VX0100: the following symbol is displayed

To access the battery, remove the screw using a tool and remove the cover.

3. GENERAL DESCRIPTION

The VX0003 and VX0100 capacity type testers are single pole, i.e. they carry out asymmetrical measurements on the exposed metal parts. The connection of these testers to the input amplifier used as an inverting amplifier, guarantees a very low difference in potential at the antenna terminals, and, therefore, no effect on the fields being measured.

The measurement part can be referenced by touching the appropriate zone on the rear face with a finger or by earthing the appliance.

You are reminded that the intensity of an electric field is inversely proportional to the distance from its source (10 V/m measured at 1 m are equivalent to 100 V/m measured at 10 cm).

3.1.VX0003

The tester indicates the value of low frequency electric fields. The measurements are made in the 10Hz - 3kHz bandwidth.

Warning: moving the tester too quickly will cause detection of parasite electric fields.

It has the following additional functions:

Sound signal: Sound indicating the measured field level. The sound emitted is proportional to the measured field intensity. This is switched on and off using the key.

Hold: Keeps the measured value until "HOLD" is pressed again. Activate and deactivate by applying a short push on the "HOLD" key.

Range: Manual choice of the 100V / m or 2000 V/m range using the "RANGE" key: -100 V/m range green scale -2,000 V/m range red scale The range can be changed by pressing the "RANGE" key.

4.2. Powering up (press "ON")

4.2.1.VX0003

Phase 1: LED test

1. The green "RANGE" LED and the red "HOLD" LED, as well as the 2000 V/m LED light up for about 2 secs.
2. Then all the LEDs light for about 3 secs.

Phase 2: Automatic range configuration at start-up

1. The green "RANGE" LED becomes red.
2. Indication of the range: 2000 V/m by default, red scale.
3. The "HOLD" LED stops.
   If the measured values are >120% of their nominal range, then the "RANGE" LED blinks and the sound signal stops

4.2.2.VX0100

1. "ON" is displayed on the LCD for about. 2 secs.
2. All the segments are displayed for about. 3 secs.
3. The measurements are displayed.
   If you keep the "ON" key pressed down the VX0100 displays the software version before passing on to phase 3. If the measured values are >120% of their nominal range the VX0100 displays "OL" and the V/m segment will blink.

4.3. Operating the VX0003

the persons gathering there.

• Next sweep the premises horizontally in relation to potential sources.

• Try and find the maximum field values either using the bargraph, or by listening to the highest sound signal emitted by the appliance.

• For source located in the floor or ceiling change the appliance's position so that the sensor electrode is parallel to these surfaces:

• Floor VX0003 is horizontal; the reading is on the top.

• Ceiling VX0003 is horizontal; the reading is on the bottom.

4.4. Operating the VX0100

• Next sweep the premises horizontally in relation to potential sources.
• Try to find the maximum field values either using the LCD display, or by listening to the highest sound signal emitted by the appliance.
• For sources located in the floor or ceiling change the appliance's position so that the electrode surface of the sensor is parallel to these surfaces.
  The LCD is not operational for an electric field greater than 3000 V/m. The LCD resumes operation when the electric field is below this value.

5. DIAGNOSTICS AND REMEDIES

These testers measure the "RMS" intensity of electric fields in V/m and check them in compliance with current and future standards and directives:

Methods of measuring electro-magnetic fields emitted by household appliances and assimilated in relation to human exposure - publication: January 2007.

5.1. Remedies related to the electric installation

1. Connect and check the electrical installation's earth correctly.
2. Check the levels of emitted electric fields (see § 5.3).

3. For appliances that are not earthed, check that the Ph/N connection is made correctly. If it is reversed the level of the fields will be much higher (e.g.: bedside lamp with a single pole switch).

4. Use devices to limit electric fields:

5. pre-cabled sheaths with shielded H07-VU phase wires.

6. shielded wires and cables. These cables are most efficient when the screens are connected to the earth network. The electric field is directed to the earth using the shielding connected to the earth.
7. equipment casing fitted with a metal screen at the rear of the casing. This is used to reduce electric radiation from the case + cable + equipment.

8. an automatic two pole current cut-off device. This is a box that is fitted after the fuse corresponding to the room's circuit. It is designed to automatically cut-off electric voltage causing electric fields as soon as the last appliance or light is switched off. It switches power back on whenever a switch in the room is used.

9. Place the potential sources of fields at a safety distance from the zones where persons gather for long periods of time or vice versa (see examples § 5.2).

Chapter II
5.2. Equipment / Safety distances and precautions
- In order to ensure good sleep and well-being inside a home, the intensity of electric fields in rest and sleeping areas should be limited.
