HOUSEHOLD POWER CABLES AND PHASE
Electricity is generally supplied using single-phase and
three-phase systems.
UK: Most homes in the UK use single-phase supplies.
In single-phase supplies, the current flows to and from
your household appliances using a neutral and live
wire. The neutral wire has a voltage close to zero while
the live wire carries a voltage from 120 to 240 volts.
The difference between these two wires makes the
current flow through your appliances.
Europe: Most homes in Europe use three-phase
supplies.In three-phase supplies, current flows to and
from a device through a group of three wires, each one
carrying a fluctuating phase. The three wires, therefore,
each need an individual current sensor which can be
purchased separately.
GETTING STARTED
LOCATE LIVE OUTGOING SUPPLY CABLE
The sensor clamp should be fitted over the insulated
live wire. It is recommended that you fit it over the
(outgoing) wire which comes out of the electricity meter
located in the meter box.
5
EN
This product uses Type C current sensor, do not
apply around or remove from HAZARDOUS LIVE
conductors.
Under no circumstances should any force or undue
pressure be applied to any wiring or connections.
WARNING Care must be taken at all times to avoid
touching or coming into contact with any un-insulated
wires or contacts.
If any difficulty with installation is experienced at all, the
advice of a licensed electrician should be sought.
OUTGOING
SUPPLY
SENSOR SET UP
WARNING It is recommended for current sensor
clamp(s) to be installed by a licensed electrician.
Switch off power from the mains before attaching and
detaching sensor(s).
1. Using thumb and finger, press inwards on plastic
tabs located on either side of the sensor clamp to
release top part.
2. Lift the top of the sensor away.
2
1
3. Place the main household active or live wire
(outgoing) into the electrical wire hole.
NOTE Do not pull or bend the wires. Ease the wire into
position so you can close the sensor clamp securely
around the wire.
4. Replace the top of the sensor clamp and push
down to secure.
5. Plug the sensor transmitter cable into any of the
cable sockets.

NOTE For three-phase system, attach a sensor
clamp to each live wire.
• When attaching the sensor clamp, ensure each
sensor clamp is attached to a different wire
otherwise an incorrect reading may result.
• Then plug all sensor clamp cables into the remote
transmitter. Up to three sensor clamps can be
plugged into the remote transmitter.
WARNING
• The signal wiring (approx. 1 volt, 1 milliamp) on
the sensor clamp is double insulated, suitable for
installation in domestic power supply meter box.
When passing through an enclosure opening, the
wiring should be protected from sharp edges by
fixed bushes.
• Do not use the unit if it is damaged or its safety is
impaired.
TRANSMITTER SET UP
1. Slide open the battery compartment cover.
2. Insert the batteries, matching the polarities (+ / -).
3. Press RESET after each battery change.
4. Press and hold CHECK until LED light flashes.
5. Close the battery door.
6. Mount the transmitter onto an affixed screw.
NOTE Install battery in the transmitter before the main
unit.
For best results:
• Place the sensor within 30 m (100 ft) of the main
unit.
• Place the sensor out of direct sunlight and
moisture.
• Position the sensor so that it faces the main (indoor)
unit, minimizing obstructions such as doors, walls
and furniture.

EN
TIP The transmission range may vary depending on
many factors. You may need to experiment with various
locations to get the best results.
MAIN UNIT SET UP
1. Slide open the battery compartment cover.
2. Insert the batteries, matching the polarities (+ / -).
3. Press RESET after each battery change.
4. Close the battery door.
SENSOR DATA TRANSMISSION
If main unit does not display data or after each
transmitter battery change:
1. Press and hold CHECK (located in the transmitter)
until LED light flashes. Transmitter will check for
and transmit data to the main unit every 2 seconds
for 30 seconds.
2. Press and hold UP on the main unit to search for
signal from transmitter.
UNDERSTANDING ELECTRICITY
Voltage
(volts)
Electrical potential. Fixed at 220V-
250V or 120V depending on region.
X
Current
(amps)
Amount of electricity flowing through,
e.g., a wire. (The sensor measures this
to determine watt)
=
Power
(watts)
Amount of energy being transferred.
(KW = 1000W). This type of data is
displayed on the top line of Energy
mode.
KWh is a measure of consumption. Kilowatt hour
represents the use of 1000W of electricity for 1 whole
hour, which is equivalent to ten x 100W light bulbs
operating at the same time for 1 hour.
Once cost rate of electricity has been inputted, the
monitor can arrive at an estimated cost.
NOTE This product is for educational purposes only.
Its aim is to aid understanding of the cost of operating
electrical appliances in the home. It does not replace
your accurate electricity revenue meter.

EN
DISPLAY MODES
There are 2 display modes to choose from:
COST
UP / DOWN
Real time cost
of electricity
per hour
Accumulated
cost since last
reset
ENERGY Real time
power (KW)
Accumulated
energy (KWh)
consumed
since last reset
COST RATE
To determine the approximate cost of electricity
consumption, input the cost per KWh.
To set cost rate:
1. Press and hold SET.
2. Press UP / DOWN to change values of the setting.
3. Press SET to confirm and move to the next digit.
NOTE Each utility company sets a different tariff for
electricity consumption. This rate can usually be found
on the electricity bill.
TIP Certain utility companies use a tiered cost of
electricity, whereby the rate increases after consumption
exceeds a specified amount. It is recommended that
an average value is entered as the cost rate.
I.e., Total usage is 1000KWh (500 + 500) which can
be separated as:
500 KWh at 15p = £75
500 KWh at 10p = £50
Then, £125 / 1000KWh = 12.5p
Similarly, some utility companies use different tariffs for
usage at different times of the day. It is recommended
that an average value is entered as the cost rate.
I.e., Total usage is 3000KWh (1000KWh for day rate +
2000 for night rate) which can be separated as:
1000 KWh at 15p = £150
2000 KWh at 5p = £100
Then, £250 / 3000 KWh = 8.3p
POWER SAVE
By decreasing the frequency data is received from
every 6 seconds to every 60 seconds, battery life is
extended.
To activate power save function:
• Press and hold DOWN.
PWR SAVE indicates power save function is activated.

EN
CLEAR RECORDS
NOTE When total cost reaches 999.99 or total
energy reaches 999.99KWh, digits will flash to indicate
maximum has been reached and the need to clear
records.
To clear records of TOTAL data (Cost / Energy):
• Press and hold UP and DOWN simultaneously.
RESET
Press RESET to return to the default settings.
