With a current sensor you can easily, quickly and reliably diagnose almost any electronic device.

1. Diagnoses Electric and Electrical
Devices

2. I-Scan uses the electrical current
consumption of an electric device to
diagnoses several different type of
failures on both Electronic and
Electrical Boards (EB) .

3. I-Scan makes the process of repairing
much more feasible and efficient with
a small adaptation of a general profile
the user is able to implement it to any
EB.

4. I-Scan also requires an interface
which couples the given EB to be
diagnoses. The needed information is
then acquired using an acquisition
card and processed by an external
PC. A user interface allows the user to
see the failure(s) on the EB being
tested.

8. In terms of electrical energy consumption there are three type of devices on a
Given Electrical Board (EB)
High Consumption Devices (HCD)
HCD>15% of the total EB’s Energy
Consumption
Medium Consumption Devices (MCD)
5%<MCD<15% of the total EB’s Energy
Consumption
Low Consumption Devices
(LCD)
LCD<5% of the total EB’s
Energy
Consumption
- A HCD, MCD, or LCD will be diagnosed as a Defective Device if its Energy consumption is 5% of its EEP
- A HCD, MCD, or LCD will be diagnosed as a Good Device if its Energy consumption is 1% of its EEP
- A given Device’s Electrical Energy Pattern (EEP) will be the range of consumption levels that
the device will have to fall into; in order to be in a good working condition.
