Electrical circuit diagnostic tool

A method for running a test sequence to determine whether an electrical circuit is capable of maintaining a minimum pre-determined voltage under load, the method comprising the steps of:

• measuring a voltage value present at a point contact and displaying said measured voltage on a display;
• determining whether a button has been pressed to initiate a test sequence;
• re-measuring the voltage value present at a point contact and comparing said re-measured value to said pre-determined minimum voltage, and displaying said re-measured voltage on a display;
• if said re-measured voltage exceeds said pre-determined minimum voltage, increasing a current load on said electrical circuit in a stepwise manner and re-measuring the voltage present at said point contact with each stepwise increase in current load, and displaying said re-measured voltage on a display;
• continuing to increase a current load on said electrical circuit in a stepwise manner until such time as the re-measured voltage drops to the value of said pre-determined voltage;
• and
• measuring the current load at the time that the re-measured voltage drops to the value of said pre-determined voltage and displaying said measured current on a display.

A method for running a test sequence to determine whether an electrical circuit is capable of supplying a pre-determined minimum current while maintaining a pre-determined minimum voltage, the method comprising the steps of:

• measuring a voltage value present at a point contact and displaying said measured voltage on a display;
• determining whether a button has been pressed to initiate a test sequence and thereby ramping a current load on said electrical circuit in a stepwise manner;
• re-measuring the voltage value present at a point contact and comparing said re-measured value to said pre-determined minimum voltage;
• and
• determining whether said re-measured voltage exceeds said predetermined minimum voltage, and if so, continuing the test sequence by increasing the current load on said electrical circuit in a stepwise manner;
• and
• continuing to ramp said current load while re-measuring the voltage present at said point contact until such time as (i) either the current load exceeds said pre-determined minimum current or (ii) the voltage present at said point contact drops below said pre-determined minimum voltage;
• and
• displaying an indication that either (i) the electrical circuit is capable of supplying said pre-determined minimum current while maintaining a pre-determined minimum voltage, or (ii) the electrical circuit is not capable of supplying said pre-determined minimum current while maintaining a pre-determined minimum voltage.
