EMF829 ElectroSmog Instruction Manual
I.
Safety Instructions
Notes
1. Before measurement, Please check if the low power symbol (
) is displayed. If it
is displayed please replace the batteries.
2. Turn OFF the instrument and remove the battery when not in use for a long time.
3. When the electric field device is connected to the meter, please don’t vibrate the meter
especially in measuring.
4. The outside environment and unsuitable operation will influence the accuracy and
function.
Dangers Matters
1. In some cases, working near intense radiation sources may come about life risk.
2. Note that, when there is an electronic introducer (for example, pace maker) in human body,
it may be extremely dangerous in some cases.
3. The equipment operation shall comply with the local safety regulations.
4. The application of equipment that can produce conduction or consume electromagnetic
energy shall comply with its operation instructions.
5. Note that, the secondary radiant matters (for example, reflectors of metal walls) may cause
amplification effect of the electric field.
6. Note that, the electric-field strength near the periphery of radiation sources increases to be
inversely proportional to the third power of the distance. So, when approaching to small
radiant sources, you will immediately feel large electric-field strength (for example,
leakage of wave guide, induction furnace).
7. The tester for electric-field strength may underestimate the pulse signal, especially the
radar signal. As a result, it may have obvious measurement errors.
8. Testers for electric-field strength all have a specified limit on frequency response range.
When the spectrum component of the electric field exceeds such frequency range, it may
generally lead to incorrect estimate and tend to underestimate. Therefore, before using the
tester for electric-field strength, it shall firstly confirm that all the measured components
are within the frequency range specified by such tester.
