Transmitter buttons and functions
LED indicator
The LED ashes when the transmitter is on.
On/Off button A
Button to switch the transmitter on and off. Active transmitter is
indicated by a ashing light in the LED. When there is voltage to
one of the probes the instrument cannot be switched off.
If the button is pressed while there is voltage to one of the probes,
the transmitter transmits information to the receiver about the
conguration of the outlet (how the outlet is connected).
The probes must be voltage free to switch off the transmitter.
The button is held in for 0.5 seconds.
RCD/RCOB test button B
When this button is pressed a 30 mA fault current is generated
between phase and ground terminal. The duration of the fault
current is a maximum of 300 ms.

Areas of use
The VS3 is a patented tool for electri-
cians in their daily installation work. It is
especially designed for fault tracing and
fuse detection in single phase 230V ap-
plications during maintenance and repair.
VS3 consists of two battery powered sec-
tions: a transmitter and a receiver. The
transmitter and the receiver communicate
via the radio frequency 869 MHz.
The following functions are available
Outlet conguration
• Shows how a single phase outlet is con-
nected
• Measures voltage and frequency in the
electrical outlet
Phase connections
• To identify phase connections for protec-
tive apparatus and consumers in relation-
ship to the electrical outlet to which the
transmitter is connected
Fuse connections
• To identify protective apparatus (fuses,
mini circuit breakers, RCD and RCBOs)
in relation to a given outlet
RCD tests
• To check a 30 mA RCD function and trip
time.
Introductory description of the Tracker’s functions and operating method
Automatic switch-off
The transmitter and the receiver switch off
automatically.
The receiver switches itself off after approxi-
mately 1 hour if an electric eld has not been
applied to the top end of the receiver.
The receiver switches off automatically after
approximately 1 hour.
An audible signal in the receiver sounds
one minute before the transmitter switches
off. One press on the transmitter’s Abutton
means that the transmitter is active for a
further hour.
Manual switch-off
The transmitter and the receiver can also be
switched off manually.
The transmitter must be unpowered to be
switched off.
Connection checks
There are two symbols on the receiver
display which show the quality of the radio
connection.
The symbol shows that the receiver is
receiving data from the transmitter and the
symbol shows the strength of the incom-
ing signal from the transmitter.
If the symbol is dis-
played in the upper eld
it means that there is an-
other transmitter nearby
that the receiver is receiving data from.
Always check that the other transmitter is
not interfering with your own readings.
Range
The transmitter and receiver communicate
with each other via radio on 869 MHz and
have good contact with each other up to a
distance of 1.2 km line of sight.
If there are many, thick walls or other obsta-
cles, the range is limited.

For safe use of the VS3 we recommend that
you read through the manual and under-
stand how the instrument functions. Read
the special paragraphs covering the instru-
ment’s limits carefully.
The following symbols are used in the user
manual
This text contains important informa-
tion, for example about the instru-
ment’s limits
This text contains information and
tips which can be helpful to clarify
the function.
The transmitter and the receiver are
synchronised to each other. If a new
transmitter is to be used with the
receiver the receiver must be set to
communicate with it. Read more on
relevant page of the user manual.
Never use the instrument if it seems
damaged
Never open the instrument other than
to change batteries. There are no
parts inside that can be replaced by
anyone other than authorised person-
nel.
If the instrument will not be used
for 30 days the batteries must be re-
moved to prevent leakage damage
Test the transmitter by switching it on,
connecting it to an outlet with known
voltage and reading off the voltage
and frequency of the receiver.

The transmitter in the wall outlet and
the handheld receiver communicate
by radio signal. The signal can be
interrupted by other strong transmit-
ters or weakened by long range or
screening materials, walls and roofs.
Check that there is sufcient signal
strength using the symbol on the re-
ceiver display.
The instrument may only be cleaned
using a rag with a mild soap solution.
The instrument must be dry before
use.

