The Toaster Test is a simple and effective test to see if the transmitter / CT clamp is working correctly.
Since a toaster is a simple device (basically a rated heating element) we know exactly what that should read on the energy monitor display.
1. Ensure your home is in a 'steady' usage state. Often a good time is either at night, or in the morning when there is little activity in your home.
2. Record the energy monitor reading
3. Switch on the toaster
4. Re-record the energy monitor reading
On the underside of the toaster will be the power rating, and this should be the increase you see on your energy monitor display.
We recommend repeating the exercise a couple of times just incase there are fluctuations in the homes energy usage such as a fridge or aircon kicking in.
