Measuring Voltage Drop - Step By Step
Measuring voltage drop - Step by step
The step by step method is most useful for isolating excessive drops in low voltage systems (such as computer controlled systems).
Circuits in the computer controlled system operate on very low amperage.
Computer controlled operations can be adversely affected by any variation in resistance in the system. Such resistance variation may be caused by
poor connection, improper installation, improper wire gauge or corrosion.
The step by step voltage drop test can identify a component or wire with too much resistance.
CONTROL UNIT CIRCUIT TEST
Control Unit Circuit Test Case 1
System Description: When the switch is ON, the control unit lights up the lamp.
*:If high resistance exists in the switch side circuit caused by a single stand), terminal 2 does not detect approx. 0 V. Control unit does not detect
the switch is ON. Therefore, the control unit does not control ground to light up the lamp.
