6.2. Testing Power Cable with Multimeter
A digital multimeter (DMM) is a test tool that is used to measure two or more electrical
values and is a standard diagnostic tool for technicians in the electrical industry.
Improper use of the DMM probe may damage the cable pins causing an intermittent
connection. Be sure the probe only contacts with the outside edge of the female
contact. If the probe is inserted into the contact, it may distort the pin and ruin the
connection.
