HOW THE OWL MICRO WORKS

Overview

This measurement category II product uses current transformer sensing technology to detect and monitor a tiny magnetic ﬁeld around your
household electricity power cable. It measures the current (Amps) being used and, by reference to the system voltage, calculates the amount of
power being used and the cost. It then transmits this information from the Transmitter wirelessly to the Display on a radio frequency of 433MHz,
from up to 30 metres (100 feet) away (unbroken transmission).

NOTE

The intention of this

product is primarily as an educational device to aid understanding of the cost of operating electrical

appliances in the home. Hence, there is no intention for the

Micro Wireless Electricity Monitor to replace your accurate electricity revenue

meter.

Household Power Cables And Phase

Most UK household electricity supplies use single-phase, but some use three phase. In single-phase supplies, the current ﬂows to and from
your household appliances using a neutral and power line. The neutral line has a voltage close to zero while the power line carries a ﬂuctuating
voltage or phase. The difference between these two lines makes the current ﬂow through your appliances.
In three phase supplies, current ﬂows to and from a device through a group of three lines - each one carrying a ﬂuctuating voltage or phase. For

3 phase supplies our

Wireless Electricity Monitor is required with a sensor connected to each of the three phase lines.

Accuracy

The

Micro Wireless Electricity Monitor has a ﬁxed voltage - 230V and used with the monitoring of current by the sensor clip enables a

calculation of KWH. Generally the device is accurate within 10%. The

Micro Wireless Electricity Monitor is not designed to replace homes

electricity meter - they are aimed to provide a very visual and accessible way for users to see the impact of different devices and usage patterns
around the home. This we hope will assist in educating users to adopt more beneﬁcial consumption habits, reduce their costs and reduce their
carbon emissions.

HINTS, TIPS & TROUBLESHOOTING

Cost of Electricity

:- Price per kWh of electricity as shown on your electricity bill.

Tiered Cost of Electricity

:- Where the ﬁrst number of kWh are at one value and everything else used is another. We recommend that you

enter an average value, calculated from your billed kWh usage (monthly/quarterly) and assuming that quarterly usage is 900kWh then Total
cost of kWh would be 210kWh @ 20.90p & 690kWh at 10.00p equalling £112-89. The average value would be £112-89 divided by 900kWh
giving 12.54p.

Multiple Timed Tariffs (ie Economy 7)

:- are not supported with OWL Micro. We recommend that you enter an average value, calculated from

your billed kWh usage (monthly/quarterly) and assuming that quarterly usage is 900kWh for day rate and 1500kWh for night rate, then Total
cost of kWh would be 900kWh @ 10.90p & 1500kWh at 4.70p equalling £168.60. The average value would be £168.60 divided by 2400kWh
giving 7.03p.

Cable Size-

The sensor is suitable to connect over a cable up to 10mm in diameter including the insulation. It is ok for the sensor to be loose

over the cable.

Display is blank

:- Ensure that the batteries are inserted the correct way around and that the batteries are not exhausted. If the batteries are

exhausted replace with new batteries. If the display does not return then contact customer.services@theowl.com.

Four dashes (----) ﬂashing on the upper part of the Display

:- The Display is in a search mode looking for a Transmitter to synchronise with.

Four dashes (----) ﬁxed on the upper part of the Display

:- The Display and Transmitter have not synchronised. Repeat the “Synchronising

the Display and Transmitter” process in the manual.

0.00 Reading on the Display

:- The sensor is not able to measure the electricity ﬂow through the Twin/Three Core cables so will return a reading

of 0.00 if the sensor is connected over the cable of an appliance.

0.00 Reading on the Display

: Possible that the Sensor has a damaged Ferrite Core. To check to see if the sensor is damaged, you will need

to unclip the sensor from the cable and inspect the Ferrite Core (U-Shaped Black Material) in the sensor lid is still in one piece and that the
corresponding faces in the sensor body are in position. If this is damaged then contact customer.services@theowl.com.

Lower reading than expected

:- If the cable is a very tight ﬁt for the sensor then it is likely the sensor is unable to be closed properly as in the

2 halves of ferrite core within the sensor do not make a ﬂush contact then the reading will be lower than measured.

Save Money with the OWL 10-step Plan

Install OWL and reduce your electricity consumption by following our ten-step plan for saving electricity

1) Change light bulbs to energy saving versions

2) Switch off electronic goods such as TV’s, videos and games consoles at wall sockets when not in use

3) Remove all telephone chargers from mains when not in use

4) Use tumble dryers less and if possible dry using a washing line

5) Fill washing machines and dish washers to maximum for each cycle

6) Wash clothes on cooler temperatures (ie 40°C 30°C)

7) Only boil the amount of water necessary when making tea or coffee
