X Mode = Low-Frequency Mode & X for extended mode