4. Press the transmitter’s
Abutton and hold it in
5. The display shows the
conguration and volt-
age and frequency of
the outlet.
6. The voltage and fre-
quency are also dis-
played when the trans-
mitter’s Abutton has
been released.
Incorrectly con-
nected outlets
that could cause
personal injury
are indicated by
a warning triangle
and audible sig-
nal.
The transmitter
cannot determine
whether the outlet
into which it has
been inserted is
earthed or une-
arthed. However, a
warning triangle is
always presented
if an earth connec-
tion is missing. If
the outlet is unearthed, this warning
has no signicance. Readings can
be taken, but RCD testing cannot be
performed.
The outlet’s conguration is only dis-
played on the receiver display while
the Abutton on the transmitter is
pressed in and held for 5 seconds
afterwards.
L
VS3 can display how an outlet is connected
quickly and easily. Both earthed and un-
earthed outlets can be checked.
1. Start the transmitter and receiver by
pressing the Abutton on the relevant
unit.
2. Check that the sym-
bol is shown on
the receiver’s display
and that the symbol
shows at least one bar, preferably
several.
The symbol must also be displayed.
If the symbol is not displayed press the C
button repeatedly until is displayed.
3. Insert the transmit-
ter in the outlet to be
checked.
The display on the
receiver shows a sym-
bolic image of the outlet
and also information
about the voltage and
frequency there.
Note! The trans-
mitter must have
a voltage on either
of its two connec-
tion pins to enable
display of ”U” and
”f”. If the fuse is
blown, the MCB
is switched off or
there is any other
reason for the
absence of voltage to one of the
pins, there will be no voltage and
frequency information displayed

Outlet conguration
Important information
Certain faults cannot be identied
Under certain circumstances a number of
faulty outlets can be indicated in a way which
is not correct.
When neutral is missing
When neutral is not connected
(but ground is connected) the
non-connected probe can be in-
dicated as voltage conducting.
When neutral and ground
are missing
When neither neutral nor
ground are connected all probes
can be indicated as voltage con-
ducting. e voltage is indicated
as zero volts because the reference
to ground is missing.
VS3 cannot measure the voltage if
only the live conductor is connected
and neither the neutral nor the earth
are connected. There may be danger-
ous voltage in the outlet without it
being indicated.
If the transmitter’s probes are volt-
age free (including the earth probe)
the transmitter switches off when the
Abutton is pressed. The transmitter
must be unpowered to be switched
off.
The display shifts automatically to
the Outlet menu when the A-button
is pressed on the transmitter. (if the
transmitter is in a powered outlet)

Why check phase connections?
In the event of uneven load a unit may need
to be checked to determine what loads are
on which phase.
Connect the transmitter to a wall outlet and
measure the main fuse that is overloaded.
Note the phase position. Then measure the
outlets and installations where large current
consumption can occur. Note the phase
position of these. Decide if any outlet or ma-
chine can be reconnected to obtain a more
even load.
Note that the transmitter must remain in the
same outlet, or in another outlet within the
same phase, for the phase indication to be
accurate. It is the phase that acts as refer-
ence phase.
What does the display show?
In “phase connection” mode, VS3 shows a
bar. It shows the strength of the signal recei-
ved relative to the entire sensitivity range of
the instrument. In “AUTO” mode, the scale
changes automatically from 0-25%, via 0-
50%, to 0-100%. It is possible to lock the
scale for each range.
Beside the bar is a range marker. Phase
connection is shown within this range. It is
also necessary for the transmitter to be swit-
ched on, connected to the mains and within
radio range.
Phase connections
Carry out the following
1. Start the transmitter and receiver by
pressing the Abutton on the relevant
unit.
2. Check that the symbol
is shown on the
receiver’s display and
that the symbol
shows at least one bar, preferably sev-
eral.
The symbol must also be displayed.
If the symbol is not displayed press the
Cbutton one or more times until is
displayed.
3. Connect the transmitter in the powered
outlet to be checked.
The eld strength bar
normally employs auto-
matic range selection.
The text AUTO is dis-
played below the bar.
Pressing the Abutton
repeatedly switches the
sensitivity between
(AUTO) → (0-25) →
(0-50) → (0-100).
If the transmitter
is not in an outlet
which is supplied
with voltage it can-
not give a phase
reference. This is
shown by crossed
out arrows on the
receiver display.

4. Move the top end of the receiver over the
fuses or wall outlets to be checked, or
hold it to the connection cables for those
consumers that are to be checked.
at the cable or contact that
the receiver tip measures belongs
to the same phase as the outlet
that the transmitter is connected
to is displayed here.
In this case the measurement
point belongs to the subsequent
phase, referred to the phase at
the outlet where the transmitter
is connected.
In this case the measurement
point belongs to the previous
phase, referred to the phase at
the outlet where the transmitter
is connected.
Measurements cannot be taken
