Electromagnetic field from TV with a diagonal less than 51 cm (20”) is measured at a distance of 50 ± 1 cm in front, behind and next
to the TV. When screen diagonal is more than 51 cm, the EM field is measured the same way at a distance of 100 ± 1 cm. The device
must be preliminarily turned on and work at least 20 minutes before measuring.
Electromagnetic Field from PC
The electrical field strength from PC ranging from 5 Hz to 2000 Hz should not exceed 25 V/m (volt per meter). The magnetic flux
density from a PC ranging from 5 Hz to 2 KHz should not exceed 0.25 mcTl (microtesla).
Electromagnetic field is measured at 50 cm distance from the screen.
"Review" mode does not have a set trigger threshold; it just displays a current electrical and magnetic field indication.
In "EM field" mode, the following information is displayed:
1. Electric fields strength;
2. Magnetic field strength;
3. Measurement mode.
There are four electromagnetic field measurement modes in the device:
- EM field in facilities;
- EM field in living area;
- EM field from domestic appliances;
- Review.
You can switch modes by pressing LEFT and RIGHT icons on the screen or by LEFT and RIGHT buttons on
the device case. In order to exit EM field mode, press X icon on the screen or press and hold LEFT button
on the device.
When the safe threshold of electric or magnetic field in any mode (except "REVIEW" mode) has been
exceeded, the indicator will have red color.
Water Measurement (Quality Evaluation) – TDS Meter
Water quality measurement is intended for quality evaluation of drinking water, as well as of water from treatment systems such as
hydroponics, fish tanks, swimming pools, domestic appliances and from water wells.
The device measures the amount of solid particles that have been dissolved in water (TDS- total dissolved solids) per 1 million water
particles – ppm (parts per million).
