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 10 Hz - 3 kHz 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
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 100 V/m or 2000 V/m
range using the "RANGE" key:
- 100 V/m range
- 2,000 V/m range
The range can be changed by pressing the
"RANGE" key.
Low bat:
Low battery: the "HOLD" symbol blinks.
Auto-off:
The appliance switches off automatically after
30 minutes if no keys are used (the
appliance can be reactivated by pressing
one of the keys). A sound signal is given 2
secs. before automatic switch-off.
Switching off the VX003:
Keep the "ON/OFF" key pressed down for 2 secs. ; a high
sound signal will be emitted until the key is released.
