To get as accurate of a reading as possible, always
point the top of the meter (sensors) to the source.
You can hold the meter at the lower part, or just
simply place the meter near the target source.

FAQ:
1. Is GQ Meter designed for general use purpose or professional
measurement?
It is for general use purpose.
2. Is your meter designed for beginner users or experienced users?
It is for both. Basic features are for beginners. Advanced features for
experienced users to explore.
3. I am a beginner, how do I start?
Power on the meter and keep it on the All-in-one screen. You are able to
read EMF, RF and EF from screen.
4. What makes the GQ EMF meter unique?
Affordable, cost effective with affluent features. The possible source
identification and RF browser features are exclusive in the market.
5. Why is my reading different from other meters?
In the real environment, EMF,RF and EF waves are always mixing and
changing constantly. The EMF meters also come in all shapes and sizes,
testing various frequencies. It is normal that the EMF meter’s readings
keep changing in a range.
6. Why is my EMF reading higher than the reading from power
company’s EMF meter?
One possible reason is the different detection range of frequency.
Power company’s meter only focus on the ELF, the frequency from 50 to 60
Hz. GQ meters can detect the frequency range from 1Hz to 400kHz.
7. Why there is no reading on my smart meter?
Smart meter emits RF periodically; it transmits data in every fixed time
interval. Some smart meters only transmit data once a day. Meanwhile,
others may transmit the data every minute. Use RF Browser to see the
transmitting pulses. Turn on the data logging to monitor it for a long period
so you can download the transmission information later.

8. Why is my reading changing?
In the real world, generally, there will always be a wide mixture of signals
from multiple sources around you. Those signals may have different
frequencies, orientations, or digital characteristics. Moreover, they are
changing from time to time, space to space. These differing aspects will
impact the readout.
9. What should I do if I think that the reading is not correct?
Test a couple of times to get the reading and take the average of those
readings.
10. What should I do if my meter is defective?
Please call or email GQ Electronics LLC. The staff will arrange the return
regardless of where you purchased the meter.
11. Why does the reading change when I put my hand on the meter?
Human body has electrostatic discharge (ESD, the sudden flow of electricity
between two electrically charged objects caused by contact, an electrical
short or dielectric breakdown). This impacts the EF reading.
12. What is the difference between a single axis and a triple axis gauss
meter?
Magnetic fields are oriented in space; a sensor will only detect the field
properly if it is aligned with the field. A single axis meter has only one
sensor in it, which makes it easier to get an incorrect reading than actual
reading. This type of meter is cheap due to only measuring partial radiation.
A three-axis meter has 3 sensors in it, all aligned at right angles to each
other. This type of meter is always correctly aligned. It takes less time but
generally costs more than the single axis counterpart.
13. Can you describe a bit more on RF radiation?
RF(Radio Frequency) radiation is dynamic in nature and can be impacted by
varies factors: Frequency, orientation, time and place.
10

Every meter has a specified frequency range and it has
different frequency response (Nonlinear response)
A meter only responds to a portion of the RF spectrum.
Location is one of the most important factor impacts the RF
reading. If you have taken RF readings, you know that the
levels fluctuate widely from one moment to the next and from
one location to the next. Even moving the meter a few inches
to one side or another can have a large impact on reading.
14. Why the meter has different RF reading on different direction?
All RF signals have an orientation in space. They may be vertically or
horizontally polarized, they may be circularly polarized. The RF signal also
can be reflected by objects. The orientation of the meter’s antenna
direction to the signal will greatly impact the meter’s ability to detect the
signal. When multiple signals are present (with different orientations), it is
difficult to define the antenna orientation.
15. What is different between RF Standard mode and RF Sensitive mode?
The Standard mode on this meter is referring to average reading. Which is
the reading been calibrated to a RSM reading standard. The Sensitive mode
mostly reports RF pulse peak value. Most signals today are digital. Digital
signals are RF pulse signal (composed of a series of short bursts pulses). The
amplitude of pulses can differ by many times, sometimes more than 100
times.
