quick manual - installation
The Wattcher shows your home´s total energy consumption in a beautiful way.
Together with Wattcher Online it gives insight in your daily activities and helps
you to save energy. Your Wattcher comes with the following components:
velcro tape
Sensor
Measures your electricity
use at the meter

Step 1: Determine your type of electricity meter

Electricity meters come in two types:
A electromechanical meter has a rotating metal disk.
A digital pulse meter has a blinking LED, or pulse light.
There are also LEDs with an infrared light, invisible to the human eye but visible to
the Wattcher's sensor.

Step 2: Read your C-Value

The C-value is a number on your meter. On an electromechanical meter, it states the
wheel's turning speed. On a pulse meter, it is the blink frequency. Please follow the
instructions below to read your meter's C-value. You will need this in step 5.
For Electromechanical meters:
The C-value should be written on your meter as C = ...... , a = ........ or as ...... r/kWh,
....... tr/kWh or ........ U/kWh. Write down the C-value (for example 600).
Note: if you see a = ........ on your meter, multiply that number by 60 to obtain the
correct C-value (e.g. a = 10 -> C-value = 10 x 60 = 600)
For Pulse meters:
The C-value should be written on your meter as ....... imp/kWh, ....... pulses/kWh,
........ p/kWh or ........ Wh/imp. Write down the C-value (for example 1000).
Note: if your see ..... Wh/imp, then divide 1000 by that number to get the correct
C-value (e.g. 0,5 Wh/imp -> C- value = 1000 / 0,5 = 2000). If your meter denotes
imp/kVarh or has the addition R53 or SO, that value should not be used (it indicates
the variance in usage).
Pay attention
If you have any doubts or if more than one number is written on your meter, please
check page 6 and 7 of the comprehensive manual to determine the correct C-value.
